What is one hypothesis to explain the diversity of life (especially the honeycreepers) on the Islands? Question 5 options:

Isolation from parent population and random mutation caused the populations of honeycreepers to evolve and become different enough to be considered a new species.

Isolation and lots of predators played a major role in creating new species of honeycreepers

The islands started out extremely bare, so it was really hard for any mammals to get to the island.

All of the above

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.
