L_0322 | surface ocean currents | DD_0095 | The diagram below shows the types of Ocean current. An ocean current is a continuous, directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the Coriolis effect, cabbeling, temperature and salinity differences, while tides are caused by the gravitational pull of the Sun and Moon. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents flow for great distances, and together, create the global conveyor belt which plays a dominant role in determining the climate of many of the EarthÕs regions. More specifically, ocean currents influence the temperature of the regions through which they travel. For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them. Perhaps the most striking example is the Gulf Stream, which makes northwest Europe much more temperate than any other region at the same latitude. Another example is Lima, Peru where the climate is cooler (sub-tropical) than the tropical latitudes in which the area is located, due to the effect of the Humboldt Current. | image | teaching_images/ocean_currents_7109.png |
L_0322 | surface ocean currents | DD_0096 | This diagram shows the way ocean and waves move. Most ocean waves are caused by winds. A wave is the transfer of energy through matter. A wave that travels across miles of ocean is traveling energy, not water. Ocean waves transfer energy from wind through water. The energy of a wave may travel for thousands of miles. The water itself moves very little. Ocean water also moves from the deep sea to the ocean surface. Places where this happens are called areas of upwelling. The marine life and the climate can be affected as the cold water makes its way up from the deep. | image | teaching_images/ocean_currents_7107.png |

L_0403 | first two lines of defense | DD_0160 | The diagram shows the process of phagocytosis in a phagocyte cell. Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. Phagocytosis is the process of taking in particles such as bacteria, parasites, dead host cells, and cellular and foreign debris by a cell. From the diagram, attachment first occurs after the bacteria is bound to molecules called "receptors" that are on the surface of the phagocyte. Ingestion then takes place as the phagocyte then stretches itself around the bacterium and engulfs it. Once inside the phagocyte, the bacterium is trapped in a compartment called a phagosome. Within one minute the phagosome merges with a lysosome with digestive enzymes to form a phagolysosome. The bacterium is then subjected to an overwhelming array of killing mechanisms and is digested and discharged from the cell. | image | teaching_images/phagocytosis_9210.png |
L_0403 | first two lines of defense | DD_0161 | This diagram shows the process called Phagocytosis. Through this process, our defense system fights bacteria and destroys them keeping them out of our system. An amoeba is a type of cell or organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. Once the white blood cells detect any inflammation, they go to where damaged tissue is located and eat pathogens and dead cells by engulfing and destroying them. In order to do this, bacteria is digested and nutrients are absorbed and the waste products are expulsed out by the amoeba. | image | teaching_images/phagocytosis_9211.png |

L_0404 | immune system defenses | DD_0162 | The diagram shows the main parts of the lymphatic system. The lymphatic system is part of the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph directionally towards the heart. The lymphatic system also functions as a defense mechanism in the immune system. A lymph node is an oval- or kidney-shaped organ of the lymphatic system, present widely throughout the body including the armpit (axillary) , pelvic, lumbar and stomach and linked by lymphatic vessels. Lymph nodes are major sites of B, T, and other immune cells called Lymphocytes. Lymphocytes are concentrated in the lymph nodes. The spleen and the thymus are also lymphoid organs of the immune system. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and cancer cells. | image | teaching_images/human_system_immune_9117.png |
L_0404 | immune system defenses | DD_0163 | This diagram shows the some of the organs in the human body that are involved in the immune system. The organs shown here include bone marrow, the thymus gland, the spleen, and the tonsils and the adenoids. Each organ has a different job in the immune system. Bone marrow is found inside many bones. Its role in the immune system is to produce white blood cells. The thymus gland is in the chest behind the breast bone. It stores some types of white blood cells while they mature. The spleen is in the abdomen below the thymus gland. Its job is to filter pathogens out of the blood. The two tonsils are located on either side of the throat and is located above the thymus gland. They trap pathogens that enter the body through the mouth or nose.The lymph nodes are present in the head just below the jaw. They are also located under the armpits and in the groin area. Lymph nodes act like filters and remove pathogens from lymph. Lymph vessels make up a circulatory system that is similar to the blood vessels of the cardiovascular system. However, lymph vessels circulate lymph instead of blood. | image | teaching_images/human_system_immune_9110.png |

