A bird species requires abundant shoreline and a high population of insects within its habitat. You observe a population of these birds with a low density and adequate resources, but the population seems to be growing very slowly. What might be an explanation for the
slow population growth?

answer: - b cells

explanation: -

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

whats the answer to your question?
