Solution
The answer is the second one (Osmosis): the process by which solvent flows through a semipermeable membrane from a dilute (hypotonic) solution to a concentrated (hypertonic) solution.
Explanation for each option:
Tonicity: This term refers to the relative concentration of solutes in a solution outside a cell compared to inside the cell, which affects the cell's volume and pressure. It does not describe the process of solvent movement.
Osmosis: This is the correct answer. Osmosis is the movement of solvent molecules through a semipermeable membrane from a region of lower solute concentration (hypotonic) to a region of higher solute concentration (hypertonic).
Dilution: This term refers to the process of reducing the concentration of a solute in a solution, usually by adding more solvent. It does not involve the movement of solvent through a membrane.
Dialysis: This is a process where solutes and solvent are separated by a semipermeable membrane, often used in medical treatments to remove waste products from the blood. It is not specifically the process described in the question.
Summary:
Osmosis is the process by which solvent flows through a semipermeable membrane from a dilute (hypotonic) solution to a concentrated (hypertonic) solution.
