A: Yes, melanoma, or skin cancer,  is more common for people with a lower amount of melanin, because they do not have a strong melanin barrier, however anyone, no matter what race, can get skin cancer because melanin can only protect you from the sun to a certain extent.

A: The skin cells absorb the ultraviolet rays, and turns it into vitamin D which then goes into your bloodstream, kidneys, and liver.]]> 2016-09-08 15:06:42 UTC https://padlet.com/molliedl/wtimjg7oxlpq/wish/122466126 kiara_malm https://padlet.com/molliedl/wtimjg7oxlpq/wish/122616511 Q: Write out the layers of the epidermis from superficial to deep. Give a brief description of each layer. 
A: Stratum Corundum : 20-30 dead, horny layers 
Stratum Lucidium: Only in thick layers of skin 
Stratum Granulosum: grainioles 
Stratum Spinosum: Most layers; location of Keratinocyte
Stratum  Basale: Actively Miotic; location of melanocytes

Add picture and sources.
A:  People closer to the equator have a higher production of dark colored melanin, which acts like a protection barrier or an umbrella, to shield from the high amounts of solar radiation. As for the people further away from the equator, they have a much lower production of melanin because there is not as much solar radiation towards the poles. Due to the lower amount of melanin in the epidermis of people away from the equator they can collect enough sunlight to make vitamin D.

 A:Yes, Melanin affects how light or dark your skin color is. The more melanin, the darker your skin color is. The amount of melanin you have affects the amount of vitamin D you can produce. Melanin protects from too much UVB exposure, so darker skin with more melanin allow less UVB to enter. When there's less UVB getting to the skin, less vitamin D is produced. If you’re dark skinned, you need more sun exposure to make vitamin D than if you’re fair skinned.
