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.

True
Explanation - A hypothesis is given once the question is identified and background research has been done. A hypothesis is validated by performing experiments.
Prior to the experiments being performed, proper planning is done. After the experiment is carried out, the data is noted. Once the data is noted, results are inferred.
If the evidence agrees with the prediction then the hypothesis is being supported and validated. If the result fails to validate the hypothesis then the hypothesis need to be abandoned or modified.
