Biological polymers are made by bringing together subunits, in a chemical reaction that generates a water molecule as a byproduct. This type of chemical reaction is called
a) aquagenesis
b) dehydration synthesis
c) the Wasserman effect
d) hydrodynamic synthesis

b) dehydration synthesis

Explanation:

Biological polymers are made up monomers, Which are combined together by covalent bond in dehydration synthesis. Such as polysaccharides are made up of monosaccahrides.Dehydration synthesis mean 'release a water molecule to come together'.The hydrogen of one monomer combine with hydroxyl group of another monomer to release water molecule.

Example; Glycosidic bond
