3.sulfur

4.hydrogen

Answer 1

Answer:

2, 4

Explanation:

Carbohydrates only contain the elements CHO (carbon, hydrogen, oxygen), so those are the only ones that could be used in the other types of molecules.  Also, those molecules also contain the CHO molecules, so we can confirm that carbon and hydrogen will be used by the body for the production of proteins and lipids.
