Answer 1

Answer;

Amino acids

Proteins are important biomolecules that build organisms and direct chemical reactions. Proteins are polymers composed of long chains of Amino acids.

Explanation;

Proteins are macromolecules that are composed of amino acids, and a single protein molecule may contain as many as 5,000 amino acid molecules. The amino acids that make up the protein molecule constitute its primary structure

Amino acids are the basic building blocks of proteins; contains a carboxyl group (-COOH) and an amino group (-NH2).

Answer 2

Proteins are polymers composed of long chains of amino acids. Amino acids are the monomers of proteins, therefore, long chains of them would create a polymer. Hope this helps! :)
