The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.
One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
Mitral valve prolapse severe enough to cause regurgitation may directly cause INCREASE pressure in the LEFT atrium. Mitral valve prolapse is a medical condition in which the the two valve flaps of the mitral valve do not close properly, bulging upward into the left atrium. The condition may be mild or severe. Heart surgery may be required in case of the severe one.
4 cells would be created after meiosis and each cell would have 7 chromosomes.
<h3>Meiosis</h3>
Meiosis is the division of non-vegetative cells. It is a reductional division during which the ploidy level of the parent cell is halved in the daughter cells.
Thus, a cell with 2n = 14 that undergoes meiosis will produce daughter cells with n = 7.
Usually, 4 daughter cells are produced at the end of meiosis.

I found the exercise on the internet and these are the options:
"<span>a. gluconeogenesis begins
b. beta-oxidation increases
c. blood glucose levels fall
d. the liver produces more glycogen"
The option that's not likely to happen is "</span>the liver produces more glycogen".
The formation of glycogen by the liver happens after eating a meal with carbohydrates. The level of blood glucose increases, and insulin is secreted by the pancreas and will act by allowing glucose to enter the body cells. When the glucose enters the liver cells, insulin will also act on the liver by stimulating glycogen synthesis. This process continues to happen until glucose levels begin to decrease in the <span>post-absorptive state</span> and, therefore, insulin secretion also decreases leading glycogen synthesis in the liver to stop.
