Question

What happens to monomers when they undergo dehydration synthesis?

Answer 1

They form long chain- like molecules.

Answer 2

Answer:

When monomers undergo dehydration to form large molecules. The monomers can be defined as the single molecules that combine to form a large molecules.

When large molecules are formed, monomers release water as a byproduct  during the synthesis of the polymer.

This reaction is known as the dehydration synthesis by which large biological molecules inside the body is formed.
