Answer:
Most macromolecules are also atoms binding together. Polymers are made up of numerous monomers.
(Correct option atoms - monomers)
Explanation:
Atoms are the structural unit of matter, with chemical properties that allow their interaction with other atoms to create molecules. An example of this is common salt, a molecule that is formed by the union of sodium and chlorine.
A monomer is a molecule, such as glucose (C₆H₁₂O₆), which when joined to other monomers of the same type can form a polymer. An example of this is cellulose, a biological polymer formed by multiple β-glucose units.
