Whats are the functions of the integumentary system ?
Verdich [7]

Answer:

Absorption

Thousands of pores on the surface of the skin can absorb vitamins, acids, water and oxygen in order to provide moisture and nourishment to our skin.

Excretion

The skin is the body’s largest waste removal system. Toxins are released through the sweat glands and pores.

Secretion

The skin secretes sebum, a mixture of oils that keeps the skin soft and supple. The layer of sebum on the outermost layer of the skin is known as the acid mantle. When intact the acid mantle has a PH that ranges from 4.5-5.5. The acid mantle is acidic in nature to protect the skin from outside invasion.

Regulation

The skin regulates the body’s temperature by sweating; when water from sweat on the skin evaporates it gives off heat and cools the body.  The body’s temperature increases or by shivering or getting goosebumps when the body is cold. The contraction of muscles releases energy that warms the body.

Sensation

The skin contains millions of nerve endings that transport stimuli. These nerve endings allow humans to detect sensation such as heat, cold, pain and pressure.

Answer:

In their experiments, Hershey and Chase showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not. Hershey and Chase and subsequent discoveries all served to prove that DNA is the hereditary material.
