Answer the following question given this paragraph: There is not just one distinguishing feature that separates a living thing from a non-living thing. A cat moves but so does a car. A tree grows bigger, but so does a cloud. A cell has structure, but so does a crystal. Biologists define life by listing characteristics that living things share. Something that has all of the characteristics of life is considered to be alive. The duck decoy in Figure below may look like a duck, act like a duck in that it floats about, but it is not alive. The decoy cannot reproduce, respond to its environment, or breathe. Q: Something that has all of the characteristics of life is considered to be what? Choices: - molecule - organism - ecosystem - alive A:
alive

Q: Answer the following question given this paragraph: Plate movements cause continents to drift closer to the poles or the Equator. Ocean currents also shift when continents drift. All these changes can affect Earth's temperature. Q: What causes continents to drift closer to the poles or the equator? Choices: - wind - sediment movements - tidal pull - plate movements A:
A: plate movements

Answer the following question given this paragraph: The way in which a reaction is written influences the value of the enthalpy change for the reaction. Many reactions are reversible, meaning that the product(s) of the reaction are capable of combining and reforming the reactant(s). If a reaction is written in the reverse direction, the sign of the changes. For example, we can write an equation for the reaction of calcium oxide with carbon dioxide to form calcium carbonate. Q: The reaction of calcium oxide with carbon dioxide forms what? Choices: - nitrogen carbonate - carbon monoxide - nitrogen - calcium carbonate A:
(Answer)
calcium carbonate
