Explain the relationships between dehydration synthesis, hydrolysis, monomer, and polymer

combine with each other using covalent bonds

Explanation:

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

Dehydration synthesis is a process by which two monomers are linked to form a polymer, with water being given off as a byproduct.  Conversely, hydrolysis is the process by which water is introduced in order to break down a polymer into its monomer building blocks.
