Form a hypothesis: how do you think the number of contractile vacuole contractions will change when the water solute concentration is reduced? explain why you think so.

When the number of vacuole contractions will increase, the water solute concentration is reduced. But when the water solute concentrations rise, the number of vacuole contraction will decrease. So it is cetris paribus, means when the one is increase the other one will decrease. It is always contradicting to the another one.
