Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.
Osmosis is much like simple diffusion but it specifically describes the movement of water (not the solute) across a selectively permeable membrane until there is an equal concentration of water and solute on both sides of the membrane. Simple diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy.
D) osmosis. C) diffusion. Select the correct statement about the pharynx. A) The pharyngeal tonsil is located in the laryngopharynx. B) The palatine tonsils are embedded in the lateral walls of the nasopharynx. C) The laryngopharynx blends posteriorly into the nasopharynx. D) The pharyngotympanic (auditory) tube drains into the nasopharynx.
(Correct Answer Below). Reveal the answer to this question whenever you are ready. B) If a cell is placed in an isotonic solution, more water will enter the cell than leaves the cell. C) Osmosis is the diffusion of water from a region of lower water concentration to a region of higher water concentration.
