Answer the following question given this paragraph: First, plant cells have a large central vacuole that holds a mixture of water, nutrients, and wastes. A plant cell's vacuole can make up 90% of the cell's volume. The large central vacuole essentially stores water. In animal cells, vacuoles are much smaller. Q: What does the large central vacuole do? Choices: - use water - create glucose - heat water - store water A:
(Answer)
store water
Ques: Answer the following question given this paragraph: The ideal gas law can also be used to determine the densities of gases. Density, recall, is defined as the mass of a substance divided by its volume:. Q: What is idefined as the mass of a substance divided by its volume? Choices: - weight - height - length - density A:
Ans: density
(Q).
Answer the following question given this paragraph: Local winds are winds that blow over a limited area. They are influenced by local geography. Nearness to an ocean, lake or mountain range can affect local winds. Some examples are found below. Q: What type of winds blow only over a limited area? Choices: - trade - Planetary - periodic - local A:
(A).
local
Ques:Answer the following question given this paragraph: There are three components that make up an electrochemical reaction. There must be a solution where redox reactions can occur. These reactions generally take place in water to facilitate electron and ion movement. A conductor must exist for electrons to be transferred. This conductor is usually some kind of wire so that electrons can move from one site to another. Ions also must be able to move through some form of salt bridge that facilitates ion migration. Q: What allows the electrons to move in an electrochemical system. Choices: - conduction - mass - magnetism - conductor A:

Ans:conductor
Answer the following question given this paragraph: Temperature falls from the equator to the poles. Therefore, major temperature zones are based on latitude. They include tropical, temperate, and arctic zones (see Figure below ). However, other factors besides latitude may also influence temperature. For example, land near the ocean may have cooler summers and warmer winters than land farther inland. This is because water gains and loses heat more slowly than does land, and the water temperature influences the temperature on the coast. Temperature also falls from lower to higher altitudes. That's why tropical zone mountain tops may be capped with snow. Q: Water gains and loses what more slowly than does land, affecting seasonal conditions inland and on the coast? Choices: - volume - humidity - minerals - heat A:
heat
