Melanin is a pigment that affects your skin to keep it the color it is. Melanin is brown. The more melanin in the skin, the darker the colour of the skin is. Melanin helps the skin by protecting it from the UV rays of the sun. Albinos are prone to a variety of skin diseases.Melanin are the cells in our skin that are colored. They are the color pigmentation that we have. The larger and closer together the cells are, the darker the skin color. When your talking about Hw, you are most likely talking about physics.
it protect us from sun. it helps us to not get a sun in our face so it can not get burned
There is a lot of sun where black people originate. The black coloring is caused by a pigment called melanin which helps protect skin from intense sun.
Yes they can. People with darker skin can stay in the sun for longer because they have a higher amount of Melanin. Melanin protects us from the harmful UV rays of the sun. :)
African People have darker skin because they have a higher amount of Melanin. Staying in the sun for long periods of time produces more Melanin. Melanin protects us from UV rays.
No, the Earth's gravitational field does not protect us from the sun. The gravitational pull between the Earth and sun keeps Earth in orbit, but it does not provide any physical protection from the sun's radiation or heat. The Earth's atmosphere and magnetic field help shield us from harmful solar radiation.
The Sun! Freckles are a way our skin tells us: "Hey, I'm getting damaged by the sun!" What is happening is that the pigment producing cells in the skin, called melanocytes feed melanin to the keratinocytes, the normal skin cells that form the outer barrier of our skin to protect us. It keeps the good stuff in and the bad stuff out. When the melanocytes in the skin get damaged by the sun, we produce freckles which are abnormal collections of melanin pigment, packaged in a different way than a normal melanin pigment is packaged. They sit on the top layer of our skin which is called the epidermis. http://www.freckles.org/whatcausesfreckles.html
Melanin The amount of melanin you have in your skin is determined by your genes- it is a genetic trait you were born with inherited from your mom and dad. The sun makes skin get darker. In addition- The sun's UV rays are absorbed by melanin in varying concentrations resulting in different skin colors/freckles/tans etc.... The lighter a person's natural skin color, the less melanin the skin has to absorb UV and protect itself. The darker a person's natural skin color, the more melanin the skin has to protect itself.
Your kidding with this right?
False
It protects us. It blocks the UV rays of the sun.
Do we have a skeleton to protect our organs and to help us move and support our body
