If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is ____ compared to the cell.
A
hypertonic-
B
hypotonic
C
isotonic
Explanation: 

Detailed explanation-1: -If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is hypertonic compared to the cell. TONICITY : Tonicity is the ability of a solution to induce movement of water in and out of a cell.

Detailed explanation-2: -A hypertonic solution contains a high solute concentration with respect to cells. For example, a solution containing 10% salt is hypertonic.

Detailed explanation-3: -Final answer: When the cell when it is placed in salt solution, it will shrinks.

Detailed explanation-4: -Salt Sucks, Cells Swell Water in cells moves toward the highest concentration of salt. If there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size, swelling up as the water fills the cell in its imperative to combine with the salt.

Detailed explanation-5: -Salt in that example would be a hypertonic solution.
