Question

A cell placed in a 9% saline solution (molecular weight = 58.5g) would

A. lyse.
B. crenate.
C. not change.
D. swell.

Answer 1

A cell placed in a 9% saline solution (molecular weight = 58.5g) would swell due to water gain.

Step-by-step explanation:

A cell placed in a 9% saline solution (molecular weight = 58.5g) would swell due to water gain. The saline solution is hypotonic compared to the cell, meaning it has a lower solute concentration. In this hypotonic solution, water particles will move into the cell, causing it to expand and eventually lyse (burst).
