The concentration of cytoplasm of RBCs could be 0.5 M.
A cell placed in an isotonic solution will not shrink or swell. Isotonic means that the concentration of solutes in the solution is equal to the concentration of solutes within the cell. Since both concentrations are the same, no water flows in or out of the cell due to osmotic pressure.
hello?
A raw egg without its shell but with its inner membrane intact will either swell or shrink when placed in a solution because of the concentration gradient. The membrane is semi-permeable. An egg will shrink if it is placed in a solution that has a higher solute concentration than inside it. It will swell if it is placed in a solution that has a lower solute concentration than inside the egg.
No. An isotonic solution would not cause a cell to shrink, because the concentration of water in the solution and inside the cell is the same. A hypertonic solution would cause a cell to shrink.
Osmosis! The concentration of substances disolved in the cytoplasm is lower than the concentration of salt in salt water. The cytoplasm and the salt water are separated by the cell membrane, which is semi-permeable ie it lets water through but not dissolved substances (the membrane is also described as partially permeable or selectively permeable). So, water will pass by osmosis from the cytoplasm (the dilute solution) to the salt water (the concentrated solution), and the cell will shrink as it loses water.

If you place the cell in a hypertonic solution (a solution with a higher concentration of salt than the cell) the cell membrane would shrink.
a) place in a concentrated salt solution.
Breasts neither grow or shrink.
A hypertonic solution has more solutes than a cell, where the cell shrinks and possibly dies but a hypotonic solution, meanwhile, has less solutes than a cell where the cell expands and possibly bursts.

The cytoplasm looses water to the cell exterior.

neither. it forces it to eat.
Cells burst due to the osmotic effect. This is where the concentration of water outside the cell is greater relative to the concentration of water inside the cell. The water will flow through the cell wall and into the cytoplasm. This makes the cell turgid. If the concentration gradient is very steep, enough water will enter the cell so as to make it burst. The opposite happens if there is a greater concentration of water inside the cell - water will exit the cell and cause it to shrivel.
It is called plasmolysis. The cytoplasm and vacuole shrink but cell wall remains the same.
