Answer the following question given this paragraph: When we consider a chemical reaction, we need to take into account both the system and the surroundings. The system includes the components involved in the chemical reaction itself. These will often take place in a flask, a beaker, a test tube, or some other container. The surroundings include everything that is not part of the system. When potassium reacts with water, part of the heat energy generated in the reaction is released into the surroundings. The boundary between system and surroundings is arbitrary, and it is generally chosen in a way that makes observations and calculations easier. Q: When we consider a chemical reaction, we need to take into account both the system and what? Choices: - date - fluctuations - time - sorroundings A:
sorroundings
Answer the following question given this paragraph: A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration. Q: What type of respiration has the advantage of releasing more energy? Choices: - kinetic - anaerobic - elastic - aerobic A:
aerobic
Q: Answer the following question given this paragraph: Droughts also depend on what is normal for a region. A region that gets significantly less precipitation than normal for an extended period of time is in drought. The Southern United States is experiencing an ongoing and prolonged drought. Q: What term is used to describe a region getting significantly less precipitation than normal for an extended period of time? Choices: - dog days - doldrums - flood - drought A:
A: drought
Question: Answer the following question given this paragraph: The zygote undergoes many cell divisions before it implants in the lining of the uterus. Q: The zygote undergoes many cell divisions before it implants in the lining of what? Choices: - vagina - ovaries - pelvis - uterus A:
Answer: uterus

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:
**Answer**
carbon dioxide
