उत्तर
Melanin is a pigment found both in the skin and in hair. It is significant for two reasons: first, it gives our skin color, and the tone of our skin is determined by the amount of melanin pigment, and second, it protects our skin and internal organs from ultraviolet rays. If the melanin pigment is gone, all humans will have the same skin color, making us vulnerable to the UV radiation in our environment.
