Answer the following question given this paragraph: Refer again to water's phase diagram ( Figure above ). Notice point E, labeled the critical point . What does that mean? At 373.99C, particles of water in the gas phase are moving very, very rapidly. At any temperature higher than that, the gas phase cannot be made to liquefy, no matter how much pressure is applied to the gas. The critical pressure (P c ) is the pressure that must be applied to the gas at the critical temperature in order to turn it into a liquid. For water, the critical pressure is very high, 217.75 atm. The critical point is the intersection point of the critical temperature and the critical pressure. Q: What is the intersection point of the critical temperature and the critical pressure called? Choices: - instance point - basic juncture - peak point - critical point A:
critical point
Q: Answer the following question given this paragraph: The girl pictured above became negatively charged because electrons flowed from the van de Graaff generator to her. Whenever electrons are transferred between objects, neutral matter becomes charged. This occurs even with individual atoms. Atoms are neutral in electric charge because they have the same number of negative electrons as positive protons. However, if atoms lose or gain electrons, they become charged particles called ions. You can see how this happens in the Figure below . When an atom loses electrons, it becomes a positively charged ion, or cation. When an atom gains electrons, it becomes a negative charged ion, or anion. Q: Gain or loss of what causes an atom to become a negatively or positively charged ion? Choices: - protons - neutrons - nucleus - electrons A:
A: electrons
Question: Answer the following question given this paragraph: For a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. If a hypothesis cannot be tested by making observations, it is not scientific. Consider this statement:. Q: A hypothesis is scientific only if it can be tested by what? Choices: - independent variable - making a conclusion - carbon dating - making observations A:
Answer: making observations

Answer the following question given this paragraph: Q: What does the moving piston in an engine turn? Choices: - hammer - muffler - brake - crankshaft A:
**Answer**
crankshaft
Q: Answer the following question given this paragraph: Intermediate filaments have no role in cell movement. Their function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place. Figure 4.22 shows how intermediate filaments create a supportive scaffolding inside the cell. The intermediate filaments are the most diverse group of cytoskeletal elements. Several types of fibrous proteins are found in the intermediate filaments. You are probably most familiar with keratin, the fibrous protein that strengthens your hair, nails, and the epidermis of the skin. Q: What is the most familiar fibrous protein found in your body? Choices: - cellulose - Actin - Collagen - keratin A:
A: keratin
