I think its movement of water across a membrabe
<span>they do not have specific functions. hope this helped

Water's polarity makes it an excellent solvent for salts, like sodium chloride, as other substances required by cells to carry out metabolic processes.
When there is no movement of solvent in solution then both are in isotonic soln !!
so They are in ISOTONIC solution !!
Dust in the atmosphere represents suspension. It is collaborating shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entitles. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
