Answer the following question given this paragraph: Digestion includes both mechanical and chemical processes. Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with. Q: Which form of digestion is a purely physical process that does not change the chemical nature of the food? Choices: - slow - simple - electromagnetic - mechanical A:
mechanical

Q: Answer the following question given this paragraph: The direction of prevailing winds determines which type of air mass usually moves over an area. For example, a west wind might bring warm moist air from over an ocean. An east wind might bring cold dry air from over a mountain range. Which wind prevails has a big effect on the climate. What if the prevailing winds are westerlies? The westerlies blow from nearer the Equator to farther from the Equator. How would they affect the climate?. Q: The direction of prevailing winds determines the type of what that usually moves over an area? Choices: - storm - water mass - weather - air mass A:
A: air mass
Question: Answer the following question given this paragraph: Upwelling also takes place along the Equator. Winds blow the surface water north and south. This leaves a void that deep water can upwell into. The nutrients rise to the surface and support a great deal of life in the equatorial oceans. Q: Deep water filling a void caused by surface winds blowing water north and south is known as? Choices: - downwelling - surface current - divergence - upwelling A:
Answer: upwelling

Answer the following question given this paragraph: Leaves are the keys not only to plant life but to all terrestrial life. The primary role of leaves is to collect sunlight and make food by photosynthesis. Despite the fundamental importance of the work they do, there is great diversity in the leaves of plants. However, given the diversity of habitats in which plants live, it's not surprising that there is no single best way to collect solar energy for photosynthesis. Q: What is the part of a plant whose primary role is to collect sunlight and make food by photosynthesis? Choices: - roots - stems - seeds - leaves A:
**Answer**
leaves
Answer the following question given this paragraph: Electronegativity is a qualitative measure of how much an atom attracts electrons in a covalent bond. Q: Electronegativity is a qualitative measure of how much an atom attracts what in a covalent bond? Choices: - neutrons - protons - isotopes - electrons A:
electrons
