Q:

Tanning in the sun is often associated with the sensation of heat on the skin. This sensation is similar to the sensation when close to a hot fire or oven. Yet, the hot fire and oven do not induce the same changes in skin coloration. The fact that fires and ovens do not darken the skin is primarily due to the fact that

A

One does not expose him or herself to fires and ovens as long as to the sun; this is the only reason why the skin does not get dark. If one were to expose him or herself for a longer period of time, the same effects would be seen as if one had been in the sun.

B

Fires and ovens do not emit enough infrared radiation to induce the changes necessary to darken skin color.

C

Fires and ovens are not hot enough to induce color changes in skin.

D

Fires and ovens do not emit the correct wavelength of electromagnetic radiation to induce the chemical changes in the skin to darken it.
