Intracellular Fluids and the Fluids Surrounding Cells in Multicellular Organisms

Intracellular fluids and the fluids surrounding cells in multicellular organisms are full of dissolved substances,including nucleotides,amino acids,proteins and ions.The total concentration of substances determines the colligative properties of a fluid.Osmosis is one of several such colligative properties.
a.Give the definition of osmosis.
b.Eukaryotic cells are aqueous solutions surrounded by semipermeable membranes.Consequently,incubation of a cell in a solution of lower osmotic pressure would cause the cell to swell up and burst.Discuss two solutions that have developed during evolution to solve this problem.
