Question

which of the following is the correct matching of monomer and macromolecule?*carbohydrate and lipid.dna and protein.monosaccharide and carbohydrate.

Explanation:

Monosaccharides are the simplest form of carbohydrates and serve as the building blocks (monomers) for larger carbohydrate molecules (polysaccharides, which are macromolecules).
DNA is a nucleic acid (macromolecule) made up of nucleotides (monomers), not proteins. Proteins are macromolecules made from amino acid monomers.
Lipids are a diverse group of macromolecules (not built from a single type of monomer in the same linear fashion as some other macromolecules like proteins or nucleic acids). Carbohydrates (like polysaccharides) are macromolecules made from monosaccharide monomers.

Answer:

monosaccharide and carbohydrate.
