Why does prolonged exposure to uv light from the sun or tanning beds increase the risk for getting skin cancer? a. increased exposure to uv light decreases the risk of a mutation occurring b. increased exposure to uv light increases the risk of a mutation occurring c. increased exposure to uv light decreases the immune system function d. increased exposure to uv light has no effect on the risk for getting skin cancer

Option B, increased exposure to UV light increases the risk of a mutation occurring

Explanation:

Ultraviolet radiations (UV) coming from the sun are radioactive waves that affect the skin. They not only cause skin infection, irritation, but are are also potential source of cancer causing agent . Some times these radiations on prolonged exposure  causes genetic mutations in the skin cells which continues though ages.

Ultraviolet rays are short wavelength radiations and the shorter is the wavelength of any radiation, the greater is the potential harm caused by it.

Hence, UV rays are harmful.

Option B is correct
