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.
Answer:
The two factors are: moderate temperature and energy source.
Explanation:
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.
The two major factors that confine living thing to the biosphere is the energy source and moderate temperature. Energy is required by all the organisms present on the earth. Every organism has its own way to gain energy like some gain energy from the sun and some from consuming others.
Moderate and constant temperature is important for the survival of the organisms and to maintain homeostasis in them.
