Question

monomers join together to form: atoms polymers enzymes lipids

Explanation:

Monomers are small molecules. When multiple monomers bond together through polymerization reactions, they form polymers. For example, glucose (a monomer) can join to form starch (a polymer). Atoms are the basic units of matter and are not formed by monomers. Enzymes are proteins (a type of polymer in some cases, but monomers don't directly form enzymes as a general category). Lipids are a different class of biomolecules, not formed by simple monomer - to - polymer linkage like many other macromolecules (e.g., proteins from amino acid monomers, nucleic acids from nucleotide monomers).

Answer:

Polymers
