multiple choice question
how many pairs of chromosomes are located in the nucleus of a typical human body cell?
○ 18
○ 23
○ 20
○ 46
○ 2

Explanation:

In human biology, a typical human body cell (somatic cell) has 23 pairs of chromosomes in its nucleus. This is a well - known fact in the field of biology (a subfield of Natural Science). The total number of chromosomes is 46, but when considering pairs, it is 23. The other options (18, 20, 2, 46) do not correctly represent the number of chromosome pairs in a typical human body cell.

Answer:

B. 23
