Detailed explanation-1: -The kidneys filter the blood and ensure a concentration of salt and water that allows for homeostasis within our cells. This is why if a frog egg cell is placed into a hypotonic solution, it will swell via osmosis. Also, if a red blood cell is placed in a hypotonic solution, it will bloat up and may explode.
Detailed explanation-2: -Aquaporins are channel proteins that facilitate the transport of water across the cell membrane. One group of researchers hypothesizes that without functional aquaporins, no water will be able to enter the cell.
Detailed explanation-3: -Phagocytosis. Phagocytosis (literally, “cell eating”) is a form of endocytosis in which large particles, such as cells or cellular debris, are transported into the cell.
Detailed explanation-4: -What condition might result from an excess of aquaporins? fluid retention in pregnant women ( Aquaporins transport water. An excess of aquaporins during pregnancy can result in fluid retention.) Water movement is important in urine formation in the kidneys.
