The following statement is a(n) what do customers feel is a fair price for the new product?
hypothesis
problem
experiment
theory

Explanation:

It's a problem - a problem originates when a question is asked. In this case, we have come up with a problem that needs a solution:

1. - We'll experiment in order to come up with a hypothesis (a not-valid-yet answer of what the solution to our problem is).

2. - After a series of experiments that either prove or prove our hypothesis wrong, we'll be able to come up with a theory (a valid but still discussable final hypothesis of what the solution to our problem is).

C. / 3 - Problem.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
