Final answer:
Melanin determines skin color and is produced by melanocytes. Carotene and hemoglobin contribute to skin color; skin has various functions.
Explanation:
Melanin, a pigment in the epidermis, determines the color of human skin. It is produced by melanocytes and comes in two forms, eumelanin and pheomelanin, which affect hair and skin color.
Carotene and hemoglobin also contribute to skin color, especially in light-skinned individuals. Skin color variation is primarily regulated by the amount of melanin in the skin, with other factors playing a role as well.
The functions of the skin include protection from ultraviolet radiation, regulation of body temperature, and sensation of touch, illustrating its importance beyond just determining skin color.
