Question

osmosis can be described as...
moving with the concentration gradient.
requiring a semipermeable membrane.
all of these.
only involving the movement of water.

Explanation:

• Osmosis is the movement of water molecules from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration) across a semi - permeable membrane. This means it moves with the concentration gradient (of water).
• A semi - permeable membrane is essential for osmosis as it allows water molecules to pass through while restricting the movement of solute particles in many cases.
• And by definition, osmosis specifically involves the movement of water.

Answer:

C. all of these.
