How many contractions per minute were required for the paramecium to maintain a relatively stable internal solute concentration
and stay the same size? Think and answer: How might a paramecium maintain its volume in a slightly hypertonic solution?
Question: How does a paramecium respond to changing solute concentrations?
1. Form a hypothesis: How do you think the number of contractile vacuole contractions will change
when the water solute concentration is reduced? Please explain.
abt 24 contraction per min is needed to maintain a relatively stable internal solute conc.
paramecium maintain its volume by preventing itself from shrinking by holding in as much water as it can.
When the water solute concentration is reduced, the number of vacuole contractions will increase. But when the water solute concentrations rise, the number of vacuole contraction will decrease.
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.
