Explanation:

In neuroscience (a subfield of Biology, which is under Natural Science), the "all - or - none" principle describes that once an electrical impulse (action potential) in a neuron reaches its threshold, it will either fire at full intensity or not fire at all, and this intensity is maintained along the axon. So the blanks should be filled with "All" and "None" to complete the "all - or - none" principle phrase.

Answer:

All - or - None
