Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.

Answer:
Cellular division causes organisms to grow primarily by increasing "the number of cells in an organism."
Explanation:
The parent cell is also making a copy of its DNA to share equally between the two daughter cells. The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