L_0422 | cell structures | DD_0178 | This diagram shows the Anatomy of an Animal cell. Animal cells are have outer boundary known as the plasma membrane. The nucleus and the organelles of the cell are bound by a membrane. The genetic material (DNA) in animal cells is within the nucleus that is bound by a double membrane. The cell organelles have a vast range of functions to perform like hormone and enzyme production to providing energy for the cells. They are of various sizes and have irregular shapes. Most of the cells size range between 1 and 100 micrometers and are visible only with help of microscope. The animal cells perform variety of activities by the aid of the cellular organelles. These cells function as a unit and the cells together form tissues. A group go tissues with similar function form an organ and a group of organ of specific function to perform becomes and organ system. | image | teaching_images/parts_cell_1182.png |
L_0422 | cell structures | DD_0179 | This diagram is of a plant cell. A plant cell has a cell wall and chloroplast, which sets it apart from an animal cell. The cell wall and membrane work to protect the cell. The chloroplast reflects green light, which gives plants their green color. Its ribosomes produce proteins. Its vacuole stores material. Its mitochondria provides energy and is known as the powerhouse of the cell. The nucleus and nucleolus store genetic material and work to control the cell and reproduce. The endoplasmic reticulum and Golgi apparatus play a role in producing proteins and moving materials, respectively. A given plant will have millions of these tiny cells that each work in different areas to provide life. | image | teaching_images/parts_cell_3181.png |
L_0422 | cell structures | DD_0180 | This diagram shows the cross section of an animal cell. It shows several parts of the cell such as the cell membrane, nucleus, mitochondrion, ribosomes and golgi body. The outermost part of the cell is called the cell membrane. It resembles a bag holding the cytoplasm and other parts of the cell. Cytoplasm is everything inside the cell membrane including the gell like cytosol. The nucleus is the largest organelle in the animal cell. It has an outer covering called the nuclear membrane. The nucleus contains most the cells DNA. The ribosomes are small organelles where proteins are made. The endoplasmic reticulum labelled as Rough ER and Smooth ER are organelles that help transport proteins and lipids. It is made up of folded membranes. | image | teaching_images/parts_cell_1166.png |
L_0422 | cell structures | DD_0181 | The image below shows the Prokaryotic cell. A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organelle. In the prokaryotes, all the intracellular water-soluble components (proteins, DNA and metabolites) are located together in the cytoplasm enclosed by the cell membrane, rather than in separate cellular compartments. Bacteria, however, do possess protein-based bacterial microcompartments, which are thought to act as primitive organelles enclosed in protein shells. At least some prokaryotes also contain intracellular structures that can be seen as primitive organelles. Membranous organelles (or intracellular membranes) are known in some groups of prokaryotes, such as vacuoles or membrane systems devoted to special metabolic properties, such as photosynthesis or chemolithotrophy. In addition, some species also contain carbohydrate-enclosed microcompartments, which have distinct physiological roles (e.g. carboxysomes or gas vacuoles). | image | teaching_images/parts_cell_6232.png |
L_0422 | cell structures | DD_0182 | This image shows the cross section of a plant cell. These eukaryotic cells differ in several key aspects from the cells of other eukaryotic organisms. Several structures are shown, such as the Golgi body, the chloroplast, the nucleus and the nucleolus. The Golgi body is a large organelle that sends proteins and lipids where they are necessary. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains most of the cellÕs DNA. The cell wall is a thick, rigid membrane made of cellulose that surrounds a plant cell. The vacuole is a large sac-like structure within a plant cell that is filled with fluid. The mitochondrion converts the energy stored in glucose into ATP, that is, adenosine triphosphate, for the cell. | image | teaching_images/parts_cell_1177.png |
