Answer the following question given this paragraph: The energy of motion is kinetic energy, KE. Whenever an object is in motion it has kinetic energy. The faster it is going, the more energy it has. Q: What is the term for the energy of motion, which is exhibited by the speed of an object? Choices: - inertia - mechanical energy - residual energy - kinetic energy A:
kinetic energy

Answer the following question given this paragraph: The folded surfaces of the gills provide a large surface area to ensure that the fish gets sufficient oxygen. Diffusion is a process in which material travels from regions of high concentration to low concentration until equilibrium is reached. In this case, blood with a low concentration of oxygen molecules circulates through the gills. The concentration of oxygen molecules in water is higher than the concentration of oxygen molecules in gills. As a result, oxygen molecules diffuse from water (high concentration) to blood (low concentration), as shown in Figure 39.5. Similarly, carbon dioxide molecules in the blood diffuse from the blood (high concentration) to water (low concentration). Q: What term is used to describe a process in which material travels from regions of high concentration to low concentration until equilibrium is reached? Choices: - fission - active transport - Osmosis - diffusion A:
(Answer)
diffusion
Ques: Answer the following question given this paragraph: A catalyst is a substance that increases the speed of a reaction. Overall, a catalyst is not a reactant and is not used up, but it still affects how fast a reaction proceeds. However, a catalyst does not affect the extent or position of a reaction at equilibrium. It helps a reaction achieve equilibrium faster. Q: What is the term for a substance that causes the speed of a reaction to increase? Choices: - indicate - component - monite - catalyst A:
Ans: catalyst

(A).
slime molds and water molds
Ques:Answer the following question given this paragraph: Coal is the source of most electricity. Q: What is the source of most electricity? Choices: - methane - the Sun - air - coal A:

Ans:coal
Ques:Answer the following question given this paragraph: The electrochemical potential across a membrane determines the tendency of an ion to cross the membrane. The membrane may be that of a cell or organelle or other sub cellular compartment. The electrochemical potential arises from three factors:. Q: The electrochemical potential across a membrane determines the tendency of an ion to do what? Choices: - attach to the membrane - move away from the membrane - destroy the membrane - cross the membrane A:

Ans:
cross the membrane
