Context: The Browns were making their first trip to San Diego since 2006. The game was back and forth, with neither team leading by more than one possession. The Chargers led 7-3 after the 1st quarter. On the Browns' first drive of the second quarter, QB Josh McCown threw a 34-yard touchdown pass to RB Duke Johnson to put the Browns up 10-7. The teams traded field goals, making it a 13-13 game at halftime. The Browns scored a field goal at the start of the 3rd quarter to go up 16-13. On the Chargers' next drive, QB Philip Rivers led the Chargers to a touchdown, going up 20-16 heading into the 4th quarter. After K Travis Coons kicked a field goal to cut the deficit to 20-19, Rivers led another touchdown drive to put the Chargers up 27-19. On the Browns' next drive, they reached the end zone, assisted by an incredible catch by TE Gary Barnidge on the Chargers' 1 yard line. They converted on the two point conversion to tie the game at 27-27 with just over 2 minutes remaining. The Chargers reached the Browns' 24 yard line with under 50 seconds to play. The Browns began to use timeouts until the Chargers faced 4th down with 2 seconds to play. After the Chargers called timeout, their kicker had an opportunity to win the game with a 39-yard field goal. The 39 yard game winning attempt was off to the right, and the game appeared to be on its way to overtime.. However, CB Tramon Williams was flagged for being offside during the play, giving the Chargers another attempt, this time from 34 yards. The field goal was converted, and the Chargers won 30-27. The Browns committed 12 penalties in the game, including this critical offside penalty.
Question: Which penalty led to the Chargers second FG attempt? | [
"offside"

Context: When you think of life in the ocean, do you think of fish? Actually, fish are not the most common life forms in the ocean. Plankton are the most common. Plankton make up one of three major groups of marine life. The other two groups are nekton and benthos. Figure 14.24 shows the three groups. Plankton are living things that float in the water. Most plankton are too small to see with the unaided eye. Some examples are shown in Figure 14.25. Plankton are unable to move on their own. Ocean motions carry them along. There are two main types of plankton: 1. Phytoplankton are plant-like plankton. They make food by photosynthesis. They live in the photic zone. Most are algae. 2. Zooplankton are animal-like plankton. They feed on phytoplankton. They include tiny animals and fish larvae. Nekton are living things that swim through the water. They may live at any depth, in the photic or aphotic zone. Most nekton are fish, although some are mammals. Fish have fins and streamlined bodies to help them swim. Fish also have gills to take oxygen from the water. Figure 14.26 shows examples of nekton. Benthos are living things on the ocean floor. Many benthic organisms attach themselves to rocks and stay in one place. This protects them from crashing waves and other water movements. Some benthic organisms burrow into sediments for food or protection. Benthic animals may crawl over the ocean floor. Examples of benthos include clams and worms. Figure 14.27 shows two other examples. Some benthos live near vents on the deep ocean floor. Tubeworms are an example (see Figure 14.28). Scalding hot water pours out of the vents. The hot water contains chemicals that some specialized bacteria can use to make food. Tubeworms let the bacteria live inside them. The bacteria get protection and the tubeworms get some of the food. Figure 14.29 shows a marine food chain. Phytoplankton form the base of the food chain. Phytoplankton are the most important primary producers in the ocean. They use sunlight and nutrients to make food by photosynthesis. Small zooplankton consume phytoplankton. Larger organisms eat the small zooplankton. Larger predators eat these consumers. In an unusual relationship, some enormous whales depend on plankton for their food. They filter tremendous amounts of these tiny creatures out of the water. The bacteria that make food from chemicals are also primary producers. These organisms do not do photosynthesis since there is no light at the vents. They do something called chemosynthesis. They break down chemicals to make food. When marine organisms die, decomposers break them down. This returns their nutrients to the water. The nutrients can be used again to make food. Decomposers in the oceans include bacteria and worms. Many live on the ocean floor. Do you know why?

"phytoplankton."

Context: To evaluate the results of facial nerve (FN) grafting using great auricular cable graft and fibrin glue without suturing to palliate FN disruption after removal of large cerebellopontine angle (CPA) vestibular schwannoma (VS) or facial nerve schwannoma (FNS). To assess whether tumor size and origin influenced the results. Retrospective review of all patients having undergone removal of FNS/VS and needing intraoperative FN repair between 2001 and 2011. FN was rehabilitated using great auricular nerve cable graft and fibrin glue (Tisseal) without stitching suture. All data recorded were reviewed to access age, sex, tumor type, and tumor size according to the Koos classification and presenting symptoms. FN function was evaluated preoperatively and at 18 months using the House-Brackmann (HB) grading system. Among the 595 patients operated for CPA schwannomas in this period, 15 patients (2.5%) underwent FN repair, including 7 cases of FNS and 8 cases of VS. Tumor removal was total in all cases. FN recovery was HB3 in 13 cases (86.7%) and HB4 in 2. The mean time to the first clinical signs of facial reinnervation was 10 months (6-12 mo). No significant relation was found between postoperative facial function and tumor size or type, even if all cases of preoperative FP were noted in FNS. Immediate FN reconstruction with fibrin glue-aided greater auricular nerve graft can effectively restore FN function with excellent outcomes. The results seem better than those observed by other authors using sutured grafts or delayed hypoglossal-facial nerve anastomosis.
Question: Which disease can be categorized using the Koos grading system? | [
"vestibular schwannoma"

Context: Humans did not reach space until the second half of the 20th century. They needed somehow to break past Earths gravity. A rocket moves rapidly in one direction. The device is propelled by particles flying out of it at high speed in the other direction. There are records of the Chinese using rockets in war against the Mongols as early as the 13th century. The Mongols then used rockets to attack Eastern Europe. Early rockets were also used to launch fireworks. Rockets were used for centuries before anyone could explain how they worked. The theory came about in 1687. Isaac Newton (16431727) described three basic laws of motion, now referred to as Newtons Laws of Motion: 1. An object in motion will remain in motion unless acted upon by a force. 2. Force equals mass multiplied by acceleration. 3. To every action, there is an equal and opposite reaction. Which of these three best explains how a rocket works? Newtons third law of motion. When a rockets propulsion pushes in one direction, the rocket moves in the opposite direction, as seen in the Figure 23.12. For a long time, many people believed that a rocket wouldnt work in space. There would be nothing for the rocket to push against. But they do work! Fuel is ignited in a chamber. The gases in the chamber explode. The explosion creates pressure that forces the gases out of one side of the rocket. The rocket moves in the opposite direction, as shown in Figure 23.13. The force pushing the rocket is called thrust. For centuries, rockets were powered by gunpowder or other solid fuels. These rockets could travel only short distances. Around the turn of the 20th century, several breakthroughs took place. These breakthroughs led to rockets that could travel beyond Earth. Liquid fuel gave rockets enough power to escape Earths gravity (Figure 23.14). By using multiple stages, empty fuel containers could drop away. This reduced the mass of the rocket so that it could fly higher. Rockets were used during World War II. The V2 was the first human-made object to travel high enough to be considered in space (Figure 23.15). Its altitude was 176 km (109 miles) above Earths surface. Wernher von Braun was a German rocket scientist. After he fled Germany in WWII, he helped the United States develop missile weapons. After the war, von Braun worked for NASA. He designed the Saturn V rocket (Figure One of the first uses of rockets in space was to launch satellites. A satellite is an object that orbits a larger object. An orbit is a circular or elliptical path around an object. Natural objects in orbit are called natural satellites. The Moon is a natural satellite. Human-made objects in orbit are called artificial satellites. There are more and more artificial satellites orbiting Earth all the time. They all get into space using some sort of rocket. Why do satellites stay in orbit? Why dont they crash into Earth due to the planets gravity? Newtons law of universal gravitation describes what happens. Every object in the universe is attracted to every other object. Gravity makes an apple fall to the ground. Gravity also keeps you from floating away into the sky. Gravity holds the Moon in orbit around Earth. It keeps Earth in orbit around the Sun. Newton used an example to explain how gravity makes orbiting possible. Imagine a cannonball launched from a high mountain, as shown in Figure 23.17. If the cannonball is launched at a slow speed, it will fall back to Earth. This is shown as paths (A) and (B). Something different happens if the cannonball is launched at a fast speed. The Earth below curves away at the same rate that the cannonball falls. The cannonball then goes into a circular orbit, as in path (C). If the cannonball is launched even faster, it could go into an elliptical orbit (D). It might even leave Earths gravity and go into space (E). Unfortunately, Newtons idea would not work in real life. A cannonball launched at a fast speed from Mt. Everest would not go into orbit.

Context: Rapid laboratory methods provide optimal support for active surveillance efforts to screen for methicillin-resistant Staphylococcus aureus (MRSA). Most laboratories struggle to determine the optimal use of resources, considering options to balance cost, speed, and diagnostic accuracy. To assess the performance of common methods, the first comparison of MRSASelect agar (MS) and CHROMagar MRSA (CA), with and without broth enrichment followed by a 24-h subculture to MS, was performed. Results were compared to those of the Xpert MRSA assay. For direct culture methods, the agreement between MS and CA was 98.8%. At 18 h, direct MS identified 93% of all positive samples from direct culture and 84% of those identified by the Xpert MRSA. For Trypticase soy broth-enriched MS culture, incubated overnight and then subcultured for an additional 24 h, the agreement with Xpert MRSA was 96%. The agreement between direct MS and Xpert MRSA was 100% when semiquantitative culture revealed a bacterial density of 2+ or greater; however, discrepancies between culture and Xpert MRSA arose for MRSA bacterial densities of 1+ or less, indicating low density as a common cause of false-negative culture results. Since 1+ or less was established as the most common MRSA carrier state, broth enrichment or PCR may be critical for the identification of all MRSA carriers who may be reservoirs for transmission. In this active-surveillance convenience sample, the use of broth enrichment followed by subculture to MS offered a low-cost but sensitive method for MRSA screening, with performance similar to that of Xpert MRSA PCR.

Context: Bob and Doug McKenzie (Rick Moranis and Dave Thomas) are two dim-witted and unemployed "hosers" living in Toronto, Ontario who find themselves in a bind when they squander their father's beer money and then run out of beer. The brothers place a live mouse in a beer bottle in an attempt to blackmail the local beer store into giving them free Elsinore beer, but are told to take up the matter at the Elsinore brewery instead. After presenting the mouse to management at the brewery, the brothers are given jobs on the bottling line inspecting the bottles for mice. They take this opportunity to drink lots of free beer off the line; later, they present their parents with a van full of free Elsinore beer products as part of their payment with their new jobs.Meanwhile, the evil owner of the brewery, Brewmeister "B.M." Smith (Max von Sydow), is perfecting a secret plan to take over the world by placing a mind-control drug in Elsinore beer which, while rendering the consumer docile, also makes him or her attack others when stimulated by certain musical tones. Smith tests this adulterated beer on patients of the conveniently located Royal Canadian Institute for the Mentally Insane, which is connected by underground tunnels to the brewery. The effects of the tainted beer are demonstrated in an extended sequence during which the mental patients don armored Star Wars-style hockey garb and, after consuming the beer, respond to synthesizer music by variously playing hockey, skating together in sync, and brawling on the ice.It seems the former brewery owner John Elsinore has recently died under mysterious circumstances and his daughter, Pam (Lynne Griffin), having recently turned 21, has been given full control of the Elsinore brewery. Pam's incompetent uncle Claude (Paul Dooley), in the interim, had married her widowed mother and is reluctant to give up his recently-gained control of the brewery. The reason for this is further revealed to be that the bumbling Claude is collaborating with Brewmeister Smith, for whom he is a buffoonish toady, providing a cover for the Brewmeister's nefarious plans. Bob and Doug blunder into the midst of these plans when they rescue Pam from a malfunctioning security gate and both become fast friends with her.While exploring the massive brewery, Bob and Doug find a shuttered cafeteria containing an old Galactic Border Patrol video game that supernaturally reveals that Brewmeister Smith murdered John Elsinore and that Uncle Claude was deeply involved. Additionally, while poking around the brewery, Bob and Doug meet a one time hockey great, Jean "Rosie" LeRose (Angus MacInnes), whom Bob recognizes from the hockey card he has back home at his parents' house. Having suffered a career-ending nervous breakdown and fallen under Smith's control, Rosie gets locked up at the insane asylum but is determined to fight against the Brewmeister's plot for world domination.Eventually, Bob and Doug wander into Brewmeister's operations room while he is away, and Doug takes a record disk of John Elsinore's murder, believing that it is a New Wave bootleg record. Immediately afterward, Brewmeister and Claude shoot the brothers with tranquilizers. They then dress up in the brothers clothes where they are shown on security camera shooting tranquilizer darts at Pam and a friendly associate, named Henry Green, and put their unconcious bodies in kegs.When Bob and Doug wake up, they are back in their van, convinced that their suspicious discoveries were all just dreams, and they are instructed by Claude to deliver two kegs of beer (actually containing an unconscious Pam and her father's friend, Henry Green) to a party at the bottom of a big hill. However, the brakes have been modified to only allow two stops before giving out altogether.Nevertheless, as Bob and Doug drive, they soon get distracted and decide to stop off at their house to feed their dog. They also leave behind the incriminating record disk of Brewmeister and Claude's actions at their house. Having wasted one stop prior, they find themselves unable to stop the now-speeding vehicle and eventually wind up jumping off of the Toronto pier into Lake Ontario. Rosie arrives and tries to rescue Pam who

Context: The endocrine system is a system of glands that release chemical messenger molecules into the blood stream. The messenger molecules are called hormones. Hormones act slowly compared with the rapid transmission of electrical impulses of the nervous system. Endocrine hormones must travel through the bloodstream to the cells they control, and this takes time. On the other hand, because endocrine hormones are released into the bloodstream, they travel to cells everywhere in the body. For a good visual introduction to the endocrine system, watch this short video: http MEDIA Click image to the left or use the URL below. URL: An endocrine gland is a gland that secretes hormones into the bloodstream for transport around the body (instead of secreting hormones locally, like sweat glands in the skin). Major glands of the endocrine system are shown in Figure 20.17. The glands are the same in males and females except for the ovaries and testes. The hypothalamus is actually part of the brain, but it also secretes hormones. Some of its hormones go directly to the pituitary gland in the endocrine system. These hypothalamus hormones tell the pituitary to either secrete or stop secreting its hormones. In this way, the hypothalamus provides a link between the nervous and endocrine systems. The hypothalamus also produces hormones that directly regulate body processes. For example, it produces antid- iuretic hormone. This hormone travels to the kidneys and stimulates them to conserve water by producing more concentrated urine. The pea-sized pituitary gland is just below the hypothalamus and attached directly to it. The pituitary receives hormones from the hypothalamus. It also secretes its own hormones. Most pituitary hormones control other endocrine glands. Thats why the pituitary gland is called the master gland of the endocrine system. Table Pituitary Hormone Adrenocorticotropic (ACTH) hormone Target Glands/Cells adrenal glands Thyroid-stimulating (TSH) Growth hormone (GH) hormone thyroid gland Follicle-stimulating (FSH) hormone body cells ovaries or testes Luteinizing hormone (LH) ovaries or testes Prolactin (PRL) mammary glands Effects(s) Stimulates the cortex (outer layer) of the adrenal glands to secrete their hormones Stimulates the thyroid gland to se- crete its hormones Stimulates body cells to make pro- teins and grow Stimulates the ovaries to develop mature eggs; stimulates the testes to produce sperm Stimulates the ovaries or testes to secrete sex hormones; stimulates the ovaries to release eggs Stimulates the mammary glands to produce milk There are several other endocrine glands. Find them in Figure 20.17 as you read about them below. The thyroid gland is a relatively large gland in the neck. Hormones secreted by the thyroid gland include thyroxin. Thyroxin increases the rate of metabolism in cells throughout the body. The pancreas is a large gland located near the stomach. Hormones secreted by the pancreas include insulin. Insulin helps cells absorb glucose from the blood. It also stimulates the liver to take up and store excess glucose. The two adrenal glands are glands located just above the kidneys. Each adrenal gland has an outer layer (cortex) and inner layer (medulla) that secrete different hormones. The hormone adrenaline is secreted by the inner layer. It prepares the body to respond to emergencies. For example, it increases the amount of oxygen and glucose going to the muscles. The gonads are glands that secrete sex hormones. Male gonads are called testes. They secrete the male sex hormone testosterone. The female gonads are called ovaries. They secrete the female sex hormone estrogen. Sex hormones stimulate the changes of puberty. They also control the production of sperm or eggs by the gonads. Endocrine hormones travel throughout the body in the blood. However, each endocrine hormone affects only certain cells, called target cells. A target cell is the type of cell on which a given endocrine hormone has an effect. A target cell is affected by a given hormone because it has proteins on its surface to which the hormone can bind. When the hormone binds to target cell proteins, it causes changes inside the cell. For example, binding of the hormone might cause the release of enzymes inside the cell. The enzymes then influence cell processes. Endocrine hormones control many cell activities, so they are very important for homeostasis.

