Answer the following question given this paragraph: In the liquid state, the hydrogen bonds of water can break and reform as the molecules flow from one place to another. When water is cooled, the molecules begin to slow down. Eventually, when water is frozen to ice, the hydrogen bonds become permanent and form a very specific network (see Figure below ). Q: As the temperature of water decreases what happens to the speed of the water molecules? Choices: - move faster - evaporate - begin to boil - slow down A:
slow down

Answer the following question given this paragraph: Aquatic biomes are water-based biomes. They include both freshwater biomes, such as rivers and lakes, and marine biomes, which are salt-water biomes in the ocean. The primary producers in most aquatic biomes are phytoplankton. Phytoplankton consist of microscopic bacteria and tiny algae that make food by photosynthesis. Unlike terrestrial biomes, which are determined mainly by temperature and moisture, aquatic biomes are determined mainly by sunlight and dissolved substances in the water. These factors, in turn, depend mainly on depth of water and distance from shore. Q: Salt-water biomes in the ocean are called what? Choices: - marine organelles - marine species - ocean biomes - marine biomes A:
(Answer)
marine biomes
Ques: Answer the following question given this paragraph: Green light has a higher frequency than microwaves. It is possible to calculate it, but since the speed of an electromagnetic wave is constant we know that waves with higher wavelengths must have a lower frequency based on the wave equation. Q: What of a electromagnetic wave can be calculated using the wave equation due to their speed always being constant? Choices: - oscillation - resonance - sound - frequency A:
Ans: frequency
(Q).
Answer the following question given this paragraph: The winds of a tornado can reach very high speeds. The faster the winds blow, the greater the damage they cause. Wind speed and damage are used to classify tornadoes. Table below shows how. Q: What is used to classify tornadoes? Choices: - seismograph - damage, snowfall - humidity, rain - wind speed, damage A:
(A).
wind speed, damage
Ques:Answer the following question given this paragraph: Lakes, ponds, streams, springs, and wetlands are fresh water bodies. The organisms that live in them are part of freshwater ecosystems. These ecosystems vary by temperature, pressure (in lakes), and the amount of light that penetrates. The type of plants that grow in these ecosystems varies. Q: Lakes, ponds, streams, springs, and wetlands are? Choices: - salt water bodies - man-made structures - land formations - fresh water bodies A:

Ans:fresh water bodies
Answer the following question given this paragraph: Efforts to reduce future global warming mainly involve energy use. We need to use less energy, for example, by driving more fuel-efficient cars. We also need to switch to energy sources that produce less carbon dioxide, such as solar and wind energy. At the same time, we can increase the amount of carbon dioxide that is removed from air. We can stop destroying forests and plant new ones. Q: Reducing the production of what gas, or removing it from the air, are practices that could reduce global warming? Choices: - helium - hydrogen - oxygen - carbon dioxide A:
carbon dioxide
