In neuroscience, depolarization is an "all or nothing" response; what does that
Tom [10]

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

What nucleotide is used during transcription instead of thymine
