Answer:

An <u>Action Potential</u> is an <u><em>"All or Nothing"</em></u> phenomenon. It was first described in 1871 by a Physiologist Henry Pickering Bowditch.

Explanation:

The action potential is always a full response, there is no such thing as a strong or weak potential. This means that when<u> a stimulus is given, a neuron either does not reach the threshold or a full action potential is fired</u>.

<u><em>STATEMENT OF LAW:</em></u>

The all or none law states that , <u>the strength of a response of a nerve cell or a muscle fiber do not depends upon the strength of a stimulus. If a stimulus is above a certain threshold, the nerve cell will send the information down the axon towards the synapse and the signal is being propagated.</u>

<u><em>SIGNIFICANCE:</em></u>

The significance of this law is that<u> it minimizes the possibility of information to be lost along the way.</u>

This law was initially applied to the muscles of heart but later it was found to be true for neuronal cells and other muscle fibers too.

Thus an action potential is all or nothing event.

BLANK VERSE - 4.It little profits that an idle king,
By this still hearth, among these

Match'd with an aged wife, I mete and dole
Unequal laws unto a savage race,
That hoard, and sleep, and feed, and
know not me.

Dear Diary,

It is interesting how life is full of surprises and we can find satisfaction and happiness in situations that we have not planned. It is even more interesting when that satisfaction and happiness is generated when we help other people. I did not imagine that relieving, even a little, the suffering of others would do so much good for my soul and my spirit leaving me so satisfied with myself.

I have always thought that I would only find happiness in actions aimed at my own satisfaction, but by helping a beggar and allowing him to have a little satisfaction in his difficult life journey, I was happy. I liked to take some of the difficulties that the beggar goes through and give him a little comfort generated comfort for me too.

I was also fully happy, excited and full when adopting a pet cat. Knowing that this animal will have a home to protect it and that it will no longer be hungry and thirsty or mistreated, fills my soul with joy.

I intend to do good deeds frequently, because I want to feel this feeling forever, in addition to contributing to the happiness of others.
