Question

how are macromolecules made?
options:
biology
polymerization
monomerization
nanomerization

image shows a polymer and monomers with an arrow indicating the process.

Explanation:

The diagram shows monomers (small units) forming a polymer (large molecule), which is the process of polymerization. Biology is a broad field, monomerization and nanomerization are not standard terms for this process. Polymerization is the correct term for how macromolecules (polymers) are made from monomers.

Answer:

polymerization
