_crenate
no
The water from the cytoplasm within the red blood cell will move out of the cell into the environment and the cell itself will shrivel up.
Hypotonic solution
In isotonic solution nothing ail happen. In hypertonic solution fluid will leave the cell to dilute the external fluid, causing the cell to crenate. In Hypotonic solution fluid will move into the cell to dilute the contents of the cell, causing it to bust or haemolyse.
If a human red blood cell is placed in a hypotonic environment, the red blood cell will swell and eventually burst. The reason for this is because a hypotonic solution has a higher osmotic pressure compared to the cytoplasm of the red blood cell. Thus, the water from the hypotonic solution moves into the red blood cell causing it to rupture.
A red blood cell, when placed in 50% NaCl solution, will shrink as the water contained in it will be sucked into the surrounding solution doe to the osmotic pressure difference.
no
It will shrivel up and possibly die.
Water will leave the cell and the cell will shrink and shrivel.
Neither! Ringer's solution is specifically formulated to be isotonic with the body fluids of a particular taxa (ie. mammals, reptiles, teleost fishes, etc.). For example, a mammalian Ringer's solution (useful on everything from lab mouse tissues to human blood samples) is isotonic at an osmolarity of about 0.3 OsM.
The water will flow out of the cell into the hypertonic solution and the red blood cell will crenate (crush).
It would crenate (shrivel up). The water within would exit the cell to attempt to balance the excess salt concentration in the solution.
The water from the cytoplasm within the red blood cell will move out of the cell into the environment and the cell itself will shrivel up.
hypertonic solution
Hypotonic solution
If a red blood cell is placed in an isotonic solution then nothing should happen physically because an isotonic solution is one that has the same solute concentration as the red blood cell itself.
