Polymers are made of individual subunit called monomer.
<u>Explanation:</u>
Polymers are lengthy chains built up of replicating molecular subunits, named monomers. The term polymer becomes from poly- (many) and -mer (part). A polymer may be a real or manufactured macromolecule composed of recurring units of a smaller molecule (monomers). The term monomer comes from mono- (one) and -mer (part).
Monomers make polymers by creating chemical bonds or confining supramolecular by a method called polymerization. Examples of polymers comprise plastics like polyethylene, silicones. Polymerization is the method of covalently bonding the smaller monomers into the polymer. While polymerization, chemical groups are failed from the monomers so that they may join together.

Explanation:
Answer:
1. the middle piece contains the chromosomes. FALSE
2. the tail contains the mitochondria. FALSE
3. the acrosome is next to the tail. FALSE
4. the head contains 46 chromosomes. FALSE
5. the acrosome is next to the nucleus, and the head contains 23 chromosomes. TRUE
Explanation:
The major parts of a mature spermatozoan in human males are the head, middle piece and the tail. The head of the sperm is a flattened and pointed structure that contains a nucleus. There are 23 chromosomes present in the nucleus. Chromosome surrounds the anterior two-thirds of the nucleus. The acrosome is a caplike vesicle and is filled with hydrolytic enzymes that help a sperm during fertilization. The middle piece contains mitochondria that provide the energy (ATP) for locomotion of sperm to the site of fertilization and for sperm metabolism.
