The all-or-none phenomenon as applied to nerve conduction states that the whole nerve cell must be stimulated for conduction to take place. true or false

True

Explanation:

Nerve impulse must reach a certain threshold in a neuron before action potential can be generated to intiate conduction of action potential.

Therefore if mutiple impulses are generated and these are not upto thresholds , no matter how strong the stimulI are-NO ACTION POTENTIAL WILL BE GENERATED.

THIS IS ALL OR NONE PRINCIPLE

The all or none hypotheses can be best explain with flushing of the water closet after using it. If required volume of water is not pumped into the water closet storage above, no matter how long the handle is push, FLUSHING WILL NOT TAKE PLACE.Thus the threshold volume of water must be met.

there are no details given

explanation:

well we can't tell you because we cant see the time give a screen shot or something.
