which of the following stimulates a secondary oocyte to become an ovum?
penetration by a sperm
luteinizing hormone (lh)
estrogen
follicle stimulating hormone (fsh)

Explanation:

During fertilization, when a sperm penetrates the secondary oocyte, it triggers the completion of meiosis II in the secondary oocyte. This process results in the formation of an ovum (mature egg) and a second polar body. Luteinizing hormone (LH) is involved in ovulation (release of the secondary oocyte from the follicle). Estrogen is mainly involved in the development of secondary - sexual characteristics and the thickening of the endometrium. Follicle - stimulating hormone (FSH) is involved in the growth and development of ovarian follicles.

Answer:

Penetration by a sperm
