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.
If the depolarisation is not great enough to reach the threshold, then an action potential (and hence an impulse) will not be produced. This is called the all or nothing law. This means that the ion channels are either open or closed; there is no half-way position. This means that the action potential always reaches +40mV as it moves along an axon, and it is never attenuated (reduced) by long axons.
