20 points how can monomers make larger molecules

The monomers combine with each other via covalent bonds to form larger molecules known as polymers.

Explanation:

A monomer is a type of molecule that has the ability to chemically bond with other molecules in a long chain; a polymer is a chain of an unspecified number of monomers. Essentially, monomers are the building blocks of polymers, which are more complex type of molecules

and example of such is seen in several monosaccharides (glucose, fructose)joining together to form polysaccharide like starch

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the answer is b.) hydrogen bonds between bases.
