What will happen to the amount of prairie ecosystem if global warming and increased precipitation occur in that area?

If the temperature rise and the precipitation the vast grasslands called prairies will start to lose their initial appearance and characteristics and because of the higher temperature, humidity and rainfall trees will start to grow as well as bushes. Over time (depending on how quickly the change will appear) the prairie will be replaced by vast rainforests and the prairie ecosystem will be totally replaced by a tropical rainforest ecosystem similar to the southern half of central america.

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.
