Red blood cells placed in a 0.3m urea solution urea is permeable will exhibit?
Daisyduke2
The urea entering the cell will cause an osmotic imbalance causing water to follow it into the cell. When a large amount of water enters the cell is heamolysed causing a colour change. Urea can't be permiable it is a chemical and doesn't have a cell membrane perhaps you are asking if urea can permiate RBC's or perhaps you mean to ask if RBC's are permiable to urea at this concentration?

Crenation occurs when a blood cell is placed in a?
Hypotonic solution
Would red blood cells exhibit hemolysis or crenation in a 5.0 percent solution of glucose?
neither!
What will happen to human red blood cells if they are placed in the ringer solution?
_crenate
If an erythrocyte is placed in a hypertonic solution what will it do?
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.
What would happen to a red blood cell if placed in distilled water without any solution?
no
What happens to red blood cells when they are placed in the solution that has higher water potential?
they absorb water through the permeable membrane and on ovr absorbing...they burst up
How is Osmosis in red blood cells?
Osmosis is the diffusion of molecules from where they are abundant to where they are scarce through a semi permeable membrane. In red blood cells, this semi permeable membrane is the cell membrane. If red blood cells were placed in a solution abundant with water molecules, they would diffuse into the cells through the membrane
Crenation occurs when blood is placed in a?
hypertonic solution
Crenation occurs when a blood cell is placed in a?
Hypotonic solution
What will happen if a red blood cell is placed in 50 percent NaCl solution?
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.
Would red blood cells exhibit hemolysis or crenation in a 5.0 percent solution of glucose?
neither!
Hemolysis may occur when a blood cell is placed into what?
hypotonic solution
Shape and size of red blood cell when put in slty solution?
A red blood cell when placed in salty solution shrinks and becomes wrinkled.
How would red blood cell behave in hypertonic solution?
Placed in a hypertonic solution(lower water potential), the red blood cell cytoplasm contains a solution of higher water concentration. Hence water molecules move by osmosis from the red blood cell through its selectively permeable membrane to the hypertonic solution.
What will happen to human red blood cells if they are placed in the ringer solution?
_crenate
Which blood vessel is permeable?
Only capillaries have permeable walls; veins and arteries are not permeable.

The reason for this is because a hypotonic solution has a higher osmotic pressure compared to the cytoplasm of the red blood cell.
