Question

a student claims that the sugars produced by plants during photosynthesis provide a carbon skeleton that interacts with other elements to form biomolecules like amino acids, lipids, nucleic acids. which statement should the student give in support of the claim? all biomolecules contain carbon, hydrogen, and oxygen. all biomolecules break down to release energy in the form of atp. all biomolecules are made up of repeating monosaccharides. all biomolecules have nearly the same molecular structures and shapes.

Explanation:

Biomolecules are carbon - based. Sugars from photosynthesis provide carbon skeletons. All biomolecules contain carbon, hydrogen, and oxygen, which supports the idea that the carbon from sugars can be used to form other biomolecules like nucleic acids. The other statements are either incorrect (not all biomolecules break down to release energy as ATP, not all are made of repeating monosaccharides, and they don't have nearly the same molecular structures) or not relevant to the carbon - skeleton claim.

Answer:

All biomolecules contain carbon, hydrogen, and oxygen.
