Question

Quizplus · Accepted Answer

Melanin is a pigment that provides protection from ultraviolet radiation by absorbing and dissipating the energy from the radiation, which prevents it from damaging the skin cells. Carotene is a pigment that gives yellow and orange color to fruits and vegetables but does not provide protection from UV radiation. Hemoglobin is a protein found in blood and does not have a role in protecting from UV radiation. Vitamin D helps in the absorption of calcium and phosphate from diet but does not protect from UV radiation. Melanocytes are the cells that produce melanin and are involved in protecting from UV radiation, but the answer choice specifically asks for what protects, and the protection comes from the pigment melanin, not the melanocytes.
