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.
Answer:
uniformitarianism, Fossil groups, 48 million years ago.
Explanation:

Order:
1) A substrate enters the active site of enzyme.
2) The enzyme and substrate bind to form an enzyme substrate complex.
3) The chemical reaction occurs
4) New substances called ‘products’ are formed.
