Animals that only survived in certain climates have fossils that are in the opposite of the range of temperatures needed for their survival. Also The plants have fossils in two different climate regions that indicates that the region was once in a different location. Such as the fossil of a plant called glossopteris. And deep scratches in rock found in South Africa that are usually created by the movement of glaciers.
No I think you need to do some more research
Answer:
E) No action potential would be generated.
Explanation:
As we know the voltage gated Na and K channels has specific roles in the generation of action potential. When both the channels are opened at the same time sodium will move inside and potassium will move outside no action potential would be generated.
At the peak of action potential , area of the neuron is about 40 mV positive. Now when the voltage becomes positive , sodium channels close and the potassium channels open.
When the potassium channels open , they cause the potassium ions to rush out of the cell thus causing the voltage to become negative again.
Hence E) No action potential would be generated is the right answer.