Context: Metastasis is the major factor affecting patient survival in ovarian cancer. However, its molecular mechanisms remain unclear. Our study used isogenic pairs of low- and high-invasive ovarian cancer cell lines to demonstrate the downregulation of miRNA-138 in the highly invasive cells, and its functioning as an inhibitor of cell migration and invasion. An orthotopic xenograft mouse model further demonstrated that the expression of miRNA-138 inhibited ovarian cancer metastasis to other organs. Results indicated that miR-138 directly targeted SRY-related high mobility group box 4 (SOX4) and hypoxia-inducible factor-1 (HIF-1), and overexpression of SOX4 and HIF-1 effectively reversed the miR-138-mediated suppression of cell invasion. Epidermal growth factor receptor acted as the downstream molecule of SOX4 by way of direct transcriptional control, whereas Slug was the downstream molecule of HIF-1 by way of proteasome-mediated degradation. Analysis of human ovarian tumors further revealed downregulation of miR-138 and upregulation of SOX4 in late-stage tumors. Patients with miR-138(low)/SOX(high) signature are predominant in late stage and tend to have malignant phenotypes including lymph nodes metastasis, larger ascites volume and higher tumor grade. Our study demonstrates the role and clinical relevance of miR-138 in ovarian cancer cell invasion and metastasis, providing a potential therapeutic strategy for suppression of ovarian cancer metastasis by targeting SOX4 and HIF-1 pathways.

Context: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease, which causes progressive and eventually fatal loss of motor function. Here, we describe genetic and pathologic characterization of brain tissue banked from 19 ALS patients over nearly 20years at the Department of Anatomy and the Centre for Brain Research, University of Auckland, New Zealand. We screened for mutations in SOD1, TARDBP, FUS, and C9ORF72 genes and for neuropathology caused by phosphorylated TDP-43, dipeptide repeats (DPRs), and ubiquilin. We identified 2 cases with C9ORF72 repeat expansions. Both harbored phosphorylated TDP-43 and DPR inclusions. We show that DPR inclusions can incorporate or occur independently of ubiquilin. We also identified 1 case with a UBQLN2 mutation, which showed phosphorylated TDP-43 and characteristic ubiquilin protein inclusions. This is the first study of ALS genetics in New Zealand, adding New Zealand to the growing list of countries in which C9ORF72 repeat expansion and UBQLN2 mutations are detected in ALS cases.

Context: We need natural resources for just about everything we do. We need them for food and clothing, for building materials and energy. We even need them to have fun. Table 20.1 gives examples of how we use natural resources. Can you think of other ways we use natural resources? Use Vehicles Resources Rubber for tires from rubber trees Steel frames and other metal parts from minerals such as iron Example iron ore Use Electronics Resources Plastic cases from petroleum prod- ucts Glass screens from minerals such as lead Example lead ore Homes Nails from minerals such as iron Timber from trees spruce timber Jewelry Gemstones such as diamonds Minerals such as silver silver ore Food Sunlight, water, and soil Minerals such as phosphorus corn seeds in soil Clothing Wool from sheep Cotton from cotton plants cotton plants Recreation Water for boating and swimming Forests for hiking and camping pine forest Some natural resources are renewable. Others are not. It depends in part on how we use them. Renewable resources can be renewed as they are used. An example is timber, which comes from trees. New trees can be planted to replace those that are cut down. Sunlight is a renewable resource. It seems we will never run out of that! Just because a resource is renewable, it doesnt mean we should use it carelessly. If we arent careful, we can pollute resources. Then they may no longer be fit for use. Water is one example. If we pollute a water source it may not be usable for drinking, bathing or any other type of use. We can also overuse resources that should be renewable. In this case the resources may not be able to recover. For example, fish are renewable resources. Thats because they can reproduce and make more fish. But water pollution and overfishing can cause them to die out if their population becomes too low. Figure 20.1 shows another example. Some resources cant be renewed. At least, they cant be renewed fast enough to keep up with use. Fossil fuels are examples. It takes millions of years for them to form. We are using them up much more quickly. Elements that are used to produce nuclear power are other examples. They include uranium. This element is already rare. Sooner or later, it will run out. Supplies of non-renewable resources are shrinking. This makes them harder to get. Oil is a good example. Oil reserves beneath land are running out. So oil companies have started to drill for oil far out in the ocean. This costs more money. Its also more dangerous. Figure 20.2 shows an oil rig that exploded in 2010. The explosion killed 11 people. Millions of barrels of oil spilled into the water. It took months to plug the leak. Rich nations use more natural resources than poor nations. In fact, the richest 20 percent of people use 85 percent of the worlds resources. What about the poorest 20 percent of people? They use only 1 percent of the worlds resources. You can see this unequal distribution of oil resources in Figure 20.3. Imagine a world in which everybody had equal access to resources. Some people would have fewer resources than they do now. But many people would have more. In the real world, the difference between rich and poor just keeps growing. Every 20 minutes, the human population adds 3,500 more people. More people need more resources. For example, we now use five times more fossil fuels than we did in 1970. The human population is expected to increase for at least 40 years. What will happen to resource use? How can we protect Earths natural resources? One answer is conservation. This means saving resources. We need to save resources so some will be left for the future. We also need to protect resources from pollution and overuse. When we conserve resources, we also cut down on the trash we produce. Americans throw out 340 million tons of trash each year. We throw out 2.5 million plastic bottles alone every hour! Most of what we throw out ends up in landfills. You can see a landfill in Figure 20.4. In a landfill, all those plastic bottles take hundreds of

Context: In 1851, a French scientist named Lon Foucault took an iron sphere and hung it from a wire. He pulled the sphere to one side and then released it, as a pendulum. Although a pendulum set in motion should not change its motion, Foucault observed that his pendulum did seem to change direction relative to the circle below. Foucault concluded that Earth was moving underneath the pendulum. People at that time already knew that Earth rotated on its axis, but Foucaults experiment was nice confirmation. Imagine a line passing through the center of Earth that goes through both the North Pole and the South Pole. This imaginary line is called an axis. Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earths rotation. An observer in space will see that Earth requires 23 hours, 59 minutes, and 4 seconds to make one complete rotation on its axis. But because Earth moves around the Sun at the same time that it is rotating, the planet must turn just a little bit more to reach the same place relative to the Sun. Hence the length of a day on Earth is actually 24 hours. At the Equator, the Earth rotates at a speed of about 1,700 km per hour, but at the poles the movement speed is nearly nothing. Earth rotates once on its axis about every 24 hours. To an observer looking down at the North Pole, the rotation appears counterclockwise. From nearly all points on Earth, the Sun appears to move across the sky from east to west each day. Of course, the Sun is not moving from east to west at all; Earth is rotating. The Moon and stars also seem to rise in the east and set in the west. Earths rotation means that there is a cycle of daylight and darkness approximately every 24 hours, the length of a day. Different places experience sunset and sunrise at different times and the amount of daylight and darkness also differs by location. Shadows are areas where an object obstructs a light source so that darkness takes on the form of the object. On Earth, a shadow can be cast by the Sun, Moon, or (rarely) Mercury or Venus.

Context: In 1982, in New Jersey, Gracie (Mary Ashleigh Green) is in a school playground where one boy is bullying another. She steps in and beats up the bully to help the victim, a boy she likes. But instead of being grateful, he feels humiliated at being rescued "by a girl," and gets angry at her. She promptly punches him in the nose and then sulks alone in the playground. Fast-forward to the present day, and Gracie Hart (Sandra Bullock) is an FBI Special Agent. In the middle of an operation against Russian mobsters, the target starts to choke on some food, and Gracie disobeys her superior's command in order to prevent the target from choking. As a result, a member of her squad gets shot, and she is reprimanded by being reassigned to a desk job. Soon afterwards, the bureau learns that there has been a bomb threat against the 75th annual Miss United States beauty pageant in San Antonio, Texas, which the bureau determines came from the notorious domestic terrorist known as "The Citizen". Gracie's partner, Special Agent Eric Matthews (Benjamin Bratt), is chosen to lead the mission to prevent the attack. Despite Eric's position as a lead agent in charge, it is apparent that Gracie is the more capable agent, as Eric is unsure of how to proceed and takes credit for Gracie's suggestions. One of Gracie's suggestions is to put an agent undercover at the pageant. Gracie's male colleagues then proceed to have a bit of fun running the digital images of female and male agents through a website meant for children to play dress up with their dolls. Despite the immature and chauvinistic actions of the agents, Eric recognizes that Gracie is the female FBI agent best qualified for the undercover job. Beauty pageant coach Victor Melling (Michael Caine), whose reputation was ruined after his last contestant criticized his methods, teaches the tomboyish Gracie how to dress, walk, and act like a contestant. She is not used to such behavior, however, and sees the pageant and its participants as "antifeminist ". Eventually though Victor and Gracie come to respect each other's strengths. Representing New Jersey as "Gracie Lou Freebush", Gracie impresses the audience by playing the glass harp and demonstrating self-defense techniques during the talent competition. She also unexpectedly becomes friends with the other contestants, in particular Miss Rhode Island, Cheryl Frasier (Heather Burns) Several suspects emerge, including the corrupt competition director and former pageant winner Kathy Morningside (Candice Bergen); her unpleasant assistant Frank Tobin (Steve Monroe); the veteran pageant MC Stan Fields (William Shatner) who, like Kathy, is being replaced with a younger person; and last but not least Cheryl, who appears to have a history as a radical animal rights activist. While Gracie takes Cheryl and some of the other girls out partying, in an attempt to seek out more information about Cheryl's past through "girl talk", The Citizen is arrested elsewhere on an unrelated charge. After hearing what some of the other contestants said about Kathy Morningside's past (she won the pageant only after the original winner "mysteriously" contracted food poisoning), Gracie begins to suspect her, and is worried about the safety of the girls. Her boss thinks that her suspicions are groundless and that the pageant is out of danger now that the Citizen has been arrested. He calls off the mission. Gracie opts to turn in her badge and gun and continue the investigation alone. Eric initially fails to support Gracie and is about to return to the bureau when he figures out that Gracie's suspicions must be correct, and returns to help her. In the final round of the pageant, Gracie earns 1st Runner up while Cheryl becomes Miss United States. Gracie realizes that Kathy Morningside and Frank Tobin unknown to anyone (except Victor) is Kathy's son impersonated "The Citizen" and made the threat. Because she was going to be fired after the pageant was over, Kathy and her son were planning to murder the newly crowned pageant winner on stage by putting an explosive device in her

Context: Light-harvesting pigment-protein complex of Photosystem II (LHCII) is the largest photosynthetic antenna complex of plants and the most abundant membrane protein in the biosphere. Plant fitness and productivity depend directly on a balance between excitations in the photosynthetic apparatus, generated by captured light quanta, and the rate of photochemical processes. Excess excitation energy leads to oxidative damage of the photosynthetic apparatus and entire organism and therefore the balance between the excitation density and photosynthesis requires precise and efficient regulation, operating also at the level of antenna complexes. We show that illumination of the isolated LHCII leads to isomerization of the protein-bound neoxanthin from conformation 9'-cis to 9',13- and 9',13'-dicis forms. At the same time light-driven excitation quenching is observed, manifested by a decrease in chlorophyll a fluorescence intensity and shortened fluorescence lifetimes. Both processes, the neoxanthin isomerization and the chlorophyll excitation quenching, are reversible in dim light. The results of the 77K florescence measurements of LHCII show that illumination is associated with appearance of the low-energy states, which can serve as energy traps in the pigment-protein complex subjected to excess excitation. Possible sequence of the molecular events is proposed, leading to a protective excess excitation energy quenching: neoxanthin photo-isomerizationformation of LHCII supramolecular structures which potentiate creation of energy trapsexcitation quenching.

