Compared to the amount of genetic information

contained in a normal human body cell, the

amount contained in a normal human sperm cell is

A. the same

B. twice as much

c. one-half as much

D. one-fourth as much

c. One half as much.

Explanation:

The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much the information contained in a normal human body cell (46 chromosomes). Sperm cells are produced during meiosis, a specialized division process that reduces the number of chromosomes in half, generating haploid daughter cells.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
