He is making a plant cell since the cell walls are box shaped, the balloon would be the large vacuole which takes up a lot of space in the cell, the marbles would be the ribosomes.

He did however noticed that there were some traits seen in the parents that were passed to the offspring in the same combination. These were termed "linked-traits" and were the first indications that genes may be linked.
Answer:
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.
