Which of the following are the correct adaptations for gliding? A.)wings curved up in the back to lift bird as air flows up behind it, and front edges forcing all air downward under the
wings
B.)kiting helps birds glide forward
C.)wings curved down in back to lift bird as air pushes up and rounded front edge guiding the air up, creating a 'suction'
of lifted air
D.)wings are even on top and bottom to create the greatest possible flying surface

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.
