Final answer:

The all-or-none-response does not mean that a subthreshold stimulus can never stimulate a nerve.

Step-by-step explanation:

The statement 'The all-or-none-response means that a subthreshold stimulus can never stimulate a nerve.' is False.

The all-or-none-response refers to the characteristic of an action potential in a neuron. It means that once the threshold is reached, the neuron will fire an action potential at its full strength. However, a subthreshold stimulus can still generate a graded potential, which is a small change in the membrane potential that does not reach the threshold for an action potential. So while a subthreshold stimulus may not stimulate a nerve to fire an action potential, it can still have an effect on the neuron's membrane potential.
