Study this image. Earth apostrophe s crust. Arrows show movement from middle toward opposing sides, creating a separation.

Which statement correctly explains what is happening in the image?

A volcano is forming.
Plates are converging.
A rift valley is forming.
A transform boundary is occurring.

C.) A rift valley is forming

Explanation:

Because one is a ocean plate, and one is a "land plate" and they are pulling apart, which forms a rift valley.

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.
