To create a good and authentic replica of an object, there is to be a skilled artisan or forger to create the same authentic experience that the original object provides. This process takes time and much money to be done correctly for museum standards.
Asker's rating. Report Abuse. A threshold potential is the level at which an action potential will fire. For example, if a cell has a resting membrane potential of -90mEV, and the threshold potential is -60mEV, a stimulus must depolarize the membrane by 30mEV to cause the action potential to fire.
An action potential is a very rapid change in membrane potential that occurs when a nerve cell membrane is stimulated. Specifically, the membrane potential goes from the resting potential (typically -70 mV) to some positive value (typically about +30 mV) in a very short period of time (just a few milliseconds).
