<em><u>A. Neither the subjects nor the researchers can bias the results.</u></em>
Explanation:
As described, a double- blind study is one in which the researcher and his study does not know the person receiving the actual treatment.
Researchers can be bias in their studies as they seek to establish and fine tune results in the way the best favors them. A double-blind study helps to bridge this gap to prevent bias that might be introduced into an experimental set up or while interpreting results.

It's purpose is to break down energy from carbohydrates and other organic molecules stored during photosynthesis
The answer here is ATP.
ATP is used in the first step of glycolysis to convert glucose into glucose-6-phosphate (that's where the phosphate comes from).
