Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
<span>The correct option is: IT HELPS CARRY AN IMPULSE BACK TO THE NEXT NEURON. There are two types of neurons, excitatory and inhibitoty neurons. Both serve to transmit impulse from one point to the other. Each neuron usually makes several connections with other cells.</span><span />
The advantage of the epidermis being clear is that the light can pass by easily without a problem. If we could not let the light pass we would have no pigmentation and that means we would have no skin tone. We would all just be really white and out pigmentation would not be there.
