Astimulus has opened the voltage-gated sodium channels in an area of a neuron's plasma membrane. as a result, rushes into the neuron and diffuses to adjacent areas; this in turn results in the in the adjacent areas

The answer to this question would be: sodium; opening of voltage-gated sodium channels

When the membrane potential rises above the threshold, the natrium voltage-gated sodium channels will be opened. This will allow the movement of sodium to the cells. Because the concentration of sodium outside the cell is much higher than inside the cells, the sodium will flow into the cells. 

Volcanoes make new rocks so not ahotspots are the the stuff that makes volcanoes mid atlantic ridge(mar cause i’m lazy) is a constructive plate boundary so it makes sense that new rocks would be found near it, also the mar is in the middle of the ocean so it fits the description deep ocean trench, umm, there’s no ocean trenches to where you’re goingso the mar is most likely the answeri wouldn’t trust me but hey why not

The fact that the female was seizing before my arrival would be the most useful information for providers, as they can already see that she is unresponsive and barely breathing upon their arrival.
