WebWhen two solutions differ in osmolarity, the solution with higher concentration of solute is called hypertonic, while the more dilute solution is called hypotonic. If a semipermeable membrane separates such solutions, the flow of water (osmosis) takes place from a hypotonic solution to a hypertonic one. Osmoconformers vs Osmoregulators Web16 jun. 2024 · The key to their problem is osmoregulation – active regulation of the osmotic pressure to maintain the fluid balance and concentration of salts [1]. Let first take a look at freshwater fishes. Because the salt concentration inside their body is higher as in the surrounding water, water enters the body due to osmosis.
