What is melanin and what does it determine?
Melanin shields the nucleus from damage by ultraviolet radiation. It keeps this radiation from damaging the skin and DNA. It also gives color to your skin, hair, and irises. Melanin is a pigment which gives characteristic color to skin. Its main role is to absorb harmful UV radiations and protect our skin cells from damage. It determines the color of your skin. Melanin colors hair, skin, eyes, feathers, etc.
Ultraviolet rays are potentially harmful to us due to their?
Ultraviolet rays are potentially harmful to us due to their intensity. This is what is known as the amplitude of the rays from the sun.
Are tanning beds harmful or can ultraviolet light be beneficial?
yes they can be very harmful there known to cause skin cancer
What gives your skin its color?
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.
Can scorpions see in ultraviolet light?
No. They can not see in ultraviolet light. They are known to glow when exposed to ultraviolet light, though.
Is a ultraviolet is part of an human eye?
Ultraviolet, commonly known as UV rays, is a part of the electromagnetic radiations with wavelength in the range 400nm-10nm. It is not a part of the human eye. It is intact considered to be harmful the human eye, skin, etc. More information can be found on the link below.
How does melonin protect the body?
Melanocytes are found in the epidermis, mixed amongst the rest of your skin cells, known as keratinocytes. When a melanocyte gets exposed to UV rays (ie the sun) it secretes melanin, and puts it into little packages (vesicles) called melanosomes. It delivers the melanosomes to the surrounding keratinocytes, which break them open with lysosomes to release the melanin into their cytoplasm. The melanin then goes to surround the nucleus of the cells, and protect its DNA from any more UV light. If you look at cells with lots of melanin vs. cells with little melanin under a microscope, you will notice that the cells with lots of melanin have very dark nuclei.

How does the router protects the network from harmful and malicious files?
Usual routers do not have such protection. But you can use router's firewall to protect some well known ports and attacks with well known patterns.
What is the pigment that colors the skin?
Melanin is the pigment inside skin cells.melanocytes produce melanin of which there are two types; pheomelanin (red) and eumelanin (very dark brown). it can get very complex, but those are the basicsLizzy the guru - the above is correct, but to add a little more, these melanocyte cells have prominent characteristics or traits (known as phenotypes).We understand these traits ensure their responsibility for our skin and hair's pigmentation allowing enough melanin production to provide protection from damage by ultraviolet radiation (sunlight).As we continue to study the role of melanin and pigmentation, it is hoped that skin Biology will lead us to understand skin diseases, particularly skin cancer.
