The circulatory system circulates blood around the body. The blood passes through the lungs, where it loses carbon dioxide and gains oxygen. All cells need oxygen to function and carbon dioxide is a form of waste produced in the cells. The digestive system breaks down food and absorbs.

The leaf surface area is just as, if not more, important than the intensity of light in photosynthesis.
nikdorinn [45]
The answer is a. True.

The photosynthesis occurs in leaves, which absorb sunlight. But the amount of absorbed sunlight by leaves depends on both the leaf surface area and intensity of life. So, t<span>he leaf surface area is just as important as the intensity of light in photosynthesis. But, if we take into consideration other leaves' functions, such as gas exchange, then the intensity of light has no effect on it. Thus, in that case, the leaf surface area is more </span><span>important than the intensity of light.</span>

MatroZZZ [7]

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.
