It could be bad habits like Smoking and Alcohol. Others can't be controlled, it could be biological (your grandparents had it, your parents, and now you) . Others could have been prevented, like being Obese, or your just not in healthy shape.
Answer:
Nutritive and varied stimulus exposure divergence
Explanation:
No doubt that Human and Eyes of fly have Pax6 conserved sequences and their primary function is highly conserved.but there is a very simple explanation for their morphological divergence. First divergence takes place where flies have totally different stimulus exposure and that continuous exposure develops a more suitable hexagonal facets by evolutionary point of view are necessary for quick motion detection. Although they can only differ between bright and dark, they don't provide a very pure vision but this is necessary for them. The ectopic expression can be explained by their different nutritive exposure over the course of their evolution.
The primary function of the Calvin cycle is to change carbon dioxide into usable energy known as glucose. So Option A.
