Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.

The 13th amendment banded slavery.
Answer:
As democracy means rule of people ... That is of the people for the people and by the people. Democracy is a form of government in which all eligible citizens participate equally—either directly or through elected representatives. Democracy is the best form of government simply because no other form of government is known to work well. Democracy may have its flaws but all in all it works very fluidly. Some plus points of having a democratic form of government:-
1. Freedom
2. Democracy represents the views and notions of all the citizens of the country, whether majorities or minorities.
3. It helps in solving conflicts and quarrels in a better way.
4. It provides a dignity to the people.
5. Democracy allows various people to rule the country through the representatives.
6. It also allows people to express themselves clearly and freely.
7. It Respects & promotes Human Rights
8. In this form of government all people are equal before the law.
9. Democracy is the only form of government where the people can voice their opinion.
10. In my view there is no other alternative form of government better than a democracy.
