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.
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
