1. If an immature egg cell had 20 chromosomes, the mature egg would have (???) chromosomes
A) 5
B) 10
C) 20
D) 40
I think it's D, but I'm honestly, not sure.
2. Assume a cell has 1500 mitochondria. How many will it have after telophase?
A) 1500
B) 750
C) 3000
D) 0
In both cases,the number is constant.
To find the answer to these questions, let's break down the process.
1. If an immature egg cell had 20 chromosomes, the mature egg cell would also have 20 chromosomes. The number of chromosomes remains the same throughout the maturation process, specifically in the process of meiosis.
So, the answer to question 1 is C) 20.
2. To determine the number of mitochondria after telophase, we need to understand the stages of cell division. Telophase is the last stage of mitosis or meiosis when the cell is in the process of dividing. During telophase, the nucleus of the cell reforms and the cytoplasm begins to divide. However, the number of mitochondria does not change during cell division.
Therefore, the answer to question 2 is A) 1500. After telophase, the cell would still have 1500 mitochondria.
