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.
A change in the resting potential can affect its permeability. This is called a stimulus. if this stimulus causes a decrease from the resting potential of -70 millivolts in the direction of 0, the membrane is said to be depolarized. This creates an action potential. The action potential is an all or none event. A neuron has a threshold potential -50 millivolts, this must be attained before the sodium gates open and allow the sodium to pour into the cell.
