Nitella [24]
The statement in the given question that presents a condition of the Hardy-Weinberg principle is that random mating occurs. The correct option among all the options given in the question is option "C". There are definitely certain conditions under which the Hardy- Weinberg principle occurs and they are when there is no gene flow, no mutations happen, no generic drift occurs and random mating occurs. This principle also states a very important aspect and it is that genotype and allele frequencies will always remain constant from one generation to another if there is absence of other evolutionary inflrnce.

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.
