Solution A is hyperosmotic to solution B. If solution A is separatedfrom solution B by a selectively permeable membrane, does watermove from solution A into solution B, or vice versa? Explain
the concentraiton of partleces in a hyperosmotic solution is greater than in a hypoosmotic solution true or false?
What among the following describes osmosis 1. The diffusion of water from an area low solute concentration to an area of high solute concentration. 2. Osmotic pressure is the force that allows water to move by osmosis through a selectively permeable membrane 3. When a cell is immersed in a hypertonic solution, water enters the cell by osmosis which causes it to swell and eventually burst. 4.
