Detailed explanation-1: -When a red blood cell is placed in a hypotonic solution, there will be a net movement of free water into the cell. This situation will result in an increased intracellular volume with a lower intracellular solute concentration. The solution will end up with a higher overall solute concentration.

Detailed explanation-2: -If the cell is surrounded by a hypotonic solution, the water will move into the cell due to the process of osmosis. Osmosis occurs when water moves across a membrane from an area of low osmolarity to high osmolarity. The osmolarity of a solution indicates the concentration of the dissolved solutes within the solution.

Detailed explanation-3: -If placed in a hypotonic solution, water molecule s will enter the cell, causing it to swell and burst.

Detailed explanation-4: -Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.

Detailed explanation-5: -A hypertonic solution has fewer water molecules than a hypotonic solution, which have more water molecules. In the presence of a partially permeable membrane, water molecules will therefore move from the hypotonic solution to a hypertonic solution due to the existing differences in the concentration gradient.
