Which of the following is the best definition of biogeographic isolation? the separation of members of a species through geographical or biological forces the separation of members of different species through geographical or biological forces the separation of populations of different species through time the separation of members of a species through anatomical forces

The separation of members of a species through geographical or biological forces.

Biogeographic isolation is the separation of members of the same species which can interbred among themselves and produce viable fertile offsprings. Separation can be because of biological factors such as different seasons of mating, difference in hunting period which causes biological isolation or due to geographical barriers like oceans, lakes, rivers and mountains which causes physical isolation among members of the species.

The answer is A the separation of members of a species through geographical or biological forces, I just took the test

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.
