1. X chromosome inactivation

Explanation:

X chromosome inactivation is a process that shuts down one X chromosome in all the cells of a female during early embryonic stages. It is done to balance the dosage of X-linked genes in males and females. The process of X chromosome inactivation is random which means that either paternal or maternal X chromosome may be inactivated in the cells. The inactivated X chromosome in a cell is transmitted to all of its daughter cells.

Therefore, some cells of a female express the paternal X chromosome while others express the maternal X chromosome. The random expression of the paternal or maternal X chromosome in females results in patches of cells with or without sweat glands.

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
