The skins major functions include all but which of the following?
a. physical protection from abrasions and damage
b. protection from microbes
c. protection from uv radiation
d. prevent absorbtions of chemicals.

Well the most appropriate answer is C, the skin layer is a layer of cells. These layers are constantly subject to the UV spectrum in which causes DNA thimer dimerisation to occur. This leads to DNA damage and thus cancer.

I guess D makes sense in that some chemicals cannot be absorbed (charged chemicals)
