I. Poor scale, wasted space

III. No units for dependent variable

Explanation:

Given

See attachment for graph

Required

Identify the mistakes

The mistakes are

(I) Poor scale

The unused space on the vertical axis is much. A better scale would have reduced the amount of unused space.

(II) There is a unit (1 minute) in the independent variable; so, this is not a mistake

(III) No unit on the dependent variable

Yes, this is part of the mistake, as there is no units on the x-axis

(IV) Decimals

This is not a compulsory requirement of plotting graphs; so, this is also not a mistake

Hence,

Hence (I) and (III) are mistakes on the graph

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.
