Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of a solvent, typically water, across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Identify the substances listed in the problem: Glucose, Salt, Water, and Oxygen.
Recognize that osmosis specifically involves the movement of water molecules, not solutes like glucose or salt, nor gases like oxygen.
Recall that a semipermeable membrane allows only certain molecules, such as water, to pass through while blocking others.
Conclude that the correct answer to the question 'Osmosis is the diffusion of what substance across a semipermeable membrane?' is Water.
