If the sperm cell fertilises the ovum, and implantation does not occur, then the corpus luteum degenerates and it turns into corpus albicans, stopping progesterone secretion. If fertilisation occurs and implantation also, the syncytiotrophoblast, the "root part" of the blastocyst (one of the early structures originated from the zygote), produces a hormone that is called <span>human chorionic gonadotropin (hCG). The hCG is what makes the corpus luteum keep secreting progesterone and maintain itself. The progesterone will then help keep the endometrium and, therefore, allow the development of the embryo to happen.</span>
Answer:
Percentage of food eaten by the flock
Why is the percentage of food eaten a good number to use? Explanation:
A percentage compares the number of birds in the flock to the total number of birds in all flocks.
If the percentage is high, the flock is more successful, so the flock should grow.
If the percentage is low, the flock is struggling to eat, so the flock should shrink.
