Which describes the relationship between a monomer and a polymer? a monomer is a type of polymer made of only one element. a collection of monomers combines to form a polymer. a substitution reaction changes a monomer into a polymer. a monomer is a type of polymer that forms from carbon chains.

A collection of monomers combines to form a polymer.

Explanation:-

Polymer is a macromolecule formed by the combination of simpler units called as monomers.

Polymers are of two types:-

Addition polymers : A polymer in which small units called as monomers are simply joined to form a bigger molecule called as addition polymer.  Example:

Condensation polymers : A polymer in which small units called as monomers are joined along with release of small by products to form a bigger molecule called as condensation polymer.
