What is the best description of osmosis?

-chemistry and biology. The process of which molecules of water or another solvent tend to pass though a semi-permeable membrane into a region of greater solute concentration, so as to make the concentrations on the two sides of the membrane more nearly equal.
-the process of gradual or unconscious assimilation of ideas, knowledge, etc..
Both of these are accurate, I hope they are possible choices, I hope this helps.