Context: What causes clouds to form? And in general, how does matter change from one state to another? As you may have guessed, changes in energy are involved. Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matters chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. These changes are shown in Figure 4.18. Each is described in detail below. Energy is always involved in changes of state. Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings. The amount of energy in matter can be measured with a thermometer. Thats because a thermometer measures temperature, and temperature is the average kinetic energy of the particles of matter. You can learn more about energy, temperature, and changes of state at this URL: [Link] Think about how you would make ice cubes in a tray. First you would fill the tray with water from a tap. Then you would place the tray in the freezer compartment of a refrigerator. The freezer is very cold. What happens next? The warmer water in the tray loses heat to the colder air in the freezer. The water cools until its particles no longer have enough energy to slide past each other. Instead, they remain in fixed positions, locked in place by the forces of attraction between them. The liquid water has changed to solid ice. Another example of liquid water changing to solid ice is pictured in Figure 4.19. The process in which a liquid changes to a solid is called freezing. The temperature at which a liquid changes to a solid is its freezing point. The freezing point of water is 0C (32F). Other types of matter may have higher or lower freezing points. For example, the freezing point of iron is 1535C. The freezing point of oxygen is -219C. If you took ice cubes out of a freezer and left them in a warm room, the ice would absorb energy from the warmer air around it. The energy would allow the particles of frozen water to overcome some of the forces of attraction holding them together. They would be able to slip out of the fixed positions they held as ice. In this way, the solid ice would turn to liquid water. The process in which a solid changes to a liquid is called melting. The melting point is the temperature at which a solid changes to a liquid. For a given type of matter, the melting point is the same as the freezing point. What is the melting point of ice? What is the melting point of iron, pictured in Figure 4.20? If you fill a pot with cool tap water and place the pot on a hot stovetop, the water heats up. Heat energy travels from the stovetop to the pot, and the water absorbs the energy from the pot. What happens to the water next? If water gets hot enough, it starts to boil. Bubbles of water vapor form in boiling water. This happens as particles of liquid water gain enough energy to completely overcome the force of attraction between them and change to the gaseous state. The bubbles rise through the water and escape from the pot as steam. The process in which a liquid boils and changes to a gas is called vaporization. The temperature at which a liquid boils is its boiling point. The boiling point of water is 100C (212F). Other types of matter may have higher or lower boiling points. For example, the boiling point of table salt is 1413C. The boiling point of nitrogen is -196C. A liquid can also change to a gas without boiling. This process is called evaporation. It occurs when particles at the exposed surface of a liquid absorb just enough energy to pull away from the liquid and escape into the air. This happens faster at warmer temperatures. Look at the puddle in Figure 4.21.

New Orleans had three of the first four scoring plays of the game. Drew Brees hit Austin Johnson with a 14-yard TD pass, Shayne Graham made good on a 27-yard field goal, and Kenny Stills caught a 46-yard TD pass from Brees. Meanwhile, the Lions could only muster a 21-yard field goal by Matt Prater, falling behind 17-3. Detroit closed the gap to 17-10 in the third quarter after a 1-yard TD run by Joique Bell. Two more Shayne Graham field goals, however, gave the Saints a seemingly comfortable 23-10 lead with 5:24 to play in the game. With under four minutes to play, Matthew Stafford connected with Golden Tate on a 73-yard catch-and-run, making the score 23-17. On the Saints' next possession, Glover Quin picked off a third-and-ten Drew Brees pass, returning it to the New Orleans 14-yard line. At the 1:48 mark, Corey Fuller made a leaping catch of a 5-yard TD pass from Stafford for the winning touchdown in a 24-23 game.

Context: Love Canal gained worldwide attention in the late 1970s when the press started covering its story. The story is outlined below and illustrated in Figure 19.9. The Love Canal disaster actually began back in the mid 1900s. The disaster continues even today. Starting in the early 1940s, a big chemical company put thousands of barrels of chemical waste into an old canal. Over the next 10 years, the company dumped almost 22,000 tons of chemicals into the ground! In the early 1950s, the company covered over the barrels in the canal with soil. Then they sold the land to the city for just a dollar. The city needed the land in order to build an elementary school. The company warned the city that toxic waste was buried there. But they thought the waste was safe. The school and hundreds of homes were also built over the old canal. As it turned out, the cheap price was no bargain. Chemicals started leaking from the barrels. Chemicals seeped into basements. Chemicals bubbled up to the surface of the ground. In some places, plants wouldnt even grow on the soil. People noticed bad smells. Many got sick, especially the children. Residents wanted to know if the old chemicals were the cause. But they had a hard time getting officials to listen. So they demonstrated and demanded answers. Finally, the soil was tested and was found to be contaminated with harmful chemicals. For example, it contained a lot of lead and mercury. Both can cause permanent damage to the human nervous system. The school was closed. More than 200 homes were evacuated. Much of the Love Canal neighborhood was bulldozed away. The area had a massive clean-up effort. The cleanup cost millions of dollars. More than three decades later, much of Love Canal is still too contaminated to be safe for people. Love Canal opened peoples eyes to toxic waste burial. They realized there must be other Love Canals all over the country. Thousands of contaminated sites were found. The Superfund Act was passed in 1980. The law required that money be set aside for cleanup of toxic waste sites, like the Elizabeth Copper Mine in Vermont (see the far-right image in Figure 19.9). The law also required safer disposal of hazardous waste in the future. Love Canal highlighted the problem of pollution by hazardous waste. Hazardous waste is any waste that is dangerous to the health of people or the environment. It may be dangerous because it is toxic, corrosive, flammable, or explosive. Toxic waste is poisonous. Toxic waste may cause cancer or birth defects in people. It may also harm other living things. Corrosive waste is highly reactive with other substances. Corrosive waste may cause burns or destroy other materials that it touches. Flammable waste can burn easily. It may also give off harmful fumes when it burns. Explosive waste is likely to explode. The risk of explosion may be greater if the waste is mixed with other substances. Table 19.1 shows some examples of hazardous waste. Look closely. Are any of these examples lurking around your home? Example Description Cars contain toxic fluids such as brake fluid. The fluids may also be corrosive and flammable. This photo shows one way the fluids can end up in the ground. Cars use gas and oil. These materials are toxic and flammable. They pollute the land when they leak or spill. Batteries contain toxic and corrosive materials. People often toss them in the trash, but they should be disposed of properly. Electronics, such as old computers, contain toxic chem- icals. They may be sent to landfills where the toxic materials end up in the ground. Medical waste can contain many hazards: Human body fluids may cause disease; old thermometers may contain toxic mercury; and pharmaceuticals may be toxic to people and other living things. Example Description Paints can be both toxic and flammable. Paints may spill on the ground or be thrown improperly in the trash. Chemicals are applied to farm fields and lawns. They include fertilizers, herbicides, and pesticides. Many of these chemicals are toxic to people and other animals. The greatest source of hazardous waste is industry. Agriculture is another major

Context: Transcription-coupled repair (TCR) is a universal sub-pathway of the nucleotide excision repair (NER) system that is limited to the transcribed strand of active structural genes. It accomplishes the preferential elimination of transcription-blocking DNA lesions and permits rapid resumption of the vital process of transcription. A defect in TCR is responsible for the rare hereditary disorder Cockayne syndrome (CS). Recently we found that mutations in the ERCC6 repair gene, encoding a putative helicase, underly the repair defect of CS complementation group B. Here we report the cloning and characterization of the Saccharomyces cerevisiae homolog of CSB/ERCC6, which we designate RAD26. A rad26 disruption mutant appears viable and grows normally, indicating that the gene does not have an essential function. In analogy with CS, preferential repair of UV-induced cyclobutane pyrimidine dimers in the transcribed strand of the active RBP2 gene is severely impaired. Surprisingly, in contrast to the human CS mutant, yeast RAD26 disruption does not induce any UV-, cisPt- or X-ray sensitivity, explaining why it was not isolated as a mutant before. Recovery of growth after UV exposure was somewhat delayed in rad26. These findings suggest that TCR in lower eukaryotes is not very important for cell survival and that the global genome repair pathway of NER is the major determinant of cellular resistance to genotoxicity.

Context: Two functions of the female reproductive system are similar to the functions of the male reproductive system: producing gametes and secreting a major sex hormone. In the case of females, however, the gametes are eggs, and they are produced by the ovaries. The hormone is estrogen, which is the main sex hormone in females. Estrogen has two major roles: During adolescence, estrogen causes the changes of puberty. It causes the reproductive organs to mature. It also causes other female traits to develop. For example, it causes the breasts to grow and the hips to widen. During adulthood, estrogen is needed for a woman to release eggs from the ovaries. The female reproductive system has another important function, which is not found in males. It supports a baby as it develops before birth. It also gives birth to the baby at the end of pregnancy. The female reproductive organs include the ovaries, fallopian tubes, uterus, and vagina. These organs are shown in Figure 22.3, along with some other structures of the female reproductive system. Find each organ in the drawing as you read about it below. For a cartoon about the female reproductive system, watch this video: [Link] The two ovaries are small, oval organs on either side of the abdomen. Each ovary contains thousands of eggs. However, the eggs do not develop fully until a female has gone through puberty. Then, about once a month, an egg is released by one of the ovaries. The ovaries also secrete estrogen. The two fallopian tubes are thin tubes that are connected to the uterus and extend almost to the ovaries. The upper end of each fallopian tube has fingers (called fimbriae) that sweep an egg into the fallopian tube when it is released by the ovary. The egg then passes through the fallopian tube to the uterus. If an egg is fertilized, this occurs in the fallopian tube. The uterus is a hollow organ with muscular walls. The uterus is where a baby develops until birth. The walls of the uterus stretch to accommodate the growing fetus. The muscles in the walls contract to push the baby out during birth. The uterus is connected to the vagina by a small opening called the cervix. The vagina is a cylinder-shaped organ that opens to the outside of the body. The other end joins with the uterus. Sperm deposited in the vagina swim up through the cervix, into the uterus, and from there into a When a baby girl is born, her ovaries contain all of the eggs they will ever produce. But these eggs are not fully developed. They develop only after the female reaches puberty at about age 12 or 13. Then, just one egg develops each month until she reaches her 40s or early 50s. Human eggs are very large cells. In fact, they are the largest of all human cells. You can even see an egg without a microscope. Its almost as big as the period at the end of this sentence. Like a sperm cell, an egg cell is a haploid cell with half the number of chromosomes of other cells in the body. Unlike a sperm cell, the egg lacks a tail and contains a lot of cytoplasm. Egg production takes place in the ovaries. It occurs in several steps: 1. Before birth, special cells in the ovaries go through mitosis to make identical daughter cells. 2. The daughter cells then start to divide by meiosis. However, they go though only the first of the two cell divisions of meiosis at this time. They remain in that stage until the girl goes through puberty. 3. After puberty, an egg develops in an ovary about once a month. As you can see in Figure 22.4, the egg rests in a nest of cells called a follicle. The follicle and egg grow larger and go through other changes. 4. After a couple of weeks, the egg bursts out of the follicle and through the wall of the ovary. This is called ovulation. After ovulation occurs, the moving fingers of the nearby fallopian tube sweep the egg into the tube. Fertilization may occur if sperm reach the egg while it is

Context: Radioactivity is the ability of an atom to emit, or give off, charged particles and energy from the nucleus. The charged particles and energy are called by the general term radiation. Only unstable nuclei emit radiation. When they do, they gain or lose protons. Then the atoms become different elements. (Be careful not to confuse this radiation with electromagnetic radiation, which has to do with the light given off by atoms as they absorb and then emit energy.) Radioactivity was discovered in 1896 by a French physicist named Antoine Henri Becquerel. Becquerel was experimenting with uranium, which glows after being exposed to sunlight. Becquerel wanted to see if the glow was caused by rays of energy, like rays of light and X-rays. He placed a bit of uranium on a photographic plate. The plate was similar to film thats used today to take X-rays. You can see an example of an X-ray in Figure 11.1. As Becquerel predicted, the uranium left an image on the photographic plate. This meant that uranium gives off rays after being exposed to sunlight. Becquerel was a good scientist, so he wanted to repeat his experiment to confirm his results. He placed more uranium on another photographic plate. However, the day had turned cloudy, so he tucked the plate and uranium in a drawer to try again another day. He wasnt expecting the uranium to leave an image on the plate without being exposed to sunlight. To his surprise, there was an image on the plate in the drawer the next day. Becquerel had discovered that uranium gives off rays without getting energy from light. He had discovered radioactivity, for which he received a Nobel prize. To learn more about the importance of Becquerels research, go to this URL: [Link] Another scientist, who worked with Becquerel, actually came up with the term "radioactivity." The other scientist was the French chemist Marie Curie. She went on to discover the radioactive elements polonium and radium. She won two Nobel Prizes for her discoveries. You can learn more about Marie Curie at this URL: [Link] Isotopes are atoms of the same element that differ from each other because they have different numbers of neutrons. Many elements have one or more isotopes that are radioactive. Radioactive isotopes are called radioisotopes. An example of a radioisotope is carbon-14. All carbon atoms have 6 protons, and most have 6 neutrons. These carbon atoms are called carbon-12, where 12 is the mass number (6 protons + 6 neutrons). A tiny percentage of carbon atoms have 8 neutrons instead of the usual 6. These atoms are called carbon-14 (6 protons + 8 neutrons). The nuclei of carbon-14 are unstable because they have too many neutrons. To be stable, a small nucleus like carbon, with just 6 protons, must have a 1:1 ratio of protons to neutrons. In other words, it must have the same number of neutrons as protons. In a large nucleus, with many protons, the ratio must be 2:1 or even 3:1 protons to neutrons. In elements with more than 83 protons, all the isotopes are radioactive (see Figure 11.2). The force of repulsion among all those protons overcomes the strong force holding them together. This makes the nuclei unstable and radioactive. Elements with more than 92 protons have such unstable nuclei that these elements do not even exist in nature. They exist only if they are created in a lab. A low level of radiation occurs naturally in the environment. This is called background radiation. It comes from various sources. One source is rocks, which may contain small amounts of radioactive elements such as uranium. Another source is cosmic rays. These are charged particles that arrive on Earth from outer space. Background radiation is generally considered to be safe for living things. A source of radiation that may be more dangerous is radon. Radon is a radioactive gas that forms in rocks underground. It can seep into basements and get trapped inside buildings. Then it may build up and become harmful to people who breathe it. Other sources of radiation are described in the interactive animation at this URL: [Link] You may have seen a sign like

Context: The outcrop in the Figure 1.1 is at Checkerboard Mesa in Zion National Park, Utah. It has a very interesting pattern on it. As a geology student you may ask: how did this rock form? If you poke at the rock and analyze its chemistry you will see that its made of sand. In fact, the rock formation is called the Navajo sandstone. But knowing that the rock is sandstone doesnt tell you how it formed. It would be hard to design an experiment to show how this rock formed. But we can make observations now and apply them to this rock that formed long ago. James Hutton came up with this idea in the late 1700s. The present is the key to the past. He called this the principle of uniformitarianism. It is that if we can understand a geological process now and we find evidence of that same Checkerboard Mesa in Zion National Park, Utah. process in the past, then we can assume that the process operated the same way in the past. Hutton speculated that it has taken millions of years to shape the planet, and it is continuing to be changed. He said that there are slow, natural processes that changed, and continue to change, the planets landscape. For example, given enough time, a stream could erode a valley, or sediment could accumulate and form a new landform. Lets go back to that outcrop. What would cause sandstone to have layers that cross each other, a feature called cross-bedding? In the photo of the Mesquite sand dune in Death Valley National Park, California (Figure 1.2), we see that wind can cause cross-bedding in sand. Cross-bedding is due to changes in wind direction. There are also ripples caused by the wind waving over the surface of the dune. Since we can observe wind forming sand dunes with these patterns now, we have a good explanation for how the Navajo sandstone formed. The Navajo sandstone is a rock formed from ancient sand dunes in which wind direction changed from time to time. This is just one example of how geologists use observations they make today to unravel what happened in Earths past. Rocks formed from volcanoes, oceans, rivers, and many other features are deciphered by looking at the geological work those features do today. Click image to the left or use the URL below. URL:

Context: In previous concepts, you learned about B and T cells, special types of white blood cells that help your body to fight off a specific pathogen. They are necessary when the body is fighting off an infection. But what happens to them after the pathogen has been destroyed? Most B and T cells die after an infection has been brought under control. But some of them survive for many years. They may even survive for a persons lifetime. These long-lasting B and T cells are called memory cells. They allow the immune system to remember the pathogen after the infection is over. If the pathogen invades the body again, the memory cells will start dividing in order to fight the pathogen or disease. These dividing cells will quickly produce a new army of B or T cells to fight the pathogen. They will begin a faster, stronger attack than the first time the pathogen invaded the body. As a result, the immune system will be able to destroy the pathogen before it can cause an infection. Being able to attack the pathogen in this way is called immunity. Immunity can also be caused by vaccination. Vaccination is the process of exposing a person to a pathogen on purpose in order to develop immunity. In vaccination, a modified pathogen is usually injected under the skin by a shot. Only part of the pathogen is injected, or a weak or dead pathogen is used. It sounds dangerous, but the shot prepares your body for fighting the pathogen without causing the actual illness. Vaccination triggers an immune response against the injected antigen. The body prepares "memory" cells for use at a later time, in case the antigen is ever encountered again. Essentially, a vaccine imitates an infection, triggering an immune response, without making a person sick. In many countries, children receive their first vaccination at birth with the Hepatitis B shot, which protects infants from Hepatitis B, a serious liver disease. Before vaccines, many children died from diseases that vaccines now prevent, such as whooping cough, measles, and polio. Those same germs exist today, but because babies are now protected by vaccines, we do not see these diseases nearly as often. Diseases you have probably been vaccinated against include measles, mumps, and chicken pox. How does a vaccine work? See How a Vaccine Works at and The History of Vaccines at .

