Q4. What is the best evidence against the idea that organisms will evolve because they need to survive in a changing environment?

Q5. Which is more likely to lead to speciation, disruptive or balancing selection, and WHY?

the answer would be 3

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.
