How do changes in the environment, interactions, and disturbances influence ecosystem stability?

it can cause  some species to freak out and move away from that. and disturbances in were other species get there food can really cause problems and could have some species die off and make that ecosystem shrink

Explanation:

hope this answer can help you :)

a time line cause it goes from 685 to 978

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.