Context: Groups 13-16 of the periodic table (orange in the Figure 1.1) are the only groups that contain elements classified as metalloids. Unlike other groups of the periodic table, which contain elements in just one class, groups 13-16 contain elements in at least two different classes. In addition to metalloids, they also contain metals, nonmetals, or both. Groups 13-16 fall between the transition metals (in groups 3-12) and the nonmetals called halogens (in group 17). Metalloids are the smallest class of elements, containing just six members: boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). Metalloids have some properties of metals (elements that can conduct electricity) and some properties of nonmetals (elements that cannot conduct electricity). For example, most metalloids can conduct electricity, but not as well as metals. Metalloids also tend to be shiny like metals, but brittle like nonmetals. Chemically, metalloids may behave like metals or nonmetals, depending on their number of valence electrons. Q: Why does the chemical behavior of an element depend on its number of valence electrons? A: Valence electrons are the electrons in an atoms outer energy level that may be involved in chemical reactions with other atoms. Group 13 of the periodic table is also called the boron group because boron (B) is the first element at the top of the group (see Figure 1.2). Boron is also the only metalloid in this group. The other four elements in the groupaluminum (Al), gallium (Ga), indium (In), and thallium (Tl)are all metals. Group 13 elements have three valence electrons and are fairly reactive. All of them are solids at room temperature. Group 14 of the periodic table is headed by the nonmetal carbon (C), so this group is also called the carbon group. Carbon is followed by silicon (Si) and germanium (Ge) (Figure 1.3), which are metalloids, and then by tin (Sn) and lead (Pb), which are metals. Group 14 elements group have four valence electrons, so they generally arent very reactive. All of them are solids at room temperature. Group 15 of the periodic table is also called the nitrogen group. The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Arsenic (As) (Figure 1.4) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they Germanium is a brittle, shiny, silvery- white metalloid. Along with silicon, it is used to make the tiny electric cir- cuits on computer chips. It is also used to make fiber optic cableslike the one pictured herethat carry telephone and other communication signals. vary in their reactivity. Nitrogen, for example, is not very reactive at all, whereas phosphorus is very reactive and found naturally only in combination with other substances. All group 15 elements are solids, except for nitrogen, which is a gas. Group 16 of the periodic table is also called the oxygen group. The first three elementsoxygen (O), sulfur (S), and selenium (Se)are nonmetals. They are followed by tellurium (Te) (Figure 1.5), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive. Oxygen is a gas at room temperature, and the other elements in the group are solids. Q: With six valence electrons, group 16 elements need to attract two electrons from another element to have a stable electron arrangement of eight valence electrons. Which group of elements in the periodic table do you think might The most common form of the metalloid arsenic is gray and shiny. Arsenic is extremely toxic, so it is used as rat poison.

Context: Protists are placed in the Protist Kingdom. This kingdom is one of four kingdoms in the Eukarya domain. The other three Eukarya kingdoms are the Fungi, Plant, and Animal Kingdoms. The Protist Kingdom is hard to define. It includes many different types of organisms. You can see some examples of protists in Figure 9.1. The Protist Kingdom includes all eukaryotes that dont fit into one of the other three eukaryote kingdoms. For that reason, its sometimes called the trash can kingdom. The number of species in the Protist Kingdom is unknown. It could range from as few as 60,000 to as many as 200,000 species. For a beautiful introduction to the amazing world of protists, watch this video: MEDIA Click image to the left or use the URL below. URL: Scientists think that protists are the oldest eukaryotes. If so, they must have evolved from prokaryotes. How did this happen? How did cells without organelles acquire them? What was the origin of mitochondria, chloroplasts, and other organelles? The most likely way organelles evolved is shown in Figure 9.2. First, smaller prokaryotic cells invaded, or were engulfed by, larger prokaryotic cells. The smaller cells benefited by getting nutrients and a safe place to live. The larger cells benefited by getting some of the organic molecules or energy released by the smaller cells. Eventually, the smaller cells evolved into organelles in the larger cells. After that, neither could live without the other. Despite the diversity of protists, they do share some traits. The cells of all protists have a nucleus. They also have other membrane-bound organelles. For example, all of them have mitochondria, and some of them have chloroplasts. Most protists consist of a single cell. Some are multicellular but they lack specialized cells. Most protists live in wet places. They are found in oceans, lakes, swamps, or damp soils. Many protists can move. Most protists also have a complex life cycle. The life cycle of an organism is the cycle of phases it goes through until it returns to the starting phase. The protist life cycle includes both sexual and asexual reproduction. Why reproduce both ways? Each way has benefits. Asexual reproduction is fast. It allows rapid population growth when conditions are stable. Sexual reproduction increases genetic variation. This helps ensure that some organisms will survive if conditions change. Protists are classified based on traits they share with other eukaryotes. There are animal-like, plant-like, and fungus- like protists. The three groups differ mainly in how they get carbon and energy. Animal-like protists are called protozoa (protozoan, singular). Most protozoa consist of a single cell. Protozoa are probably ancestors of animals. Protozoa are like animals in two ways: 1. Protozoa are heterotrophs. Heterotrophs get food by eating other organisms. Some protozoa prey on bacteria. Some are parasites of animals. Others graze on algae. Still others are decomposers that break down dead organic matter. 2. Almost all protozoa can move. They have special appendages for this purpose. You can see different types in Figure 9.3. Cilia (cilium, singular) are short, hair-like projections. Pseudopods are temporary extensions of the cytoplasm. Flagella are long, whip-like structures. Flagella are also found in most prokaryotes. Plant-like protists are commonly called algae (alga, singular). Some algae consist of single cells. They are called diatoms. Other algae are multicellular. An example is seaweed. Seaweed called kelp can grow as large as trees. You can see both a diatom and kelp in Figure 9.4. Algae are probably ancestors of plants. Algae are like plants mainly because they contain chloroplasts. This allows them to make food by photosynthesis. Algae are important producers in water-based ecosystems such as the ocean. On the other hand, algae lack other plant structures. For example, they dont have roots, stems, or leaves. Also unlike plants, some algae can move. They may move with pseudopods or flagella. Fungus-like protists include slime molds and water molds, both shown in Figure 9.5. They exist

Context: In 1982, in New Jersey, Gracie (Mary Ashleigh Green) is in a school playground where one boy is bullying another. She steps in and beats up the bully to help the victim, a boy she likes. But instead of being grateful, he feels humiliated at being rescued "by a girl," and gets angry at her. She promptly punches him in the nose and then sulks alone in the playground. Fast-forward to the present day, and Gracie Hart (Sandra Bullock) is an FBI Special Agent. In the middle of an operation against Russian mobsters, the target starts to choke on some food, and Gracie disobeys her superior's command in order to prevent the target from choking. As a result, a member of her squad gets shot, and she is reprimanded by being reassigned to a desk job. Soon afterwards, the bureau learns that there has been a bomb threat against the 75th annual Miss United States beauty pageant in San Antonio, Texas, which the bureau determines came from the notorious domestic terrorist known as "The Citizen". Gracie's partner, Special Agent Eric Matthews (Benjamin Bratt), is chosen to lead the mission to prevent the attack. Despite Eric's position as a lead agent in charge, it is apparent that Gracie is the more capable agent, as Eric is unsure of how to proceed and takes credit for Gracie's suggestions. One of Gracie's suggestions is to put an agent undercover at the pageant. Gracie's male colleagues then proceed to have a bit of fun running the digital images of female and male agents through a website meant for children to play dress up with their dolls. Despite the immature and chauvinistic actions of the agents, Eric recognizes that Gracie is the female FBI agent best qualified for the undercover job. Beauty pageant coach Victor Melling (Michael Caine), whose reputation was ruined after his last contestant criticized his methods, teaches the tomboyish Gracie how to dress, walk, and act like a contestant. She is not used to such behavior, however, and sees the pageant and its participants as "antifeminist ". Eventually though Victor and Gracie come to respect each other's strengths. Representing New Jersey as "Gracie Lou Freebush", Gracie impresses the audience by playing the glass harp and demonstrating self-defense techniques during the talent competition. She also unexpectedly becomes friends with the other contestants, in particular Miss Rhode Island, Cheryl Frasier (Heather Burns) Several suspects emerge, including the corrupt competition director and former pageant winner Kathy Morningside (Candice Bergen); her unpleasant assistant Frank Tobin (Steve Monroe); the veteran pageant MC Stan Fields (William Shatner) who, like Kathy, is being replaced with a younger person; and last but not least Cheryl, who appears to have a history as a radical animal rights activist. While Gracie takes Cheryl and some of the other girls out partying, in an attempt to seek out more information about Cheryl's past through "girl talk", The Citizen is arrested elsewhere on an unrelated charge. After hearing what some of the other contestants said about Kathy Morningside's past (she won the pageant only after the original winner "mysteriously" contracted food poisoning), Gracie begins to suspect her, and is worried about the safety of the girls. Her boss thinks that her suspicions are groundless and that the pageant is out of danger now that the Citizen has been arrested. He calls off the mission. Gracie opts to turn in her badge and gun and continue the investigation alone. Eric initially fails to support Gracie and is about to return to the bureau when he figures out that Gracie's suspicions must be correct, and returns to help her. In the final round of the pageant, Gracie earns 1st Runner up while Cheryl becomes Miss United States. Gracie realizes that Kathy Morningside and Frank Tobin unknown to anyone (except Victor) is Kathy's son impersonated "The Citizen" and made the threat. Because she was going to be fired after the pageant was over, Kathy and her son were planning to murder the newly crowned pageant winner on stage by putting an explosive device in her

In 1975, after Hustler publishes nude pictures of former first lady Jackie Kennedy Onassis, sales take off.Flynt becomes smitten with Althea Leasure (Courtney Love), a stripper who works at one of his clubs. With Althea and Jimmy's help, Flynt makes a fortune from sales of Hustler. With his success comes enemies - as he finds himself a hated figure of anti-pornography activists. He argues with the activists, saying that "murder is illegal, but if you take a picture of it you may get your name in a magazine or maybe win a Pulitzer Prize". "However", he continues, "sex is legal, but if you take a picture of that act, you can go to jail". He becomes involved in several prominent court cases, and befriends a young lawyer, Alan Isaacman (Edward Norton). In 1975, Flynt loses a smut-peddling court decision in Cincinnati but is released from jail soon afterwards on a technicality. Ruth Carter Stapleton (Hanover), a Christian activist and sister of President Jimmy Carter, seeks out Flynt and urges him to give his life to Jesus. Flynt seems moved and starts letting his newfound religion influence everything in his life, including Hustler content.In 1978, during another trial in Georgia, Flynt and Isaacman are both shot by a man with a rifle while they walk outside a courthouse. Isaacman recovers, but Flynt is paralyzed from the waist down and uses a wheelchair for the rest of his life. Wishing he was dead, Flynt renounces God. Because of the emotional and physical pain, he moves to Beverly Hills, California and spirals down into depression and drug use. During this time, Althea also becomes addicted to painkillers and morphine.In 1983, Flynt undergoes back surgery to deaden several nerves, and as a result, feels rejuvenated. He returns to an active role with the publication, which, in his absence, had been run by Althea and Jimmy. That same year, Flynt is soon in court again for leaking videos relating to the John DeLorean entrapment case, and during his courtroom antics, he fires Isaacman, then throws an orange at the judge. He later wears an American flag as an adult diaper along with an army helmet, and wears T-shirts with provocative messages such as "I Wish I Was Black" and "Fuck This Court." After spitting water at the judge Flynt is sent to a psychiatric ward, where he sinks into depression again. He is diagnosed with having bipolar disorder and forced to take treatment.During this time, Flynt publishes a satirical parody ad in which Christian fundamentalist preacher Jerry Falwell tells of a sexual encounter with his mother. Falwell sues for libel and emotional distress. Flynt countersues for copyright infringement, because Falwell copied his ad. The case goes to trial in December 1984, but the decision is mixed, as Flynt is found guilty of inflicting emotional distress but not libel.By that time, Althea has contracted HIV, which proceeds to AIDS. Some time later in 1987, Flynt finds her dead in the bathtub, having drowned. Flynt presses Isaacman to appeal the Falwell decision to the Supreme Court of the United States. Isaacman refuses, saying Flynt's courtroom antics humiliated him. Flynt pleads with him, saying that he "wants to be remembered for something meaningful". Isaacman agrees and argues the "emotional distress" decision in front of the Supreme Court, in the case Hustler Magazine v. Falwell in 1988. With Flynt in the courtroom, the court overturns the original verdict in a unanimous decision. After the trial, Flynt is alone in his bedroom watching old videotapes of a healthy Althea.

