A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton
-BARSIC- [3]

Answer:

The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".

Explanation:

0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:

A: 3.21% (m/v) NaCl Solution  = crenation (higher than 0.9% (m/v) NaCl)

B: 1.65% (m/v) glucose Solution  = hemolysis (lower than 5.0% (m/v) glucose)

C: distilled H2O Solution  = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)

D: 6.97% (m/v) glucose Solution  = crenation (higher than 5.0% (m/v) glucose)

E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)

For water to travel across the cell membrane at a substantial rate the water molecules travel through protein channels known as
Kitty [74]
The appropriate response is Facilitated Diffusion. It is the procedure of unconstrained detached transport of atoms or particles over a natural film by means of particular transmembrane indispensable proteins. 
In the cell, cases of atoms that must utilize facilitated diffusion to move all through the cell film are glucose, sodium particles, and potassium particles. They pass utilizing transporter proteins through the cell film without vitality along the fixation slope.
