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.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
