Question

Multiple choice questions :
A red blood cell (RBC) was kept in a certain solut
said solution was
ma certain solution for few minutes and it got burst. The
(a) Isotonic
(b) Concentrated sugar solution
(c) Hypertonic
(d) Hypotonic​

Answer 1

Answer:

the solution was hypotonic as due to diffusion to balance the concentration the cell gets swollen n at last bursts

heya mate

hope it helps

plz mark me as brainliest answer

n follow me so that i can follow u back

Answer 2

Red blood cells burst when they are kept in Hypotonic solutions.

• Osmosis is the process by which solvent molecules of a solution move from their region of higher concentration to a region of lower concentration, through a semi-permeable membrane.
• When a red blood cell is placed in a solution containing lower water concentration (solution of 0.45% NaCl), the water moves into the cell by endosmosis and the cell swells up and may burst.
• Such a solution containing lower water potential than the solution inside the cell is called a Hypotonic solution.
• In a hypertonic solution, the water moves out of the cell, leading to it shrink.
