Final answer:
Somatic cells include all types of human body cells except for the sex cells (gametes). Somatic cells are diploid with 46 chromosomes, while gametes are haploid with 23 chromosomes. The correct answer is B. Correct sex cells.
Step-by-step explanation:
The somatic cells in the human body include a variety of cell types that contribute to the structure and function of tissues and organs. These cells are diploid, meaning they contain double the number of chromosomes found in reproductive cells, or gametes. Specifically, somatic cells have 46 chromosomes, including a pair of sex chromosomes, which is 23 pairs of homologous chromosomes. In contrast, gametes (sex cells) such as sperm and eggs only have 23 chromosomes; hence, they are haploid and do not have homologous pairs. Therefore, the correct answer to the question “Somatic cells include all of the following EXCEPT:” is B. Correct sex cells, as sex cells are the only type of cells in the human body that are not classified as somatic cells.