Context: Organisms that live in lakes, ponds, streams, springs or wetlands are part of freshwater ecosystems. These ecosys- tems vary by temperature, pressure (in lakes), the amount of light that penetrates and the type of vegetation that lives there. Limnology is the study of bodies of fresh water and the organisms that live there. A lake has zones just like the ocean. The ecosystem of a lake is divided into three distinct zones (Figure 1.1): 1. The surface (littoral) zone is the sloped area closest to the edge of the water. 2. The open-water zone (also called the photic or limnetic zone) has abundant sunlight. 3. The deep-water zone (also called the aphotic or profundal zone) has little or no sunlight. There are several life zones found within a lake: In the littoral zone, sunlight promotes plant growth, which provides food and shelter to animals such as snails, insects, and fish. In the open-water zone, other plants and fish, such as bass and trout, live. The deep-water zone does not have photosynthesis since there is no sunlight. Most deep-water organisms are scavengers, such as crabs and catfish that feed on dead organisms that fall to the bottom of the lake. Fungi and bacteria aid in the decomposition in the deep zone. Though different creatures live in the oceans, ocean waters also have these same divisions based on sunlight with similar types of creatures that live in each of the zones. The three primary zones of a lake are the littoral, open-water, and deep-water zones. Wetlands are lands that are wet for significant periods of time. They are common where water and land meet. Wetlands can be large flat areas or relatively small and steep areas. Wetlands are rich and unique ecosystems with many species that rely on both the land and the water for survival. Only specialized plants are able to grow in these conditions. Wetlands tend have a great deal of biological diversity. Wetland ecosystems can also be fragile systems that are sensitive to the amount and quality of water present within them. Click image to the left or use the URL below. URL: Marshes are shallow wetlands around lakes, streams, or the ocean where grasses and reeds are common, but trees are not (Figure 1.2). Frogs, turtles, muskrats, and many varieties of birds are at home in marshes. A salt marsh on Cape Cod in Mas- sachusetts. A swamp is a wetland with lush trees and vines found in low-lying areas beside slow-moving rivers (Figure 1.3). Like marshes, they are frequently or always inundated with water. Since the water in a swamp moves slowly, oxygen in the water is often scarce. Swamp plants and animals must be adapted for these low-oxygen conditions. Like marshes, swamps can be fresh water, salt water, or a mixture of both. As mentioned above, wetlands are home to many different species of organisms. Although they make up only 5% of the area of the United States, wetlands contain more than 30% of the plant types. Many endangered species live in wetlands, so wetlands are protected from human use. Wetlands also play a key biological role by removing pollutants from water. For example, they can trap and use fertilizer that has washed off a farmers field, and therefore they prevent that fertilizer from contaminating another body of water. Since wetlands naturally purify water, preserving wetlands also helps to maintain clean supplies of water.

Context: The film begins some years in the future from this exact moment. We see ads everywhere (buildings, walls, bus stops, e.t.c) for the hit game Slayers, and how the star character Kable (Gerard Butler) has four battles left before he earns his freedom. We are then shown a battle in progress: a massive shootout inside a factory. Everyone in the game is controlled by players elsewhere. Characters get points for each kill and for saving a teammate. Some characters are shown to be doing menial tasks in the battlefield, seemingly unaware of all the violence around them. 17-year-old Simon (Logan Lerman) plays/controls Kable and leads him around the factory. After slaughtering most everyone in his way, Kable gets blasted outside of the factory. Kable manages to run to the safe point to win the battle. Afterward, the surviving characters are transported elsewhere. The other characters congratulate Kable on winning, since he now only has three battles left until freedom. Some of the other characters don't believe that anyone will be released from the game.The producer (Michael Weston) and Chief of Staff, Bob, (John de Lancie) for the Gina Parker Smith Show discuss their next guest for the show - genius recluse Ken Castle, the creator of Slayers. On the show, Gina (Kyra Sedgwick) talks about the achievements of Ken Castle (Michael C. Hall). He first created a game called Society, which is basically a Sims game but instead of controlling a fake character, the players control a real person and can make them do whatever they want. You can pay to control someone else, or you can get paid to be controlled. Society quickly became extremely popular and profitable, making Castle the richest person in the universe. Nine months ago Castle created Slayers, a controversial game which is supported by the federal government. Castle defends Slayers by stating that each character in the game, though they are real people, are all death row inmates who chose to sign up for the game instead of doing their prison sentence. If a convict can stay alive for thirty battles, they will be set free (though no one has ever survived that long). Some convicts are sent into battlefields with pre-engineered actions to do, and will be set free if they survive just one battle, but are unable to defend themselves (which makes their death rate extremely high). Also, the games are all televised on pay-per-view. Everyone in Slayers and Society has had nano-cells implanted into their brains, which makes it possible for them to be controlled by someone else. They can only be controlled in the perimeter of the game (meaning after the game is over, they get their control back).After the show is over, the signal is hacked into by Humanz, a resistance group. The Humanz Brother (Ludacris) condemns Castle and states that eventually we will all be his slaves if we continue down this road. Castle gets a kick out of it and has his men try to locate where the signal came from. In prison, a convict beats a guard to death and tries to escape but in the end, he fails. Kable sits by himself and thinks about his family. Freek (John Leguizamo) sits next to Kable. He talks about how Kable spooks everyone else when he sits by himself and is constantly thinking. He can't believe that Kable only has three battles left. Freek asks him why he's in prison. Kable has a quick flashback of a man bleeding in a room. Later on, while sitting in his cell, someone opens the slot of the door and hands Kable a picture of his wife and child. The female voice on the other side knows that his family is the only thing he fights for. She makes Kable sign an autograph for her son, David, and then takes a blood sample from his hand as proof of authenticity to increase the value of the autograph.Elsewhere, we see Kable's wife Angie (Amber Valletta) going to work as a character in Society. Practically all the game characters are dressed in ridiculous and skimpy costumes

Context: A rock is a naturally formed, non-living Earth material. Rocks are made of collections of mineral grains that are held together in a firm, solid mass (Figure 1.1). How is a rock different from a mineral? Rocks are made of minerals. The mineral grains in a rock may be so tiny that you can only see them with a microscope, or they may be as big as your fingernail or even your finger (Figure Rocks are identified primarily by the minerals they contain and by their texture. Each type of rock has a distinctive set of minerals. A rock may be made of grains of all one mineral type, such as quartzite. Much more commonly, rocks are made of a mixture of different minerals. Texture is a description of the size, shape, and arrangement of mineral grains. Are the two samples in Figure 1.3 the same rock type? Do they have the same minerals? The same texture? The different colors and textures seen in this rock are caused by the presence of different minerals.

Sample 2 Crystals are tiny or microscopic Magma erupted and cooled quickly Andesite As seen in Table 1.1, these two rocks have the same chemical composition and contain mostly the same minerals, but they do not have the same texture. Sample 1 has visible mineral grains, but Sample 2 has very tiny or invisible grains. The two different textures indicate different histories. Sample 1 is a diorite, a rock that cooled slowly from magma (molten rock) underground. Sample 2 is an andesite, a rock that cooled rapidly from a very similar magma that erupted onto Earths surface. A few rocks are not made of minerals because the material they are made of does not fit the definition of a mineral. Coal, for example, is made of organic material, which is not a mineral.

Context: Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown. "There's so much to learn," he'd say. "Though we're born stupid, only the stupid remain that way. " He was determined that none of his children would be denied an education. Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point. Then came the moment--the time to share the day's new learning. Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen. "Felice," he'd say, "tell me what you learned today. " "I learned that the population of Nepal is .... " Silence. Papa was thinking about what was said, as if the salvation of the world would depend upon it. "The population of Nepal. Hmm. Well . . . . " he'd say. "Get the map; let's see where Nepal is. " And the whole family went on a search for Nepal. This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts. As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another's education. And by looking at us, listening to us, respecting our input, affirming our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher. Later during my training as a future teacher /1 studied with some of the most famous educators. They were imparting what Papa had known all along--the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.

Context: Restless legs syndrome/Willis-Ekbom disease (RLS/WED) is commonly seen in patients with end-stage renal disease (ESRD), but this condition has not been properly recognized. The prevalence of RLS/WED in ESRD shows the ethnic variation (7%-68%), with the similar tendency of primary RLS/WED. Although RLS/WED in ESRD is defined in secondary RLS/WED, the factors of ESRD that are involved in the genesis of RLS/WED remain unknown. Even after renal transplantation, RLS/WED symptoms do not completely disappear, and genetic predisposition to RLS/WED may play an important role in causing RLS/WED. Long-term intervention for RLS/WED and ESRD will be necessary.

Context: Converging plates can be oceanic, continental, or one of each. If both are continental they will smash together and form a mountain range. If at least one is oceanic, it will subduct. A subducting plate creates volcanoes. In the chapter Plate Tectonics we moved up western North America to visit the different types of plate boundaries there. Locations with converging in which at least one plate is oceanic at the boundary have volcanoes. Melting at convergent plate boundaries has many causes. The subducting plate heats up as it sinks into the mantle. Also, water is mixed in with the sediments lying on top of the subducting plate. As the sediments subduct, the water rises into the overlying mantle material and lowers its melting point. Melting in the mantle above the subducting plate leads to volcanoes within an island or continental arc. Volcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Trenches mark subduction zones, although only the Aleutian Trench and the Java Trench appear on the map in the previous concept, "Volcano Characteristics." The Cascades are a chain of volcanoes at a convergent boundary where an oceanic plate is subducting beneath a continental plate. Specifically the volcanoes are the result of subduction of the Juan de Fuca, Gorda, and Explorer Plates beneath North America. The volcanoes are located just above where the subducting plate is at the right depth in the mantle for there to be melting (Figure 1.1). The Cascades have been active for 27 million years, although the current peaks are no more than 2 million years old. The volcanoes are far enough north and are in a region where storms are common, so many are covered by glaciers. At divergent plate boundaries hot mantle rock rises into the space where the plates are moving apart. As the hot mantle rock convects upward it rises higher in the mantle. The rock is under lower pressure; this lowers the melting temperature of the rock and so it melts. Lava erupts through long cracks in the ground, or fissures. Volcanoes erupt at mid-ocean ridges, such as the Mid-Atlantic ridge, where seafloor spreading creates new seafloor in the rift valleys. Where a hotspot is located along the ridge, such as at Iceland, volcanoes grow high enough to create islands (Figure 1.3). Eruptions are found at divergent plate boundaries as continents break apart. The volcanoes in Figure 1.4 are in the East African Rift between the African and Arabian plates. Remember from the chapter Plate Tectonics that Baja California is being broken apart from mainland Mexico as another example of continental rifting. Click image to the left or use the URL below.

Context: Did you ever make a secret code? One way to make a code is to represent each letter of the alphabet by a different number. Then you can send a coded message by writing words as strings of digits. This is similar to how information is encoded using an electric current. The voltage of the current is changed rapidly and repeatedly to encode a message, called an electronic signal. There are two different types of electronic signals: analog signals and digital signals. Both are illustrated in Figure 23.20. A digital signal consists of pulses of voltage, created by repeatedly switching the current off and on. This type of signal encodes information as a string of 0s (current off) and 1s (current on). This is called a binary ("two-digit") code. DVDs, for example, encode sounds and pictures as digital signals. An analog signal consists of continuously changing voltage in a circuit. For example, microphones encode sounds as analog signals. Electronic components are the parts used in electronic devices such as computers. The components transmit and change electric current. They are made of materials called semiconductors. A semiconductor is a solid crystalusually consisting mainly of siliconthat can conduct current better than an electric insulator but not as well as an electric conductor. Very small amounts of other elements, such as boron or phosphorus, are added to the silicon so it can conduct current. A semiconductor is illustrated in Figure 23.21. There are two different types of semiconductors: n-type and p-type. An n-type semiconductor consists of silicon and an element such as phosphorus that gives the silicon crystal extra electrons. An n-type semiconductor is like the negative terminal in a chemical cell. A p-type semiconductor consists of silicon and an element such as boron that gives the silicon positively charged holes where electrons are missing. A p-type semiconductor is like the positive terminal in a chemical cell. Electronic components contain many semiconductors. Types of components include diodes, transistors, and inte- grated circuits. Each type is described in Table 23.2. Electronic Component Diode Transistor Integrated Circuit (Microchip) Description A diode consists of a p-type and an n-type semicon- ductor placed side by side. When a diode is connected by leads to a source of voltage, electrons flow from the n-type to the p-type semiconductor. This is the only direction that electrons can flow in a diode. This makes a diode useful for changing alternating current to direct current. A transistor consists of three semiconductors, either p- n-p or n-p-n. Current cant flow through a transistor unless a small amount of current is applied to the center semiconductor (through the base). Then a much larger current can flow through the transistor from end to end (from collector to emitter). This means that a transmitter can be used as a switch, with pulses of a small current turning a larger current on and off. A transistor can also be used to increase the amount of current flowing through a circuit. You can learn more about transistors and how they work at this URL: http An integrated circuitalso called a microchipis a tiny, flat piece of silicon that consists of layers of elec- tronic components such as transistors. An integrated circuit as small as a fingernail can contain millions of electronic components. Current flows extremely rapidly in an integrated circuit because it doesnt have far to travel. You can learn how microprocessors are made at this URL: Many of the devices you commonly use are electronic. Electronic devices include computers, mobile phones, TV remotes, DVD and CD players, game systems, MP3 players, and digital cameras. All of these devices use electric current to encode, analyze, or transmit information. Consider the computer as an example of an electronic device. A computer contains microchips with millions of tiny electronic components. Information is encoded as 0s and 1s and transmitted as electrical pulses. One digit (either 0 or 1) is called a bit, which stands for "binary digit." Each group of eight digits is called a byte. A gigabyte is a billion bytes that

Context: Protein-protein interactions are essential for many cellular processes. We have developed a technology called light-activated dimerization (LAD) to artificially induce protein hetero- and homodimerization in live cells using light. Using the FKF1 and GIGANTEA (GI) proteins of Arabidopsis thaliana, we have generated protein tags whose interaction is controlled by blue light. We demonstrated the utility of this system with LAD constructs that can recruit the small G-protein Rac1 to the plasma membrane and induce the local formation of lamellipodia in response to focal illumination. We also generated a light-activated transcription factor by fusing domains of GI and FKF1 to the DNA binding domain of Gal4 and the transactivation domain of VP16, respectively, showing that this technology is easily adapted to other systems. These studies set the stage for the development of light-regulated signaling molecules for controlling receptor activation, synapse formation and other signaling events in organisms.

