WILL CROWN BRAINLIEST why are the models of solar systems that you can purchase in stores not to scale?

if they were to scale they would be huge

Distance and sizes in the solar system are difficult to visualize because the numbers are so large. In making a scale model, you need to divide the actual figure by any standard number to make a scaling factor.

Explanation:

I think tell me if im wrong

littering streams           is the answer

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.
