Many macromolecules are made of component pieces, attached together into long chains. which of the following correctly pairs one of the four macromolecules with its component piece? a) rna; protein b) lipid; amino acid c) protein; nucleic acid d) complex carbohydrate; simple sugar

D complex carbohydrate; simple sugar

Explanation:

The 4 macromolecules are Proteins, lipids, nucleic acids and carbohydrates.

The component piece for each are as follows:

Protein = amino acid

Nucleic acid = nucleotides

Lipids = fatty acids, glycerol

Complex carbohydrates (polysaccharides) = simple sugars such as glucose
