If a cell bathed in a salt solution loses mass, the osmolarity of the cell would be ____ to the solution
|
|
hypertonic
|
|
|
hypotonic
|
|
|
equal
|
|
|
cannot be determined
|
Explanation:
Detailed explanation-1: -When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Detailed explanation-2: -The cell shrinks in response. A solution of low solute concentration is referred to as hypotonic. A solution containing 0.5% salt is hypotonic with respect to the cell.
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 solutions have an osmolality lower than the body (< 280 mOsmol/l) which actively promotes fluid absorption.
