Question

number correct 10 number incorrect 2 many building blocks are joined together to make a large biological macromolecule. this chain of sub - units is called a(n)... a. isomer b. monomer c. dimer d. polymer

Explanation:

To solve this, we analyze each option:

• Option A: Isomers are compounds with the same formula but different structures, not related to building blocks forming a chain. Eliminate A.
• Option B: Monomers are the individual building blocks, not the chain of sub - units. Eliminate B.
• Option C: Dimers are formed from two monomers, not a long chain of sub - units. Eliminate C.
• Option D: Polymers are large molecules (macromolecules) made by joining many monomer sub - units in a chain. This matches the description in the question.

Answer:

D. Polymer
