Earth’s climate is warming up because of factors like pollution. How much has the Earth’s climate warmed over the last 100 years?

A) 0.1 C
B) 0.5 C
C) 1.0 C
D) 1.5 C

C.

Explanation:

I would say C, since the Earth has not warmed up so severely that it would be 1.5 and too less to be 0.1 and 0.5.

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.
