|
|
if a red blood cell is placed in a hypotonic solutions it will
|
Hemolyze

|
|
If a cell is at 9% concentration of Naci |
the cell is hypotonic to the solution the solution is hypertonic to the cell
|
|
|
what changes the rate of osmosis
|
it isnot at a constant rate and is changed by heat , concentration of solutes and temp
|
|

|
Yes
|
|
|
can a hemolyzed cell become whole again
|
no
|
|
|
Given that NaCI 58 ci weigh and that 0.9% solution means that 0.9 grams are added to 100ml water
