The skin possesses a number of amazing protective properties, and one of the most notable is skin coloration as a protection against U. V. irradiation. Briefly, describe the anatomical, biochemical and physical means by which the skin adapts to U. V. radiation. How does light (U. V.) potentially disrupt cellular function and how is melanin poised to protect against damage. Describe four features of melanin as it relates to interpersonal differences between individuals, and what impact does this have on rates of skin cancer. Describe at least one method used to associate U. V. irradiation with either skin damage or repair.

Melanin is a skin pigment.

Explanation:

Melanin is a skin pigment that is present in the bottom layer of the skin's epidermis. Melanin may help protect the skin from Ultraviolet rays. Increasing in the concentration of melanin may block processes in the body that lead to skin cancer. Ultraviolet light kills cells by damaging their DNA. The light starts a reaction between two molecules of thymine which is one of the bases that is responsible for the formation of DNA molecule. Melanin has the ability to absorb Ultraviolet light which automatically protects skin cells. The presence of melanin in the skin decreases the rate of skin cancer diseases around the world.

explanation:

eventually, the disease can cause permanent damage or deterioration of the nerves. some people with ms experience a gradual onset and steady risk factors.
