You would MOST LIKELY find a savannah grassland biome in an area with A)
50 cm of precipitation.
B)
100 cm of precipitation.
200 cm of precipitation.
D)
250 cm of precipitation.

The answer is B)  100 cm of precipitation. I had this in a test that showed a map.

Have a great day.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

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.
