What is the primary protective function of the pigment melanin in the skin?

To insulate the body from cold temperatures.

To absorb high-energy ultraviolet radiation.

To facilitate the production of skin oils.

To increase the skin's elasticity and strength.

How does melanin prevent UV energy from harming deeper tissues?

It cools the skin surface, neutralizing the energy.

It captures the UV energy at the skin's surface.

It reflects all incoming sunlight like a mirror.

It repairs damaged DNA in cells immediately.

Their skin is physically thicker and tougher.

Their skin can absorb more UV energy at the surface.

Their skin cells are genetically programmed to repair any sun-induced damage more quickly and efficiently.

Their skin reflects a significantly higher percentage of all incoming solar radiation, including visible and infrared light.

It absorbs energy only during the daytime and reflects it at night.

It is present in only certain types of specialized skin cells.

It has a tuned ability to specifically absorb high-energy UV wavelengths.

It allows beneficial nutrients to enter the skin while blocking harmful toxins.

Deeper tissue damage from UV radiation.

A chronic inability to regulate body temperature.

An inability for the skin to stretch and flex, leading to premature wrinkling and cracking.

A severe overproduction of vitamin D, which can lead to toxicity in the body's systems.
