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.
when the cell is at a resting state; the cell carries an electrical charge. Inside is negatively charged, outside is positively charged. Phase 4 (starts at -60mV): This is the spontaneous depolarization (pacemaker potential) that triggers the action potential once the membrane potential reaches threshold.
