Question

There are two types of cell division: Mitosis and Meiosis. Most of the time when people refer to "cell division," they mean Mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During Mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of Mitosis are carefully controlled by a number of genes.

Answer 1

When Mitosis is not regulated correctly, health problems such as cancer can result. The other type of cell division, Meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half-from 46 to 23-to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes, so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of DNA shuffling while the cells are dividing. The passage is a review of Mitosis and Meiosis. Answer the following: a. What is one way Mitosis and Meiosis are similar? b. A human skin cell has 46 chromosomes. After Mitosis, how many chromosomes will each new skin cell have? c. What types of cells are produced from Meiosis?

Answer 2

Im not sure about A. But I think B is 46 and C is egg and sperm cells(gametes)

Answer 3

B and C are correct, I believe. (Just studied that at Advanced academics, and got an A- in the class) and A would be they are similar in that most of the steps are similar. They both divide and most of both steps are similar (As in they divide similarly, with just a few minor differences).

Answer 4

Thanks!
