Question

crenation takes place when a cell is placed in _______. answer a hypertonic solution an isotonic solution a physiological saline solution a hypotonic solution i dont know yet

Explanation:

Crenation is the shrinking of a cell due to water loss. In a hypertonic solution, the solute concentration outside the cell is higher than inside, so water moves out of the cell, causing crenation. An isotonic solution has equal solute concentration, so no net water movement. Physiological saline is isotonic to human cells. A hypotonic solution has lower outside solute concentration, so water moves into the cell (causing lysis, not crenation).

Answer:

A. a hypertonic solution
