Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee.
Membrane
A membrane is a selective barrier; it lets some items pass but prevents others from doing so. These entities could be ions, molecules, or other tiny particles. Biological and manufactured membranes are the two broad categories into which membranes can be placed. Cell membranes, which are the exterior coverings of cells or organelles that permit the passage of specific components, nuclear membranes, which enclose the cell nucleus, and tissue membranes like mucosae and serosae are all examples of biological membranes. Humans create synthetic membranes for use in laboratories and industries (such as chemical plants).

The answer is 32 because any offspring receives an equal amount of chromosomes from the mother and the father.
From the right atrium, the deoxygenated blood drains into the right ventricle through the right atrioventricular (AV) valve, which is so named because it is between the atrium and the ventricle. This valve is also referred to as the tricuspid valve because it has three flaps in its structure. When the ventricles contract, the AV valve closes off the opening between the ventricle and the atrium so that blood does not flow back up into the atrium.As the right ventricle contracts, it forces the deoxygenated blood through the pulmonary semilunar valve and into the pulmonary artery. Semilunar means half-moon and refers to the shape of the valve. Note that this is the only artery in the body that contains deoxygenated blood; all other arteries contain oxygenated blood. The semilunar valve keeps blood from flowing back into the right ventricle once it is in the pulmonary artery.The pulmonary artery carries the blood that is very low in oxygen to the lungs, where it becomes oxygenated. i hope this helps you
