Answer:
The number of cell divisions is too large to even estimate.
Explanation:
Think, for every cell to be formed, a parent cell needed to divide. on top of that, for every parent cell is the result of another parent cell. Think of how small a cell is, and think of how many cells are in the onion. The fact that onions are still onions is incredible, because a DNA mutation occurs at a very high rate during cell division. When DNA divides, it sometimes doesn't divide evenly, resulting in too much DNA is one cell, and not enough in another. Science has proven that the composition of DNA is what makes humans humans, trees trees, and onions onions. The fact that onions have withstood the millions upon millions of DNA mutations while still remaining a species, is astonishing.

<span>Explanation: Oxygen is the more electro-negative of the atoms in the water molecule, so it tends to pull the 'shared' electron more to itself. Thus, the oxygen atom has a greater time-share of all electrons, and therefore the hydrogen atoms are more positive for a partial lack of electrons</span>

Answer: Birds pick up oil on their beaks, by rubbing against the uropygial or preen gland near the tail, and then rub it over their feathers. This makes the water unable to break through the oil.
