Define osmotic pressures. osmotic pressures synonyms, osmotic pressures pronunciation, osmotic pressures translation, English dictionary definition of osmotic pressures. n. The pressure exerted by the flow of water through a semipermeable membrane separa
Osmotic pressure is one of the most important chemical concepts used in medicine. Despite this it is a topic which is very frequently misunderstood by both nurses and medical students. It is perhaps best to begin this discussion by describing an extremely simple experiment....

摘要: The influence of salinity/ osmotic pressure on the wood-rotting ability of marine and terrestrial fungi was investigated using vermiculite burial and wood block weight loss estimation techniques.关键词: decay fungi, Cladosporium herbarum, marine fungi, wood preservation, Alternaria, Stachybotrys ...
The external pressure can be regulated to prevent the osmosis of water into the solution. Another definition of osmotic pressure can be found here. The external pressure applied to a solution in order to stop the osmosis of solvent into a solution separated by a semipermeable membrane is known ...
Which of the following is wrong about ADH? A、released by the neurohypophysis B、increase the permeability of distal tubules and collecting duct epithelial cells to water C、Plasma colloid osmotic pressure Increases, which stimulates osmotic pressure receptors to increase secretion D、When the large ...
The melanophores of the fiddler crab, Uca pugnax, are sensitive to changes in osmotic pressure. Hypotonic solutions induce a reversible melanin dispersion. The degree of response to the melanin-dispersing principle from the sinus gland also depends to some extent upon osmotic pressure. The melanin-...