Context: The film depicts the construction and ultimate demolition of a metaphorical wall. Though the film's symbolism is open to interpretation, the wall itself clearly reflects a sense of isolation and alienation.Pink (Bob Geldof), the protagonist (and unreliable narrator) of the film, is a rock star, one of several reasons behind his apparent depressive and detached emotional state. He is first seen in a quiet hotel room, having trashed it. The opening music is not by Pink Floyd, but is the Vera Lynn recording of "The Little Boy that Santa Claus Forgot". During the following scenes, it is revealed that Pink's father, a British soldier, was killed in action during World War II during Pink's infancy. The reference is almost certainly to the death of Roger Waters' real-life father, Eric Fletcher Waters, who died in combat in Italy during Operation Shingle (the Battle of Anzio) in February 1944.The movie then flashes back to Pink as a young English boy growing up in the early 1950s. Throughout his childhood, Pink longs for a father figure after he learns his father died in the war. At school, he is humiliated by his mean and stern teacher for writing poems in class. The poems that the teacher seizes from him and reads aloud are lyrics from "Money" from the Pink Floyd album Dark Side of the Moon. Pink is also affected by his overprotective mother who spoils him by giving him whatever he wants.As an adult, Pink eventually gets married as his fame as a rock star grows, but he and his wife grow apart and she has an affair while Pink is on tour. When Pink learns of the affair, he compensates with expensive materialistic possessions and turns to a willing groupie (Jenny Wright), whom he brings back to his hotel room only to trash it in a fit of violence, causing her to flee the room in terror.Pink slowly begins to lose his mind to metaphorical "worms". He shaves off all of his body hair (an incident inspired by former bandmate Syd Barrett, who appeared at a 1975 recording session of Wish You Were Here, having shaved his eyebrows and body hair) and, while watching The Dam Busters on television, morphs into his neo-Nazi alter-ego. Pink's manager (Bob Hoskins), along with the hotel manager (Michael Ensign) and some paramedics, break into the hotel room and discover Pink. They take him away into a waiting limousine outside the hotel and inject him with drugs to enable him to perform.The drugs cause Pink to hallucinate and he fantasises that he is a neo-Nazi dictator, his concert is a rally. His followers proceed to attack ethnic minorities and rape the white girlfriend of a black man. Later, Pink holds a rally in suburban London, singing "Waiting for the Worms". The scene is inter-cut by images of animated marching hammers that goose-step across ruins.Pink screams "Stop!" and takes refuge in a bathroom stall at the concert venue, reciting poems which would later be used as lyrics on Pink Floyd's "Your Possible Pasts" from The Final Cut album and "5:11 AM (The Moment Of Clarity)" from Roger Waters' The Pros and Cons of Hitch Hiking.In a climatic animated sequence, Pink puts himself on trial. He is depicted as a small, pink rag doll that rarely moves. The judge is a giant pair of buttocks, with two backward facing legs, an anus for a mouth and a scrotum for a chin. The lawyer is a tall, menacing, vulturelike man and the schoolmaster is an abusive, hateful marionette. After hearing from the parties and witnesses (Pink's wife and mother), the judge orders the wall to be torn down. The wall explodes and shows a montage of events from the entire film.The film concludes with three children cleaning up a pile of debris after an earlier riot. It is unknown whatever has happened to Pink, leaving the viewer to decide.

Context: Mitogen-activated protein kinase (MAPK) cascades are involved in the regulation of cellular proliferation, differentiation, survival, apoptosis, as well as in inflammatory responses. Signal intensity and duration have been recognized as crucial parameters determining MAPK signaling output. Phosphatases play a particularly important role in this respect, by tightly controlling MAPK phosphorylation and activation. M3/6 (DUSP8) is a dual-specificity phosphatase implicated in the dephosphorylation and inactivation of JNK and, to a lesser extent, p38 MAPKs and is found in a complex with these kinases, along with other pathway components, held together by scaffold proteins. The JNK family consists of three genes, giving rise to at least ten different splice variants. Some functional differences between these gene products have been demonstrated, but the underlying molecular mechanisms and the roles of individual splice variants are still incompletely understood. We have investigated the interaction of M3/6 with JNK isoforms, as well as scaffold proteins of the JNK interacting protein (JIP) family, in order to elucidate the contribution of M3/6 to the regulation of distinct JNK signaling modules. M3/6 exhibited stronger binding towards JNK1 and JNK2 isoforms and this was reflected in higher enzymatic activity towards JNK22 when compared to JNK11 in vitro. After activation of the pathway by exposure of cells to arsenite, the interaction of M3/6 with JNK1 and JNK3 was enhanced, whereas that with JNK1 or JNK2 decreased. The modulation of binding affinities was found to be independent of JNK-mediated M3/6 phosphorylation. Furthermore, arsenite treatment resulted in an inducible recruitment of M3/6 to JNK-interacting protein 3 (JIP3) scaffold complexes, while its interaction with JIP1 or JIP2 was constitutive. The presented data suggest an isoform-specific role for the M3/6 phosphatase and the dynamic targeting of M3/6 towards distinct JNK-containing signaling complexes.

Context: The Fox River flows from north to south in its first section. The Upper Fox River begins as a small stream northeast of Pardeeville. It flows southwest towards Portage and comes within 2 miles of the Wisconsin River before turning north. After flowing past Montello, the river goes northeast until reaching Lake Butte des Morts. Here it is joined by the tributary Wolf River before entering the west side of Lake Winnebago at Oshkosh. The Upper Fox flows for a total of 142 miles . The Lower Fox begins at the north end of Lake Winnebago, where it flows north past Neenah, Menasha, and Appleton as it begins its 40-mile course northeast towards Lake Michigan. The river drops around 164 feet over this short stretch. Prior to the construction of European-style dams after 1850, the river had many sizable rapids. The Lower Fox ends after flowing through the city of Green Bay and into Lake Michigan through Green Bay. Altogether, the Fox-Wolf watershed drains an area of about 6,429 square miles , giving the Fox an average discharge rate of 4132ft3/s into the bay.

Context: In the 19th century, a Grande Dame (Jeanne Moreau) summons The Brothers Grimm to her palace, where the brothers discuss their interpretation of the Cinderella story and notice a painting displayed in the room. The Grande Dame shows the brothers a glass slipper and tells them the story of Danielle de Barbarac, the true story of Cinderella. In 16th-century France, widower Auguste de Barbarac (Jeroen Krabbe), father of eight-year-old Danielle, marries Rodmilla de Ghent (Anjelica Huston), a wealthy baroness with two young daughters, Marguerite and Jacqueline, but he dies of a heart attack shortly afterwards. Before dying, Auguste's last words are directed to Danielle, which causes the Baroness to envy Danielle and treat her miserably for the next ten years. While Marguerite (Megan Dodds) is hostile and cruel to Danielle, Jacqueline (Melanie Lynskey) is kinder and more respectful to her, though she often stays out of the crossfires to keep the peace. By the time Danielle (Drew Barrymore) is eighteen, the estate has fallen into decline, as the Baroness has no interest in farming and wishes to get back to court as soon as possible. Danielle has been reduced to a servant in her own home, waiting on her stepmother and stepsisters, and clinging to her father's last gift, a copy of Thomas More's Utopia. While collecting apples, Danielle sees a man stealing her father's horse and unseats him with an apple. When she recognizes he is Prince Henry (Dougray Scott), she abases herself. He gives her a bag of gold in exchange for her silence. She decides to use the money to rescue their servant, Maurice (Walter Sparrow), whom the Baroness has sold to pay her debts. Henry's escape from the duties of court is foiled when he encounters a band of gypsies robbing an old man. He learns that the old man is Leonardo da Vinci (Patrick Godfrey), who has been summoned to court. Henry chases a thief and returns the Mona Lisa to da Vinci, then returns with him. Meanwhile, Danielle dresses as a noblewoman and leaves to buy back Maurice, but the guards refuse, saying he is being deported to the Americas. She argues for his release and, when Henry overhears, he orders Maurice's release. Intrigued by Danielle's mysterious identity, and amazed by her eloquence and passionate pleas, he begs for her name. Danielle gives Henry the name of her mother, "Comtesse Nicole de Lancret", who died giving birth to Danielle. King Francis (Timothy West) and Queen Marie (Judy Parfitt) tell Henry that he must choose a bride before the upcoming masquerade ball, or he will have to wed the Spanish princess Gabriella. All the noble families receive an invitation and Danielle initially believes she is included. When collecting truffles, she meets Henry by the river in the company of da Vinci. Henry and Danielle engage in a lively debate before Danielle runs off after she notices Jacqueline searching for her. Henry invites her to visit the library of a nearby monastery. On the way home, they are ambushed by the gypsies, who are amused by Danielle's outrage and agree to release her with whatever she can carry. When she picks up Henry and begins to walk away, the gypsies offer them a horse. Henry and Danielle spend the night at the gypsy camp, sharing their first kiss and arranging to meet again. The next morning, Danielle catches the Baroness and Marguerite stealing her mother's dress and slippers for Marguerite to wear to the ball. After Marguerite insults Danielle about her mother's death, she punches Marguerite in the face and chases her around the manor until Marguerite threatens to throw Utopia into the fireplace. Danielle returns her mother's slippers to the Baroness in exchange for the book but Marguerite burns it in the fire anyway in an act of spite. After Danielle is punished by whipping, Jacqueline tends to her wounds and condemns Marguerite for insulting Danielle's deceased mother. When Danielle meets Henry later, she wishes to tell him the truth, but is afraid he will reject her after he confesses his love. During

Context: Vitamins and minerals are also nutrients. They do not provide energy, but they are needed for good health. Vitamins are organic compounds that the body needs in small amounts to function properly. Humans need 13 different vitamins. Some of them are listed below ( Table 1.1). The table also shows how much of each vitamin you need every day. Vitamins have many roles in the body. For example, Vitamin A helps maintain good vision. Vitamin B9 helps form red blood cells. Vitamin K is needed for blood to clot when you have a cut or other wound. Vitamin Necessary for Available from Daily Amount Required (at ages 913 years) Vitamin Necessary for Available from A Good vision B1 Healthy nerves B3 Healthy skin and nerves B9 Red blood cells B12 Healthy nerves C Growth and repair of tis- sues Healthy bones and teeth Blood to clot Carrots, spinach, milk, eggs Whole wheat, peas, meat, beans, fish, peanuts Beets, liver, pork, turkey, fish, peanuts Liver, peas, dried beans, leafy green vegetables Meat, liver, milk, shell- fish, eggs Oranges, grapefruits, red peppers, broccoli Milk, salmon, tuna, eggs Spinach, brussels sprouts, milk, eggs D K Daily Amount Required (at ages 913 years) 600 g (1 g = 1 106 g) 0.9 mg (1 mg = 1 103 g) 12 mg 300 g 1.8 g 45 mg 5 g 60 g Some vitamins are produced in the body. For example, vitamin D is made in the skin when it is exposed to sunlight. Vitamins B12 and K are produced by bacteria that normally live inside the body. Most other vitamins must come from foods. Foods that are good sources of vitamins include whole grains, vegetables, fruits, and milk ( Table 1.1). Not getting enough vitamins can cause health problems. For example, too little vitamin C causes a disease called scurvy. People with scurvy have bleeding gums, nosebleeds, and other symptoms. Minerals are chemical elements that are needed for body processes. Minerals that you need in relatively large amounts are listed below ( Table 1.2). Minerals that you need in smaller amounts include iodine, iron, and zinc. Minerals have many important roles in the body. For example, calcium and phosphorus are needed for strong bones and teeth. Potassium and sodium are needed for muscles and nerves to work normally. Mineral Necessary for Available from Calcium Strong bones and teeth Chloride Magnesium Proper balance of water and salts in body Strong bones Phosphorus Strong bones and teeth Potassium Muscles and nerves to work normally Muscles and nerves to work normally Milk, soy milk, leafy green vegetables Table salt, most packaged foods Whole grains, leafy green vegetables, nuts Meat, poultry, whole grains Meats, grains, bananas, orange juice Table salt, most packaged foods Sodium Daily Amount Required (at ages 913 years) 1,300 mg 2.3 g 240 mg 1,250 mg 4.5 g 1.5 g Your body cannot produce any of the minerals that it needs. Instead, you must get minerals from the foods you eat. Good sources of minerals include milk, leafy green vegetables, and whole grains ( Table 1.2). Not getting enough minerals can cause health problems. For example, too little calcium may cause osteoporosis. This is a disease in which bones become soft and break easily. Getting too much of some minerals can also cause health problems. Many people get too much sodium. Sodium is added to most packaged foods. People often add more sodium to their food by using table salt. Too much sodium causes high blood pressure in some people.

Context: The Sun and all the objects that are held by the Suns gravity are known as the solar system. These objects all revolve around the Sun. The ancient Greeks recognized five planets. These lights in the night sky changed their position against the background of stars. They appeared to wander. In fact, the word planet comes from a Greek word meaning wanderer. These objects were thought to be important, so they named them after gods from their mythology. The names for the planets Mercury, Venus, Mars, Jupiter, and Saturn came from the names of gods and a goddess. The ancient Greeks thought that Earth was at the center of the universe, as shown in Figure 25.1. The sky had a set of spheres layered on top of one another. Each object in the sky was attached to one of these spheres. The object moved around Earth as that sphere rotated. These spheres contained the Moon, the Sun, and the five planets they recognized: Mercury, Venus, Mars, Jupiter, and Saturn. An outer sphere contained all the stars. The planets appear to move much faster than the stars, so the Greeks placed them closer to Earth. Ptolemy published this model of the solar system around 150 AD. About 1,500 years after Ptolemy, Copernicus proposed a startling idea. He suggested that the Sun is at the center of the universe. Copernicus developed his model because it better explained the motions of the planets. Figure 25.2 shows both the Earth-centered and Sun-centered models. Copernicus did not publish his new model until his death. He knew that it was heresy to say that Earth was not the center of the universe. It wasnt until Galileo developed his telescope that people would take the Copernican Today we know that we have eight planets, five dwarf planets, over 165 moons, and many, many asteroids and other small objects in our solar system. We also know that the Sun is not the center of the universe. But it is the center of the solar system. Figure 25.3 shows our solar system. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Table 25.1 gives some data on the mass and diameter of the Sun and planets relative to Earth. Object Mass (Relative to Earth) Sun Mercury Venus Earth Mars Jupiter Saturn Uranus 333,000 Earths mass 0.06 Earths mass 0.82 Earths mass 1.00 Earths mass 0.11 Earths mass 317.8 Earths mass 95.2 Earths mass 14.6 Earths mass Diameter of Planet (Relative to Earth) 109.2 Earths diameter 0.39 Earths diameter 0.95 Earths diameter 1.00 Earths diameter 0.53 Earths diameter 11.21 Earths diameter 9.41 Earths diameter 3.98 Earths diameter Neptune 17.2 Earths mass Youve probably heard about Pluto. When it was discovered in 1930, Pluto was called the ninth planet. Astronomers later found out that Pluto was not like other planets. For one thing, what they were calling Pluto was not a single object. They were actually seeing Pluto and its moon, Charon. In older telescopes, they looked like one object. This one object looked big enough to be a planet. Alone, Pluto was not very big. Astronomers also discovered many objects like Pluto. They were rocky and icy and there were a whole lot of them. Astronomers were faced with a problem. They needed to call these other objects planets. Or they needed to decide that Pluto was something else. In 2006, these scientists decided what a planet is. According to the new definition, a planet must: Orbit a star. Be big enough that its own gravity causes it to be round. Be small enough that it isnt a star itself. Have cleared the area of its orbit of smaller objects. If the first three are true but not the fourth, then that object is a dwarf planet. We now call Pluto a dwarf planet. There are other dwarf planets in the solar system. They are Eris, Ceres, Makemake and Haumea. There are many other reasons why Pluto does not fit with the other planets in our solar system. Figure 25.4 shows the Sun and planets with the correct sizes. The distances between them are way too small. In general,

