Question

"The student predicted that the contractile vacuole would contract fewer times in one minute in a solution that had a higher concentration of salt than that found in typical pond water. This prediction is most likely
(1)correct, because a high concentration of salt in the environment will force water into the cell, causing the contractile vacuole to pump
(2)incorrect, because salt would be entering the cell, and the contractile vacuole would have to pump it out
(3)incorrect, because the concentration of salt in the environment should not affect a cell
(4)correct, because water would be moving out of the cell into the salt solution"

Answer 1

I think the correct answer from the choices listed above is option 4. This prediction is most likely correct, because water would be moving out of the cell into the salt solution. Hope this answers the question. Have a nice day. Feel free to ask more questions.
