hypothalamus
Q: Answer the following question given this paragraph: The global pattern of precipitation is influenced by movements of air masses. For example, there is a global belt of dry air masses and low precipitation at about 30 N and 30 S latitude. Q: The global pattern of precipitation is influenced by movements of what? Choices: - pollution masses - air valleys - clouds - air masses A:
A: air masses
Question: Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. They contain a material such as silicon that absorbs light energy and gives off electrons. The electrons flow and create electric current. Figure below and the animation at the URL below show how a solar cell uses light energy to produce electric current and power a light bulb. Many calculators and other devices are also powered by solar cells. Q: What do solar cells convert the energy in sunlight into? Choices: - free energy - experimental energy - subsequent energy - electrical energy A:
Answer: electrical energy

Answer the following question given this paragraph: Vacuoles are membrane-bound organelles that can have secretory, excretory, and storage functions. Vacuoles are usually much larger than vesicles. Many organisms will use vacuoles as storage areas and some plant cells have very large vacuoles. The large central vacuole of the plant cell is used for osmotic control (storage of water) and nutrient storage. Contractile vacuoles are found in certain protists. These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to osmotic pressure. Q: These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to what? Choices: - apoptotic pressure - static pressure - impervious pressure - osmotic pressure A:
**Answer**
osmotic pressure
(Q).
Answer the following question given this paragraph: You can see several examples of people or things in motion in Figure below . You can probably think of many other examples. You know from experience what motion is, so it may seem like a straightforward concept. Motion can also be defined simply, as a change in position. But if you think about examples of motion in more depth, you'll find that the idea of motion is not quite as simple and straightforward as it seems. Q: What can be defined simply, as a change in position? Choices: - velocity - gravity - speed - motion A:
(A).
motion