Context: Freshwater below Earths surface is called groundwater. The water infiltrates, or seeps down into, the ground from the surface. How does this happen? And where does the water go? Water infiltrates the ground because soil and rock are porous. Between the grains are pores, or tiny holes. Since water can move through this rock it is permeable. Eventually, the water reaches a layer of rock that is not porous and so is impermeable. Water stops moving downward when it reaches this layer of rock. Look at the diagram in Figure 13.11. It shows two layers of porous rock. The top layer is not saturated; it is not full of water. The next layer is saturated. The water in this layer has nowhere else to go. It cannot seep any deeper into the ground because the rock below it is impermeable. The top of the saturated rock layer in Figure 13.11 is called the water table. The water table isnt like a real table. It doesnt remain firmly in one place. Instead, it rises or falls, depending on how much water seeps down from the surface. The water table is higher when there is a lot of rain and lower when the weather is dry. An underground layer of rock that is saturated with groundwater is called an aquifer. A diagram of an aquifer is shown in Figure 13.12. Aquifers are generally found in porous rock, such as sandstone. Water infiltrates the aquifer from the surface. The water that enters the aquifer is called recharge. Most land areas have aquifers beneath them. Many aquifers are used by people for freshwater. The closer to the surface an aquifer is, the easier it is to get the water. However, an aquifer close to the surface is also more likely to become polluted. Pollutants can seep down through porous rock in recharge water. An aquifer that is used by people may not be recharged as quickly as its water is removed. The water table may lower and the aquifer may even run dry. If this happens, the ground above the aquifer may sink. This is likely to damage any homes or other structures built above the aquifer. One of the biggest aquifers in the world is the Ogallala aquifer. As you can see from Figure 13.13, this aquifer lies beneath parts of eight U.S. states. It covers a total area of 451,000 square kilometers (174,000 square miles). In some places, it is less than a meter deep. In other places, it is hundreds of meters deep. The Ogallala aquifer is an important source of freshwater in the American Midwest. This is a major farming area, and much of the water is used to irrigate crops. The water in this aquifer is being used up ten times faster than it is recharged. If this continues, what might happen to the Ogallala aquifer? The top of an aquifer may be high enough in some places to meet the surface of the ground. This often happens on a slope. The water flows out of the ground and creates a spring. A spring may be just a tiny trickle, or it may be a big gush of water. One of the largest springs in the world is Big Spring in Missouri, seen in Figure 13.14. Water flowing out of the ground at a spring may flow downhill and enter a stream. Thats what happens to the water that flows out of Big Spring in Missouri. If the water from a spring cant flow downhill, it may spread out to form a pond or lake instead. Lake George in New York State, which is pictured in Figure 13.15, is a spring-fed lake. The lake basin was carved by a glacier. Some springs have water that contains minerals. Groundwater dissolves minerals out of the rock as it seeps through the pores. The water in some springs is hot because it is heated by hot magma. Many hot springs are also mineral springs. Thats because hot water can dissolve more minerals than cold water. Grand Prismatic Spring, shown in Figure 13.16, is a hot mineral spring. Dissolved minerals give its water a bright blue color. The edge of the spring is

Context: The war had three phases. Initially it was a localized feud between supporters of Gebhard and those of the Catholic core of the Cathedral Chapter. With the election of Ernst of Bavaria as a competing archbishop, what had been a local conflict expanded in scale: Ernst's election guaranteed the military, diplomatic, and financial interest of the Wittelsbach family in the Electorate of Cologne's local affairs. After the deaths of Louis VI, Elector Palatine in 1583and William the Silent in 1584, the conflict shifted gears again, as the two evenly matched combatants sought outside assistance to break the stalemate. Finally, the intervention of Alexander Farnese, Duke of Parma, who had at his command the Spanish Army of Flanders, threw the balance of power in favor of the Catholic side. By 1588, Spanish forces had pushed Gebhard from the Electorate. In 1588 he took refuge in Strassburg, and the remaining Protestant strongholds of the Electorate fell to Parma's forces in 1589.

Context: Do you know what your blood type is? Maybe you have heard people say that they have type A or type O blood. Blood type is a way to describe the type of antigens, or proteins, on the surface of red blood cells (RBCs). There are four blood types; A, B, AB, and O. 1. Type A blood has type A antigens on the RBCs in the blood. 2. Type AB blood has A and B antigens on the RBCs. 3. Type B has B antigens on the RBCs. 4. Type O does not have either A or B antigens. The ABO blood group system is important if a person needs a blood transfusion. A blood transfusion is the process of putting blood or blood products from one person into the circulatory system of another person. The blood type of the recipient needs to be carefully matched to the blood type of the donor. Thats because different blood types have different types of antibodies, or proteins, released by the blood cells. Antibodies attack strange substances in the body. This is a normal part of your immune response, which is your defense against disease. For example, imagine a person with type O blood was given type A blood. First, what type of antibodies do people with type O blood produce? They produce anti-A and anti-B antibodies. This means, if a person with type O blood received type A blood, the anti-A antibodies in the persons blood would attack the A antigens on the RBCs in the donor blood ( Figure 1.1). The antibodies would cause the RBCs to clump together, and the clumps could block a blood vessel. This clumping of blood cells could cause death. A person with type O blood has A and B antibodies in his/her plasma; if the person was to get type A blood instead of type O, his/her A antibodies would attach to the antigens on the RBCs and cause them to clump together. People with type A blood produce anti-B antibodies, and people with type B blood produce anti-A antibodies. People with type AB blood do not produce either antibody. The second most important blood group system in human blood is the Rhesus (Rh) factor. A person either has, or does not have, the Rh antigen on the surface of their RBCs. If they do have it, then the person is positive. If the person does not have the antigen, they are considered negative. Recall that people with type O blood do not have any antigens on their RBCs. As a result, type O blood can be given to people with blood types A, B, or AB. If there are no antigens on the RBCs, there cannot be an antibody reaction in the blood. People with type O blood are often called universal donors. The blood plasma of AB blood does not contain any anti-A or anti-B antibodies. People with type AB blood can receive any ABO blood type. People with type AB blood are called universal recipients because they can receive any blood type. The antigens and antibodies that define blood type are listed as follows ( Table 1.1). Blood Type Antigen Type Plasma Antibodies A B AB O A B A and B none anti-B anti-A none anti-A, anti-B Can Receive Blood from Types A,O B,O AB, A, B, O O Can Donate Blood to Types A, AB B, AB AB AB, A, B, O

Context: Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials. A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress. Compression squeezes rocks together, causing rocks to fold or fracture (break) (Figure 1.1). Compression is the most common stress at convergent plate boundaries. Stress caused these rocks to fracture. Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries. When forces are parallel but moving in opposite directions, the stress is called shear (Figure 1.2). Shear stress is the most common stress at transform plate boundaries. Shearing in rocks. The white quartz vein has been elongated by shear. When stress causes a material to change shape, it has undergone strain or deformation. Deformed rocks are common in geologically active areas. A rocks response to stress depends on the rock type, the surrounding temperature, the pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress. Rocks have three possible responses to increasing stress (illustrated in Figure 1.3): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks. Under what conditions do you think a rock is more likely to fracture? Is it more likely to break deep within Earths crust or at the surface? What if the stress applied is sharp rather than gradual? At the Earths surface, rocks usually break quite quickly, but deeper in the crust, where temperatures and pressures are higher, rocks are more likely to deform plastically. Sudden stress, such as a hit with a hammer, is more likely to make a rock break. Stress applied over time often leads to plastic deformation. Click image to the left or use the URL below. URL:

Context: In Europe, before the outbreak of the war, the Allies had significant advantages in both population and economics. In 1938, the Western Allies had a 30 per cent larger population and a 30 per cent higher gross domestic product than the European Axis powers ; if colonies are included, it then gives the Allies more than a 5:1 advantage in population and nearly 2:1 advantage in GDP. In Asia at the same time, China had roughly six times the population of Japan, but only an 89 per cent higher GDP; this is reduced to three times the population and only a 38 per cent higher GDP if Japanese colonies are included. The United States provided about two-thirds of all the ordnance used by the Allies in terms of warships, transports, warplanes, artillery, tanks, trucks, and ammunition. Though the Allies' economic and population advantages were largely mitigated during the initial rapid blitzkrieg attacks of Germany and Japan, they became the decisive factor by 1942, after the United States and Soviet Union joined the Allies, as the war largely settled into one of attrition. While the Allies' ability to out-produce the Axis is often attributed to the Allies having more access to natural resources, other factors, such as Germany and Japan's reluctance to employ women in the labour force, Allied strategic bombing, and Germany's late shift to a war economy contributed significantly. Additionally, neither Germany nor Japan planned to fight a protracted war, and were not equipped to do so. To improve their production, Germany and Japan used millions of slave labourers; Germany used about 12 million people, mostly from Eastern Europe, while Japan used more than 18 million people in Far East Asia.

Context: The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air. Reducing air pollution from vehicles can be done in a number of ways. Breaking down pollutants before they are released into the atmosphere. Motor vehicles emit less pollution than they once did because of catalytic converters (Figure 1.1). Catalytic converters contain a catalyst that speeds up chemical reactions and breaks down nitrous oxides, carbon monoxide, and VOCs. Catalytic converters only work when they are hot, so a lot of exhaust escapes as the car is warming up. Catalytic converters are placed on mod- ern cars in the United States. Making a vehicle more fuel efficient. Lighter, more streamlined vehicles need less energy. Hybrid vehicles have an electric motor and a rechargeable battery. The energy that would be lost during braking is funneled into charging the battery, which then can power the car. The internal combustion engine only takes over when power in the battery has run out. Hybrids can reduce auto emissions by 90% or more, but many models do not maximize the possible fuel efficiency of the vehicle. A plug-in hybrid is plugged into an electricity source when it is not in use, perhaps in a garage, to make sure that the battery is charged. Plug-in hybrids run for a longer time on electricity and so are less polluting than regular hybrids. Plug-in hybrids began to become available in 2010. Developing new technologies that do not use fossil fuels. Fueling a car with something other than a liquid organic-based fuel is difficult. A fuel cell converts chemical energy into electrical energy. Hydrogen fuel cells harness the energy released when hydrogen and oxygen come together to create water (Figure 1.2). Fuel cells are extremely efficient and they produce no pollutants. But developing fuel-cell technology has had many problems and no one knows when or if they will become practical. Pollutants are removed from the exhaust streams of power plants and industrial plants before they enter the atmo- sphere. Particulates can be filtered out, and sulfur and nitric oxides can be broken down by catalysts. Removing these oxides reduces the pollutants that cause acid rain. Particles are relatively easy to remove from emissions by using motion or electricity to separate particles from the gases. Scrubbers remove particles and waste gases from exhaust using liquids or neutralizing materials (Figure 1.3). Gases, such as nitrogen oxides, can be broken down at very high temperatures. A hydrogen fuel-cell car looks like a gasoline-powered car. Scrubbers remove particles and waste gases from exhaust. Gasification is a developing technology. In gasification, coal (rarely is another organic material used) is heated to extremely high temperatures to create syngas, which is then filtered. The energy goes on to drive a generator. Syngas releases about 80% less pollution than regular coal plants, and greenhouse gases are also lower. Clean coal plants do not need scrubbers or other pollution control devices. Although the technology is ready, clean coal plants are more expensive to construct and operate. Also, heating the coal to high enough temperatures uses a great deal of energy, so the technology is not energy efficient. In addition, large amounts of the greenhouse gas CO2 are still released with clean coal technology. Nonetheless, a few of these plants are operating in the United States and around the world. How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are: Riding a bike or walking instead of driving

Context: Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teen who is playing tennis in Figure 16.1 is using force to move her tennis racket, so she is doing work. The teen who is studying isnt moving anything, so she is not doing work. Not all force that is used to move an object does work. For work to be done, the force must be applied in the same direction that the object moves. If a force is applied in a different direction than the object moves, no work is done. Figure 16.2 illustrates this point. The stick person applies an upward force on the box when raising it from the ground to chest height. Work is done because the force is applied in the same direction as the box is moving. However, as the stick person walks from left to right while holding the box at chest height, no more work is done by the persons arms holding the box up. Thats because the force supporting the box acts in a different direction than the box is moving. A small amount of work in the horizontal direction is performed when the person is accelerating during the first step of the walk across the room. But other than that, there is no work, because there is no net force acting on the box horizontally. Work is directly related to both the force applied to an object and the distance the object moves. It can be represented by the equation: Work = Force Distance This equation shows that the greater the force that is used to move an object or the farther the object is moved, the more work that is done. You can see a short video introduction to work as the product of force and distance at this link: . To see the effects of force and distance on work, compare the weight lifters in Figure 16.3. The two weight lifters on the left are lifting the same amount of weight, but the bottom weight lifter is lifting the weight a longer distance. Therefore, this weight lifter is doing more work. The two weight lifters on the bottom right are both lifting the weight the same distance, but the weight lifter on the left is lifting a heavier weight. Therefore, this weight lifter is doing more work. The equation for work given above can be used to calculate the amount of work that is done if force and distance are known. For example, assume that one of the weight lifters in Figure 16.2 lifts a weight of 400 newtons over his head to a height of 2.2 meters off the ground. The amount of work he does is: Work = 400 N 2.2 m = 880 N m Notice that the unit for work is the newton meter. This is the SI unit for work, also called the joule (J). One joule equals the amount of work that is done when 1 newton of force moves an object over a distance of 1 meter. Problem Solving Problem: Todd pushed a 500 N box 4 meters across the floor. How much work did he do? Solution: Use the equation Work = Force Distance. Work = 500 N 4 m = 2000 N m, or 2000 J You Try It! Problem: Lara lifted a 100 N box 1.5 meters above the floor. How much work did she do? Did you ever rake leaves, like the woman in Figure 16.4? It can take a long time to do all that work. But if you use an electric leaf blower, like the man in the figure, the job gets done much sooner. Both the leaf blower and the rake do the work of removing leaves from the yard, but the leaf blower has more power. Thats why it can do the same amount of work in less time. Power is a measure of the amount of work that can be done in a given amount of time. Power can be represented by the equation: Power = Work Time In this equation, work is measured in joules and time is measured in seconds, so power is expressed in joules per second (J/

