Answer:
The membrane potential is maintained in the cell due to the unequal distribution of the ions inside and outside of the cell. This membrane potential is important for the conduction of the nerve impulse.
The arrival of the stimulus triggers the action potential. The resting membrane potential is -70mV. This is maintained by the presence of potassium ions. The influx of the sodium ions result in the change in the membrane potential from -70mV to +30mV.
Answer: No
Explanation: Since when a child is born it has DNA from both. As an example, the mom has brown hair, father has blonde hair, the child would take the DNA for the type of hair they get, either blonde or brown. So since its blood, the fathers is A, and the boy's is B, therefore it didn't take any of their DNA's so nope, he isn't the father.
