Polymers described as large molecules built up from small repeating units called________________?
Correct answer: C. Monomers
- A. Biopolymers
- B. Dimers
- C. Monomers
- D. metamers
Explanation
Polymers are very large molecules made by repeatedly joining small molecules called monomers, so monomer is the correct term for the repeating building material. A dimer contains only two joined units, while biopolymer and metamer describe neither the general building unit nor this definition.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
