Q: I can use this background: Hydrogen bonds cause water to have a relatively high boiling point of 100°C (212°F). Because of its high boiling point, most water on Earth is in a liquid state rather than in a gaseous state. Water in its liquid state is needed by all living things. Hydrogen bonds also cause water to expand when it freezes. This, in turn, causes ice to have a lower density (mass/volume) than liquid water. The lower density of ice means that it floats on water. For example, in cold climates, ice floats on top of the water in lakes. This allows lake animals such as fish to survive the winter by staying in the water under the ice.  Now, I have a new situation: Scientists are finding more and more evidences of water in the outer space. Earth has mostly liquid water. But that's not the case with other celestial objects. Venus has some water, but it is in gaseous state. On the other hand, water in Jupiter's moon Europa is in frozen state.  Answer this question please: Would Earth be less or more conducive for life than Venus?
A: more

Q: I can use this background: As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell’s needs. This idea is explained in Figure below . However, large cells have a way of dealing with some size challenges. Big cells, such as some white blood cells, often grow more nuclei so that they can supply enough proteins and RNA for the cell’s requirements. Large, metabolically active cells often have lots of cell protrusions, resulting in many folds throughout the membrane. These folds increase the surface area available for transport of materials into or out of the cell. Such cell types are found lining your small intestine, where they absorb nutrients from your food through protrusions called microvilli .  Now, I have a new situation: There are two cells inside a Petri dish in a laboratory, cell X and cell Z. These cells are from the same organism, but have different characteristics. For example, cell Z is smaller than cell X. Furthermore, scientists studying the two cells have recorded that cell X is more metabolically active than cell Z.  Answer this question please: Will cell Z have a larger or smaller surface area to transport materials?
A: smaller

Q: I can use this background: This is how ice wedging works. When liquid water changes into solid ice, it increases in volume. You see this when you fill an ice cube tray with water and put it in the freezer. The ice cubes go to a higher level in the tray than the water. You also may have seen this if you put a can of soda into the freezer so that it cools down quickly. If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can. (For the record, water is very unusual. Most substances get smaller when they change from a liquid to a solid.)  Now, I have a new situation: Jeremy is performing some chores around the kitchen when he decides to pour himself some water into a blue cup. However, this water isn't cold enough so he puts it into the freezer to cool it down. He then pours himself the exact same amount of water in a red cup, but gets a phone call and leaves that cup on the table without taking a sip. He comes back two hours later after the phone call to get his cups of water back.  Answer this question please: Will the water in the red or blue cup have more volume?
A: blue

Q: I can use this background: East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded.  Now, I have a new situation: Two teams of scientists were in Antarctica to study the weather. Camp Alpha was located in East Antarctica, while camp Omega was situated in West Antarctica.  Answer this question please: Which camp experienced more snowfall?
A:
