How does this evidence help explain why the skin cancer rate is higher in Australia than in Brazil, even though the two countries get the same amount of sunlight?

Most people in Australia are white, their skin is more vulnerable to sunlight because of the lack of melanin in their complexion. It is harder for people in Brazil to get skin can see as most of their people contain more melanin in their skin. (i couldnt see what the evidence was so so sorry if this wasn't what you were looking for)

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.
