Answer:
This is because the voltage gated sodium channels which opens for the influx of sodium ions, which caused increased postivity of the axoplasm closed, with simultaneous opening of potassium channels.
Therefore depolarization stopped, thus propagation and transmission of action potential (caused by depolarization) which cause the reversal of charges in the membrane (making the axoplasm more negative) for the voltage rise to 40mV also stopped.
In addition the simultaneous opening of voltage gated potassium channels caused K+ to leave the axoplasm to the external environments. This makes the inner membrane to be negative further lowering the potential, to -75mv. This is re-polarization.

The exoskeleton of crayfish is an adaptive advantage to crayfish because it gives it support and protection. A crayfish exoskeleton is the tough external material, made from chitin and calcium carbonate that envelops crayfish body. Also, the color of exoskeleton matches to the environment where the crayfish lives, this it is more difficult to find the crawfish (protection from predators and camouflages for finding the prey).
Crayfish shed their exoskeletons a few times per year in a process called molting.
Sounds to me that Gracie discovered<span> fermentation, acid is produced giving the sour taste and CO2 is produced too. Some grapes have yeast on them to start fermentation</span>
