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.
Answer:
Normalmente, la meiosis causa la división del material cromosómico, de manera que cada padre aporte 23 cromosomas a un embarazo. Esto resulta en un óvulo o un espermatozoide que solo tiene 23 cromosomas. Cuando se produce la fertilización, se origina el número total normal de 46 cromosomas en el feto. I hope it helps you
