Why does salt effect the rate of the contractile vacuole of a paramecium?
Wiki User

The surrounding environment is no longer isotonic with the contents of the cell. Diffusion of salt molecules from low concentration to high concentration would affect the paramecium's ability to retain intact cytoplasm and organelles. The contractile vacuoles act as a defense mechanism against an either hypertonic or hypotonic situation.

What is keeps the number of paramecium at a steady level?
About 100 paramecium per every 58ml of water with a controlled environment keeps them at a rather constant growth rate if that is what you are asking.
Would Contractile vacuole discharge rate be faster or slower in salt water?
That would depend on the natural habitat of the organism. If your salt sol'n is 3% or so, a sessile org would be happy as a (shame on me) clam. A fresh water org would die. Well over 3% would slow or kill any sea-borne unicels. Please induct for yourself the corrolaries.
What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
What is the effect of atropine plus acetylcholine on frog heart?
ACh will decrease heart rate/contractile strength, etc. Atropine is a muscarinic ACh receptor (mAChR) antagonist, so blocks the effects of ACh. Adding both together will result in a weak action of ACh that tails off as all the mAChRs become blocked by Atropine.
What is the effect of temperature on the rate of evoporation?
Higher temp = higher rate of evaporation
