Osmosis can be defined as diffusion of:
Osmosis can be defined as diffusion of:
- A) water molecules from an area of his concentration to an area of low concentration
- B) water molecules from a dilute solution to a concentrated solution across a permeable membrane
- C) water molecules from a concentrated solution a dilute solution through a semi permeable membrane
- D) water molecules form a dilute solution to a concentrated solution through a semi permeable membrane
Correct Answer: D) water molecules form a dilute solution to a concentrated solution through a semi permeable membrane
Explanation
This Biology question is about osmosis, which is the movement of water molecules across a semi-permeable membrane. Osmosis occurs when water moves from an area of high concentration to an area of low concentration. The question is asking which option correctly describes the diffusion of water molecules during osmosis. Option A states that water molecules move from an area of high concentration to an area of low concentration, but this is the definition of simple diffusion, not osmosis. Option B correctly describes osmosis. Water molecules move from a dilute solution to a concentrated solution across a semi-permeable membrane. Option C describes the opposite of osmosis. Water molecules move from a concentrated solution to a dilute solution through a semi-permeable membrane. Option D correctly describes osmosis. Water molecules move from a dilute solution to a concentrated solution through a semi-permeable membrane. Therefore, the correct answer to this question is Option D.
