Question

Which of the following is an example of osmoregulation?
A) the contractile vacuole of a Paramecium
B) two solutions that are isotonic
C) type 2 diabetes mellitus
D) all of the above

Accepted Answer

Osmoregulation refers to the control of water balance and solute concentrations in living organisms. The contractile vacuole of a Paramecium is an example of osmoregulation as it helps the organism maintain its water balance by pumping out excess water. Option B refers to a state where there is no osmotic pressure difference between two solutions and is not an example of osmoregulation. Option C refers to a medical condition and is not relevant to osmoregulation.
