The correct answer is C. 46.
A human cell contains 46 chromosomes, which are found in the nucleus. Chromosomes are made up of DNA, which is the genetic material that contains the instructions for how the body grows and functions.
The 46 chromosomes are divided into 23 pairs. 22 of these pairs are called autosomes, and the remaining pair is called the sex chromosomes. Females have two X chromosomes, while males have one X chromosome and one Y chromosome.
The number of chromosomes in a cell can vary depending on the type of cell. For example, sperm cells and egg cells only have 23 chromosomes each. This is because when a sperm cell fertilizes an egg cell, the resulting cell (a zygote) has 46 chromosomes.
The number of chromosomes in a cell can also change due to a genetic disorder. For example, people with Down syndrome have an extra copy of chromosome 21.
Chromosomes are important because they contain
