Identify the most common graph types,

circle graphs—illustrate how a part relates to a whole

bar graphs—compare quantities among groups and show large changes over time

histograms—show the distribution and frequency for a set of data values

line graphs—display small changes and patterns in data as well as compare two sets of data

scatter plots—help identify a possible relationship between two groups of numerical data

Explanation:

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.
