Question

question 11 1 pts each beaker below shows a red blood cell in a different external environment. match the beaker with the correct explanation for the appearance of the blood cell. a b c choose the cells stay the same due to an isotonic external solution the cells have swollen due to a hypertonic external solution the cells have shrunk in response to a hypotonic external solution the cells have shrunk in response to a hypertonic external solution the cells have swollen due to a hypotonic external solution

Explanation:

Osmosis is the key concept here. In an isotonic solution, there is no net movement of water, so cell size stays the same. In a hypertonic solution, water moves out of the cell causing it to shrink. In a hypotonic solution, water moves into the cell causing it to swell.

Answer:

• If the cell stays the same: The cells stay the same due to an isotonic external solution
• If the cell has swollen: The cells have swollen due to a hypotonic external solution
• If the cell has shrunk: The cells have shrunk in response to a hypertonic external solution
