Answer: a chemical reaction

input with options: Answer the following question given this paragraph: Plants that live in extremely dry environments have the opposite problem: how to get and keep water. Plants that are adapted to very dry environments are called xerophytes . Their adaptations may help them increase water intake, decrease water loss, or store water when it is available. Q: Plants that live in the desert are called? A:
OPTIONS:
- xerozoans
- heatophiles
- sporozoans
- xerophytes
output: xerophytes

Q: Answer the following question given this paragraph: In deductive reasoning, I make a specific prediction based on a general principle. One general principle is that acids turn blue litmus paper red. If I have a bottle of liquid labeled "acid," I expect the litmus paper to turn red when I immerse it in the liquid. Q: Making a specific prediction based on a general principle is known as what type of reasoning? A:

OPTIONS:
- common sense reasoning
- logical reasoning
- validating reasoning
- deductive reasoning

A: deductive reasoning

input: OPTIONS:
- oxygen
- fuel
- food
- waste product Now, answer this question: Answer the following question given this paragraph: Gas Exchange across the Alveoli In the body, oxygen is used by cells of the body's tissues and carbon dioxide is produced as a waste product. The ratio of carbon dioxide production to oxygen consumption is the respiratory quotient (RQ). RQ varies between 0.7 and 1.0. If just glucose were used to fuel the body, the RQ would equal one. One mole of carbon dioxide would be produced for every mole of oxygen consumed. Glucose, however, is not the only fuel for the body. Protein and fat are also used as fuels for the body. Because of this, less carbon dioxide is produced than oxygen is consumed and the RQ is, on average, about 0.7 for fat and about 0.8 for protein. The RQ is used to calculate the partial pressure of oxygen in the alveolar spaces within the lung, the alveolar PO Above, 2 the partial pressure of oxygen in the lungs was calculated to be 150 mm Hg. However, lungs never fully deflate with an exhalation; therefore, the inspired air mixes with this residual air and lowers the partial pressure of oxygen within the alveoli. This means that there is a lower concentration of oxygen in the lungs than is found in the air outside the body. Knowing the RQ, the partial pressure of oxygen in the alveoli can be calculated:. Q: In the body, oxygen is used by cells of the body's tissues and carbon dioxide is produced as what? A:
A:
output: waste product
