A red blood cell has a salt concentration of 0.9%. What will happen if it is placed into
a 0.8% salt solution? The red blood cell will
burst
remain the same
shrink then grow
shrink

Respuesta :

Answer:

Shrink

Explanation:

The blood cell would shrink because of osmosis. The molecules move with the concentration gradient so water molecules will move outside of the cell where there is less water than inside of the cell.

Blood cells are the main constituents of the circulatory system and carry the most vital function of oxygen transportation. Blood cells have a specific concentration and osmotic pressure to remain vital.

The correct answer is:

Option D. Shrink.

This can be explained as:

  • Cells have a tendency to shrink in hypertonic solutions while swells in hypotonic solutions.

  • 0.8% of the salt solution will act as a hypertonic solution and the RBC placed in it will shrink.

  • When cells are placed in hypertonic solution it loses their water content to the outside surface and hence shrink.

Therefore when the red blood cells are placed in 0.8% salt solution they will shrink.
