Answer:
A) Dehydration reactions assemble polymers, and hydrolysis reactions break down polymers
Explanation:
because the Dehydration reactions have a rule in forming polymers from monomer, when the dehydration synthesis reactions assemble the huge biological molecules and start to form more monomers connect each other by a covalent bond until form a chain of monomers then start to lose a water molecule , and start to synthesis and form a new bond
and it's the same way when the polymers break down into monomers by hydrolysis reactions when a water molecule will be added , because it will form a new bond
