Answer the following question given this paragraph: Plant-like protists are commonly called algae (alga, singular) . Some algae consist of single cells. They are called diatoms. Other algae are multicellular. An example is seaweed. Seaweed called kelp can grow as large as trees. You can see both a diatom and kelp in Figure below . Algae are probably ancestors of plants. Q: Plant-like protists are commonly called what? Choices: - fungus - sponge - seaweed - algae A:
algae

Choices: - air - gravity - carbon - light A:
light

Answer the following question given this paragraph: A puddle of water left undisturbed eventually disappears. The liquid molecules escape into the gas phase, becoming water vapor. Vaporization is the process in which a liquid is converted to a gas. Evaporation is the conversion of a liquid to its vapor below the boiling temperature of the liquid. If the water is instead kept in a closed container, the water vapor molecules do not have a chance to escape into the surroundings and so the water level does not change. As some water molecules become vapor, an equal number of water vapor molecules condense back into the liquid state. Condensation is the change of state from a gas to a liquid. Q: What is the change of state from a gas to a liquid? Choices: - vaporation - combustion - fermentation - condensation A:
**Answer**
condensation

Answer the following question given this paragraph: Some resources can't be renewed. At least, they can't be renewed fast enough to keep up with use. Fossil fuels are an example. It takes millions of years for them to form. We are using them up much more quickly. Elements that are used to produce nuclear power are also non-renewable resources. Uranium, for example, which is rare. Sooner or later, it will run out. Q: Uranium is an example of a non-renewable resource used to produce what type of power? Choices: - water - wind - electrical - nuclear A:
**Answer**
