The process you observed of the egg becoming smaller or larger in the different solutions was due to osmosis. Which of the following is true about osmosis? Select one or more: a. Osmosis is a form of active transport, in which water moves from a solution of low solute concentration to a solution of higher solute concentration b. Osmosis is a form of passive transport, in which water moves only when the concentration of solutes is equal in each solution c. Osmosis is a form of passive transport, in which water moves from a solution of low solute concentration to a solution of higher solute concentration d. Osmosis is a form of active transport, in which water moves from a solution of high solute concentration to a solution of lower solute concentration e. Osmosis is a form of passive transport, in which water moves from a solution of high solute concentration to a solution of lower solute concentration
Would water molecules move faster when there is a high concentartion gradient or low concentartion gradient? I think basically this question is asking if water molecules will move faster using passive transport or active transport? since it involves water molecules wouldn't it be passive transport since osmosis is a type of passive transport? I'm confused
