Question 1

Question

You work for a company that manufactures food products. A new "wonder food" contains only carbon, oxygen, and hydrogen. At this point, your research can say with certainty that the food ______.

a
could only be made of carbohydrates
b
includes proteins
c
could only be made of triglycerides
d
does not include proteins or nucleic acids

Answer 1

The correct answer is:

d does not include proteins or nucleic acids

Explanation: Proteins and nucleic acids contain nitrogen in addition to carbon, hydrogen, and oxygen. Since the "wonder food" contains only carbon, oxygen, and hydrogen, it cannot contain proteins or nucleic acids. While it could be carbohydrates or lipids (like triglycerides), we cannot conclude definitively that it could only be made of triglycerides or carbohydrates without more information.
