Answer: The correct answer would be corpus albicans.
Explanation:
After ovulation, the ovarian follicle converts into corpus hemorrhagicum. After some time, it converts into a temporary endocrine structure termed as corpus luteum. It maintains high levels of progesterone which is necessary for maintenance of uterus lining.
However, in absence of pregnancy or fertilisation, the corpus luteum starts degrading and convert into the structure termed as corpus albicans.
Answer:
True.
Explanation:
There are four phases which occur during karyokinesis, these are -
- Prophase
- Metaphase
- Anaphase
- Telophase
Telophase is the last phase of karyokinesis. The main events that occur during telophase are-
- Uncoiling of chromosome occurs
- Chromatin is formed
- Spindle breaks down
- Nuclear membrane or nuclear envelope if reformed
Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
I haven't done biology in a long time but I am almost certain it is called a acrocentric chromosome.