Context: New Orleans narcotics detective Anthony Stowe (Jean-Claude Van Damme) is a heroin addict who is teetering on the edge of oblivion, and he couldn't care less.At the moment, Stowe is trying to bring down his former partner Gabriel Callahan (Stephen Rea), who has become a drug kingpin. Callahan is trying to, and slowly succeeding at, taking over the New Orleans underworld.Stowe botches a sting operation against Callahan, resulting in the death of fellow cop Maria Ronson (Rachel Grant), whose fiancee, fellow cop Van Huffel (Adam Leese), is furious at Stowe. Chief Mac Baylor (Gary Beadle) has a very blunt chat with Stowe about it. Stowe is approached by fellow cop Walter Curry (Trevor Cooper) to help his nephew beat a drug-dealing charge. Stowe instead turns him over to Baylor, who fires him. After barricading himself in the station bathroom, Walter confronts an unrepentant Stowe and condemns him for betraying his fellow officers.Later, Van Huffel berates Stowe for getting Maria killed. Stowe responds by attacking Van Huffel in front of several officers. Later, Stowe meets with his estranged wife Valerie (Selina Giles), who tells him that she's pregnant, but that he's not the father. Valerie, whose marriage with Stowe is on the rocks, has been seeing a man named Mark Rossini (Mark Dymond), the gym teacher at the school she is principle of. But he may not be the father either. Stowe brashly accuses Valerie of being impregnated by Callahan, and Valerie tells him she never wants to see him again.The only thing keeping Stowe from total collapse is his dogged pursuit of Callahan. But he drunkenly stumbles into an ambush masterminded by Callahan, and is shot in the head by Callahan's right-hand man Jimmy (Stephen Lord).Stowe undergoes emergency surgery, and ends up in a coma. Months later, he recovers to the point that he opens his eyes, and is transported to his and Valerie's house to recover properly.Seven months after getting shot, Stowe has recovered a lot, although he must learn to walk and speak again. He manages to survive an attempt on his life, by someone who appears to be a cop. He's recovered enough to try to get his job back, but that's the one thing that Chief Baylor doesn't want to give him. The coma has led to his decision to become a better man, and to right some wrongs. He reconciles with his wife, although awkwardly, and gives Walter a check for $40,000, part of his insurance money that compensated his time in a coma. Finally, he visits the grave of fellow police officer Serge (William Ash), who once saved Stowe's life but has been killed by an unknown attacker following another failed sting operation.Valerie packs up to move out of the house so she can live with Mark, but after realizing the change that Stowe has undergone, she later decides to leave Mark and come back home. Stowe is convinced by his friend Chad Mansen (Wes Robinson) not to let his wife go, and Stowe goes after her. They miss each other by a few minutes.Just after Valerie returns and meets Chad, some of Callahan's men show up. Jimmy kills Chad, and kidnaps Valerie. Stowe returns to the house, and finds Chad's body, along with Jimmy waiting for him.Van Damme promoting the film in 2007Jimmy takes Stowe to a warehouse where Callahan is waiting. Along the way, Stowe manages to overpower Jimmy and take his gun, but he finds that the odds against him are impossible- and Callahan has Valerie hostage. Van Huffel is revealed to be Callahan's mole on the police force, and the sting operation at the beginning of the film was a set-up. Walter suddenly arrives and saves Stowe. Together they kill all of Callahan's men, including Jimmy and Van Huffel, as Callahan tries to escape with Valerie to his helicopter. Just as Callahan is about to reach it, Stowe appears.In the European DVD ending, each fire a shot that kills the other. Valerie cries out

Context: Coming off their road win over the Steelers, the Colts went home for a Week 11 AFC South rematch with the Houston Texans. In the first quarter, Indianapolis trailed early as Texans kicker Kris Brown got a 28-yard field goal. The Colts responded with kicker Adam Vinatieri getting a 40-yard field goal. Houston would answer with Brown making a 34-yard field goal. In the second quarter, Indy tied the game as Vinatieri got a 39-yard field goal. The Texans retook the lead as RB Ahman Green got a 1-yard TD run. Indianapolis closed out the half as Vinatieri made a 32-yard field goal. In the third quarter, the Colts took the lead as QB Peyton Manning completed a 23-yard TD pass to RB Joseph Addai. Houston would reply as RB Steve Slaton got a 71-yard TD run, yet Indy regained the lead as Addai got a 7-yard TD run. In the fourth quarter, the Texans tried to come back as Green got a 2-yard field goal, yet Indianapolis pulled away with Vinatieri nailing a 31-yard field goal. On the Texans' final drive, QB Sage Rosenfels was intercepted by safety Melvin Bullitt (who was filling in again for the injured Bob Sanders). Ironically, it was Bullitt who picked off Rosenfels on the Texans' final drive when they played the Colts in Week 5. Manning then took a knee, preserving the Colts' third consecutive victory.

Context: You're in your office when you learn there's someone with a gun wandering outside. You can hear gunshots and screams. What do you do? That's the challenge for users of a new virtual reality program called SurviVR, designed to train employees how to deal with an active shooter situation in the workplace. The program works with HTC Vive, the virtual reality headset released earlier this year. An active shooter situation is when an armed person or people actively shoot in a small, populated area with the intention to kill. There were 20 such situations in the United States last year and 20 the year before, according to FBI statistics, resulting in a total of 231 deaths. This year saw the deadliest active shooter situation in US history , with 49 people killed in a nightclub in Orlando. In the training situation, users have four choices. They can lock themselves in the office. They can hide, perhaps in the office closet. They can run for an exit. Or they can use something in the office--a computer or a cup a pair of scissors-as a weapon to fight the shooter. This is an improvement on standard active shooter training. Gallo says, which typically teachers people to lock themselves in place and hide. The "lock down" method is often ineffective, he says, and has resulted in many deaths in recent years. In the training's basic level, no one gets killed. But as the trainings become more advanced, players who make a wrong choice be shot. There's no blood; the screen simply turns black slowly. If this sounds terrifying, that's the point, says Gallo. There are plenty of training programs to teach employees how to deal with workplace violence, sometimes involving role play with toy guns. But these trainings are basically games. Gallo says, with employees relaxed and even enjoying themselves. To teach people what they really need to know for an active shooter situation, they need to be scared. "SurviVR will take the fear and turn it into confidence." Gallo says.

Context: All rocks on Earth change, but these changes usually happen very slowly. Some changes happen below Earths surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form and how they change. Figure 4.1 shows how the three main rock types are related to each other. The arrows within the circle show how one type of rock may change to rock of another type. For example, igneous rock may break down into small pieces of sediment and become sedimentary rock. Igneous rock may be buried within the Earth and become metamorphic rock. Igneous rock may also change back to molten material and re-cool into a new igneous rock. Rocks are made of minerals. The minerals may be so tiny that you can only see them with a microscope. The minerals may be really large. A rock may be made of only one type of mineral. More often rocks are made of a mixture of different minerals. Rocks are named for the combinations of minerals they are made of and the ways those minerals came together. Remember that different minerals form under different environmental conditions. So the minerals in a rock contain clues about the conditions in which the rock formed (Figure 4.2). Geologists group rocks based on how they were formed. The three main kinds of rocks are: 1. Igneous rocks form when magma cools below Earths surface or lava cools at the surface (Figure 4.3). 2. Sedimentary rocks form when sediments are compacted and cemented together (Figure 4.4). These sediments may be gravel, sand, silt or clay. Sedimentary rocks often have pieces of other rocks in them. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. 3. Metamorphic rocks form when an existing rock is changed by heat or pressure. The minerals in the rock change but do not melt (Figure 4.5). The rock experiences these changes within the Earth. Rocks can be changed from one type to another, and the rock cycle describes how this happens. Any type of rock can change and become a new type of rock. Magma can cool and crystallize. Existing rocks can be weathered and eroded to form sediments. Rock can change by heat or pressure deep in Earths crust. There are three main processes that can change rock: Cooling and forming crystals. Deep within the Earth, temperatures can get hot enough to melt rock. This molten material is called magma. As it cools, crystals grow, forming an igneous rock. The crystals will grow larger if the magma cools slowly, as it does if it remains deep within the Earth. If the magma cools quickly, the crystals will be very small. Weathering and erosion. Water, wind, ice, and even plants and animals all act to wear down rocks. Over time they can break larger rocks into smaller pieces called sediments. Moving water, wind, and glaciers then carry these pieces from one place to another. The sediments are eventually dropped, or deposited, somewhere. The sediments may then be compacted and cemented together. This forms a sedimentary rock. This whole process can take hundreds or thousands of years. Metamorphism. This long word means to change form. A rock undergoes metamorphism if it is exposed to extreme heat and pressure within the crust. With metamorphism, the rock does not melt all the way. The rock changes due to heat and pressure. A metamorphic rock may have a new mineral composition and/or texture. An interactive rock cycle diagram can be found here: The rock cycle really has no beginning or end. It just continues. The processes involved in the rock cycle take place over hundreds, thousands, or even millions of years. Even though for us rocks are solid and unchanging, they slowly change all the time.

Context: Somatic mutations in the tyrosine kinase (TK) domain of the epidermal growth factor receptor (EGFR) gene are reportedly associated with sensitivity of lung cancers to gefitinib (Iressa), kinase inhibitor. In-frame deletions occur in exon 19, whereas point mutations occur frequently in codon 858 (exon 21). We found from sequencing the EGFR TK domain that 7 of 10 gefitinib-sensitive tumors had similar types of alterations; no mutations were found in eight gefitinib-refractory tumors (P = 0.004). Five of seven tumors sensitive to erlotinib (Tarceva), a related kinase inhibitor for which the clinically relevant target is undocumented, had analogous somatic mutations, as opposed to none of 10 erlotinib-refractory tumors (P = 0.003). Because most mutation-positive tumors were adenocarcinomas from patients who smoked <100 cigarettes in a lifetime ("never smokers"), we screened EGFR exons 2-28 in 15 adenocarcinomas resected from untreated never smokers. Seven tumors had TK domain mutations, in contrast to 4 of 81 non-small cell lung cancers resected from untreated former or current smokers (P = 0.0001). Immunoblotting of lysates from cells transiently transfected with various EGFR constructs demonstrated that, compared to wild-type protein, an exon 19 deletion mutant induced diminished levels of phosphotyrosine, whereas the phosphorylation at tyrosine 1092 of an exon 21 point mutant was inhibited at 10-fold lower concentrations of drug. Collectively, these data show that adenocarcinomas from never smokers comprise a distinct subset of lung cancers, frequently containing mutations within the TK domain of EGFR that are associated with gefitinib and erlotinib sensitivity.

Context: This article needs an improved plot summary. (November 2015) Sidhu (Akshay Kumar) is a lowly vegetable cutter at a roadside food stall in the Chandni Chowk section of Delhi, who consults astrologers, tarot card readers, and fake fakirs despite his foster father Dada's (Mithun Chakraborty) exhortations. When two strangers from China claim him as a reincarnation of war hero 'Liu Shen' and take him to China, Sidhu, encouraged by trickster Chopstick (Ranvir Shorey), believes he will be feted as a hero, unaware of his own recruitment to assassinate the smuggler Hojo (Gordon Liu). Sidhu travels to China with Chopstick. Along the way he meets Sakhi (Deepika Padukone), the Indian-Chinese spokesmodel known as Ms. Tele Shoppers Media, or Ms. TSM, who also appears in China. Her twin sister Suzy, known as the femme fatale Meow Meow, works for Hojo, not knowing Hojo tried to kill her father, Inspector Chiang (Roger Yuan). Sidhu, through a series of accidents, initially eludes Hojo, but Hojo eventually exposes him as a fraud. Thereupon Hojo kills Dada, and Sidhu is beaten and urinated on by Hojo. Injured and disgraced Sidhu vows revenge. He thereafter encounters an amnesiac vagrant, whom he later identifies to Sakhi as Inspector Chiang. Chiang later recovers his memory and trains Sidhu in kung fu. When Hojo again meets with Sidhu, Suzy injures Chiang; but upon seeing Sakhi, betrays Hojo. Sidhu fights Hojo in single combat, eventually using a modified vegetable-cutting technique to overwhelm him. In the aftermath, Sidhu opens a vegetable stall in China, but is recruited to fight for some African pygmies. The film thereupon concludes with the announcement "To be Continued Chandni Chowk to Africa".

Context: Carbon is an element. By itself, its a black solid. You can see a lump of carbon in Figure 18.10. Carbon is incredibly important because of what it makes when it combines with many other elements. Carbon can form a wide variety of substances. For example, in the air, carbon combines with oxygen to form the gas carbon dioxide. In living things, carbon combines with several other elements. For example, it may combine with nitrogen and In the carbon cycle, carbon moves through living and nonliving things. Carbon actually moves through two cycles that overlap. One cycle is mainly biotic; the other cycle is mainly abiotic. Both cycles are shown in Figure 18.11. Producers such as plants or algae use carbon dioxide in the air to make food. The organisms combine carbon dioxide with water to make sugar. They store the sugar as starch. Both sugar and starch are carbohydrates. Consumers get carbon when they eat producers or other consumers. Carbon doesnt stop there. Living things get energy from food in a process called respiration. This releases carbon dioxide back into the atmosphere. The cycle then repeats. Carbon from decaying organisms enters the ground. Some carbon is stored in the soil. Some carbon may be stored underground for millions of years. This will form fossil fuels. When volcanoes erupt, carbon from the mantle is released as carbon dioxide into the air. Producers take in the carbon dioxide to make food. Then the cycle repeats. The oceans also play an important role in the carbon cycle. Ocean water absorbs carbon dioxide from the air. In fact, the oceans contain 50 times more carbon than the atmosphere. Much of the carbon sinks to the bottom of the oceans, where it may stay for hundreds of years. Human actions are influencing the carbon cycle. Burning of fossil fuels releases the carbon dioxide that was stored in ancient plants. Carbon dioxide is a greenhouse gas and is a cause of global warming. Forests are also being destroyed. Trees may be cut down for their wood, or they may be burned to clear the land for farming. Burning wood releases more carbon dioxide into the atmosphere. You can see how a tropical rainforest was cleared for farming in Figure 18.12. With forests shrinking, there are fewer trees to remove carbon dioxide from the air. This makes the greenhouse effect even worse. Living things also need nitrogen. Nitrogen is a key element in proteins. Like carbon, nitrogen cycles through ecosystems. You can see the nitrogen cycle in Figure 18.13. Air is about 78 percent nitrogen. Decomposers release nitrogen into the air from dead organisms and their wastes. However, producers such as plants cant use these forms of nitrogen. Nitrogen must combine with other elements before producers can use it. This is done by certain bacteria in the soil. Its called fixing nitrogen. Nitrogen is one of the most important nutrients needed by plants. Thats why most plant fertilizers contain nitrogen. Adding fertilizer to soil allows more plants to grow. As a result, a given amount of land can produce more food. So far, so good. But what happens next? Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. The nitrogen is a fertilizer in the water bodies. Since there is a lot of nitrogen it causes algae to grow out of control. Figure 18.14 shows a pond covered with algae. Algae may use up so much oxygen in the water that nothing else can grow. Soon, even the algae die out. Decomposers break down the dead tissue and use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico. You can see it Figure 18.14.
