Which of the following is not a function of skin?

a- provide support for the body

b- protect the body

c- from vitamin d

d- rid the body of waste

D- rid the body of waste

Explanation:

The skin covers our entire body protecting against external aggressions. It is a great “cover” against fungi, bacteria, chemicals, physics and even environmental factors such as the sun. This protective barrier comes from the epidermis and dermis cells, sebum secretion and sweat, forming a special cover, like a protective cloak. In addition to protection, the skin supports the body and the main intake of vitamin D in the body. However, it is not the skin's function to rid the body of waste.

some people are more predisposed to developing cancer when exposed to mutagens

Explanation:

Cancer predisposition is a term that means that an individual is more likely to develop cancer during his or her life due to genetic and other factors. Usually these individuals have relatives who have had some form of cancer and know that there is a greater possibility that they have too. This is not to say that cancer-prone individuals will have cancer someday, only that the chances of getting the disease are higher.

People predisposed to cancer are more likely to develop cancer when exposed to mutagens and this is a likely reason to explain why some tobacco users develop cancer and others do not.
