What else can I help you with?
How can black people blush?
Yea they can, they just tend to have darker skin due to more mellanin i think it's called, that controls skin pigmentation. You can tell better by looking at a lighter skinned black person. But yea basically they do, we all do.
If being in the sun makes your skin dark does being in the dark makes your skin lighter?
Depending on your genes, you can lose the amount of mellanin (skin pigmentation) over time due to a lack of Vitamin D which is what your body makes from the sunlight. Places like Iceland/Greenland I have read have to use lights similar to tanning beds in order to get the necessary light. Everyone requires some light for their body to function.
Steps to look like Michael Jackson?
By remembering that when people lie to you, or their actions don't match their words that you have no more reason to listen to them.By always seeking the most beautiful things you can find, and working to have them in a way you can share with others.By making hard work look so easy that others think it was easy and hate you.
What protects you for from ultraviolet radiation?
There is a pigment that our skin produces, called 'melanin' (you've probably heard of it) which has this special role. This protein is created by cells called melanocytes when DNA damage is detected. These melanocytes have a few protruding arms which attach to basal cells, which are particularly susceptible to the harmful effects of UV radiation. So when our skin is exposed to UV light, such as in sunlight, the DNA in these basal cells may be damaged, causing them to send distress signals to the melanocytes through its attachments, which then results in the melanocyte increasing its production of melanin which it releases into the skin to try to shield these cells from further damage. Since melanin in humans is a yellow-brown colour, this increased production results in a diffuse pigmentation we know as a tan, or may occur in more localised defined areas such as in freckles and moles. Remember: A 'holiday tan' is a sign of excess rapid sun exposure, and a symptom of DNA damage. It is the direct result of the skin working incredibly hard to protect the body against harmful UV radiation, the effects of which may damage DNA to the extent that dangerous cancers such as melanoma may occur. Be careful in the sun!
