Answer:
When light hits CRY2, it changes shape and binds to its natural partner protein, known as CIB1. When light shines on the cells, the CRY2 protein binds to CIB1, which is floating in the cell. CIB1 brings along a gene activator, which initiates transcription, or the copying of DNA into mRNA.

This question uses weighted averages.
Since the average mass of element A is 63.6 amu and the only two isotopes are 63 and 65,
63.6 = x% * 63 + (1-x%) * 65
If you don't want to calculate this (like me), you can look at the answer choices.
If it was 100% A-63, the weight would be 63. Cross off D.
If it was 50/50, the weight would be 64. Cross off C.
So since the weighted average is 63.6, you would expect there to be more A-63 than A-65, so B is the only answer that makes sense.
I would say B... ultraviolet rays cause sun burns
