Table salt is made of the ionic compound sodium chloride, which consists of the chemical elements sodium and chlorine.You probably learned from unintentional play at the kitchen table as a child that if you sprinkle salt into a glass of pure water, the salt disappears after a time; the more salt you add, the longer this takes, and it may require some shaking or stirring to bring about. Free learning resources for students covering all major areas of biology. The non metalic ions of the acid and the metal ions of the base form the salt. Definition Bile salts are found in bile, a secretion produced by liver cells to aid digestion. Any of the sodium salts of the bile acids, such as taurocholate and glycocholate, occurring in bile. Here’s the definition of osmosis that you will see in most text books: In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane. The negative oxygen atoms attract the positive sodium (Na +), and the positive hydrogen atoms … hypertonic solution one having an osmotic pressure greater than that of a standard of reference. Fish are found in both fresh and salt water worldwide, and are a very important food source for many nations. Literature of interest. Osmosis is the chemical process of diffusion, involving the transfer of solvent with a lower concentration of a certain solute through a semipermeable membrane, and into the area containing a higher concentration of that solute. The freshwater biome. Want to thank TFD for its existence? To tolerate/exclude excessive salts within/from the cells, different strategies are developed by salt-tolerant species (Parida and Das, 2005). As such, when cells are submerged in salt water, water moves out of the cell into the salt … It only takes a minute to sign up.
