Answer:
The ovarian cycle manages the preparation of endocrine tissue, and the release of eggs within the female body.
The ovarian cycle consists of a follicular phase. Gradual increases of FSH and LH stimulatethe growth of follicles on the surface of the ovary. This progression ensures that the egg is ready for ovulation. As the follicles mature, they beginto emit estrogens and maintain low levels of progesterone. Progesterone secures the endometriumto help facilitate pregnancy. The ovum takes about seven days to journey through the Fallopian tube and implant in the uterus. At this stage, the cells number around 30-60 and are identified as the morula. If pregnancy does not occur, the lining will be shed. Estrogen levels rise after roughly five days, leading the menstrual cycle into the proliferative phase. The endometrium initiates regrowth to replace the weakened blood vessels and glands from the previous cycle.

The right answer is option d as its absence would impact many organisms in the ecosystem.
Keystone species are crucial for the ecosystem's health. If such a species were to disappear from an ecosystem, it would disrupt the ecosystem's functioning, leading to significant consequences. Therefore, keystone species are vital for the ecosystem's survival.
