Meiosis is a form of the mobile department in sexually reproducing organisms that reduces the number of chromosomes in gametes (the intercourse cells, or egg and sperm).
Meiosis is responsible for the formation of sex cells or gametes which are chargeable for sexual reproduction. It turns on the genetic information for the improvement of intercourse cells and deactivates the sporophytic information.
Seeing that cellular division takes place twice at some point of meiosis, one beginning cellular can produce <u>4 gametes</u> (eggs or sperm). In every spherical division, cells go through 4 ranges: prophase, metaphase, anaphase, and telophase.

Answer:
Negative; Estrogens and progesterone
Contraceptive pills mimic the negative feedback effect of estrogens and progesterone.
Explanation:
- <em><u>Estrogens and progesterone are regulated by negative feedback mechanisms, and therefore, birth control pills make use of this fact.</u></em>
- <em><u>Birth controls pills adds extra amount of estrogen and progesterone which inhibits the release of these hormones by the body.</u></em>
- Consequently the release of an egg from the ovary is inhibited and the lining of the uterus is made to become thin and unsuitable for pregnancy by the absence of progesterone hence decrease the secretion of the luteinizing hormone and the follicle stimulating hormone by negative feedback.This process ends up inhibiting ovulation.
It contains a cellular membrane which separates the interior of the cell from its environment.
Answer:
L. E, F, G, H, I, J, K, D, C, B.
Explanation:
L is the oldest layer because it is present below all of the layers followed by E layer then F, G, H, I, J, K, D, C and B. B is the youngest layer because it is present above of all layers and formed recently. the layers formed after B layer is C layer which is younger than the rest of the layers but older than B layer. D layer is also older than C and B layer but older than the remaining layers.
