The type of bond that forms to join monomers (such as sugars and amino acids) into polymers (such as starch and proteins) is a(n) __________ bond.

• A. hydrogen
• B. ionic
• C. peptide
• D. van der Waals
• E. covalent

Answer: (E)

Verified step by step guidance

1. Understand that monomers are small molecules that can join together to form larger molecules called polymers.
2. Recognize that the process of joining monomers involves the formation of chemical bonds between them.
3. Identify the types of bonds listed: hydrogen, ionic, peptide, van der Waals, and covalent.
4. Recall that covalent bonds involve the sharing of electron pairs between atoms, which is a common way to link monomers into polymers.
5. Conclude that the type of bond that forms to join monomers into polymers, such as sugars into starch or amino acids into proteins, is a covalent bond.
