Question

Which of the following is not an example of a polymer?

Plastic

Nylon

Amino acid

Polystyrene

Answer 1

A polymer is made up of many repeating units called monomers.

For example a stack of connected lego blocks can be analogous to a polymer, as it is made up of many repeating units (lego blocks).

In this example the entire stack of connected lego blocks is the polymer, and the individual blocks that make up the stack are the monomers.

Which one of these is not made up of repeating units?

Answer 2

amino acid is a molecule and others are the polymers
protein is a polymer

Answer 3

amino acid is a molecule and others are the polymers
protein is a polymer made up of amino acid monomer
