What role does melanin play in the body?

• A. It acts as a hormone regulating sleep
• B. It is a pigment responsible for color in skin, scales, and feathers
• C. It helps in the digestion of food
• D. It provides energy to cells

Answer: (B)

Melanin serves as a pigment responsible for giving color to the skin, scales, and feathers in various animals, including humans. This pigment is produced by specialized cells called melanocytes and plays a significant role in determining the color of an individual's skin and hair. In humans, increased melanin production can provide some protection against ultraviolet (UV) radiation from the sun, which can lead to skin damage. Additionally, melanin contributes to the coloration found in animals, influencing camouflage, attraction, and signaling within various species. This fundamental role in pigmentation is crucial for both aesthetic and protective functions in living organisms.
