Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What direction does water flow between two solutions with different concentrations of solutes?
A
Hyper tonic to hypotonic
B
Hypotonic to hypertonic
C
isotonic to hypertonic
D
isotonic to hypotonic
Explanation: 

Detailed explanation-1: -The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.

Detailed explanation-2: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-3: -In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Detailed explanation-4: -Hypotonic solution is the one which has a comparatively lesser concentration of solutes in the solution with respect to the surrounding solution. So, it is quite obvious that the flow of water will be towards the hypertonic solution, in order to bring about isotonicity.
