Question

The follicle matures; the lining of the uterus begins to build again in response to increasing estrogen levels, preparing for potential implantation if fertilization occurs, while the maturing follicle in the ovary readies an egg for release during ovulation.

Answer 1

The description refers to the menstrual cycle's follicular phase and subsequent stages, including ovulation, and is part of a high school biology curriculum.

Step-by-step explanation:

The process described pertains to the menstrual cycle, which includes the follicular phase, ovulation, and potential fertilization. During the follicular phase in the ovary, follicles grow under the influence of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), with one dominant follicle maturing an egg for release. This growing follicle releases estrogen and low levels of progesterone, leading to the thickening of the endometrium in the uterus.

Upon ovulation, the mature egg is released and travels through the fallopian tube where it may meet sperm and become fertilized, forming a structure called the morula. If fertilization does not occur, the endometrial lining is eventually shed during menstruation. Following ovulation, the cycle enters the luteal phase where the ruptured follicle develops into a corpus luteum, secreting both estrogen and higher levels of progesterone to further prepare the uterus for potential implantation.
