Question

Fertilization normally takes place:

a) in the fallopian tube
b) in the uterus
c) in the vagina
d) in the ovary from which the egg was released

Answer 1

Fertilization normally takes place in the fallopian tube above the ovary, where sperm swim through the female reproductive system to reach the egg. The secondary oocyte promotes fertilization by releasing molecules that guide the sperm and allow the attachment of the egg to the sperm's surface.

Step-by-step explanation:

Fertilization normally takes place in the fallopian tube, specifically in the part of the tube that passes above the ovary. Sperm must travel from the vagina, through the cervical canal, into the uterus, and then through the fallopian tube to reach the egg. Once sperm enters the fallopian tube, it is guided by tubular fluids and the secondary oocyte releases molecules that allow the egg to attach to the sperm's surface. The fertilization process occurs when the egg absorbs the sperm.
