The structures that receive the ovulated oocyte, providing a site for fertilization, are called the ________.
Neporo4naja [7]

Answer: B. fallopian tubes  

Explanation:

Fallopian tubes - consist of two channels that are located laterally to the uterine horns, and are responsible for capturing the female gamete released by the ovary into the peritoneal cavity, and its conduction to the uterus. For this, the tubes perform peristaltic movements and have eyelashes that push the gametes to the uterus. The fallopian tubes are attached to the upper part of the broad ligament, which is called mesosalpinx.

The sperm meets the ovum in the fallopian tube, and then they go into the uterine cavity. When this does not occur, there is an ectopic pregnancy because the development of the fetus occurs in the tube's ampoule, a phenomenon known as tubal pregnancy, which can culminate in the rupture of the fallopian tube, a situation that causes major bleeding.

A biosphere is that portion of the earth where life occurs which means it consists of water, underground, land, and air. On earth, life can be seen at the bottom of the ocean to 9 km above the earth.
