b) 23 chromosomes
c) 46 pairs of chromosomes
d) 2 pairs of sex chromosomes
e) 1 pair of autosomes

Answer 1

Human cells have 23 pairs of chromosomes, comprising 22 pairs of autosomes and one pair of sex chromosomes, totaling 46 chromosomes.

Step-by-step explanation:

Human cells typically contain 23 pairs of chromosomes, totaling 46 chromosomes. Of these pairs, 22 are autosomes, which are the chromosome pairs numbered from 1 to 22 and are the same in both males and females. The 23rd pair consists of the sex chromosomes, which determine the sex of the individual: females have two X chromosomes while males have one X and one Y chromosome.
