Macromolecules are formed by combining single units, called monomers, together to form a chain, called polymers.
Answer: Option B
Step-by-step explanation:
Polymers are substances that are formed when many molecules of monomers are linked together to form a complete chain, this may be a homopolymer when identical monomers are linked together or a heteropolymer in which non identical monomers are linked together.
Many of our biomolecules are polymers that arise by continuous linkage of monomers for example protein which contains amino acids as its monomers.
