Verified step by step guidance

Understand the definition of a polypeptide: A polypeptide is a chain of amino acids linked together by peptide bonds, which are formed through dehydration synthesis reactions.

Review the process of dehydration synthesis: This is a chemical reaction where water is removed to form a new bond, specifically between the carboxyl group of one amino acid and the amino group of another, resulting in a peptide bond.

Analyze the given options: Each option describes a different type of molecular interaction or structure, but none accurately describe a polypeptide.

Option 1 describes organic molecules linked by dehydration reactions, which is partially correct but too vague as it doesn't specify amino acids or peptide bonds.

Option 2 mentions organic monomers covalently bonded, which is a general description that could apply to many types of polymers, not specifically polypeptides.
