Polymers are large molecules made up of repeating structural units (monomers) connected by covalent bonds. Based on the options you've provided, the following molecules are considered polymers:
b. RNA (ribonucleic acid) - a polymer of nucleotides. f. cellulose - a polymer of glucose units. g. DNA (deoxyribonucleic acid) - a polymer of nucleotides. h. polypeptide - a polymer of amino acids.
The other options are not polymers: a. monosaccharide - a simple sugar and not a polymer. c. amino acid - a building block for proteins, but not a polymer on its own. d. ATP (adenosine triphosphate) - a nucleotide, but not a polymer. e. lipid - a class of biomolecules that typically includes fats and oils, but they are not true polymers.
So, the polymers from your list are: b, f, g, and h.
