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.

Vesna [10]
<span>“How horrible it would be . . . if she were condemned to be the plain, shy Millicent of a few years back.” - Direct characterization. The speaker explicitly says that Milicent now isn't plain and shy, and that would be a condemnation to her.

</span><span>“Betsy Johnson, the vivacious blonde secretary of the sorority” - Direct characterization. We can see Betsy and we get some information about her character (vivacious).

</span><span>“Walking beside Louise on the way to the drugstore, Millicent felt a surge of pride.” - Indirect characterization. The speaker doesn't say that Milicent is this or that kind of person. He/she just puts her in a context, commenting on her current feelings and thus allowing the reader to make a vague conclusion about her character.

</span><span>“Bev was suddenly there in the doorway. ‘Wipe that smile off your face,’ she commanded.” - Indirect characterization. Again, the speaker here describes this character's action, rather than features and character traits.</span>

A phone call startles me out of a deep sleep. I sit up straight in bed, my heart pounding. "Hello?" "Hello, Kevin." I know his v
zaharov [31]

Answer and explanation:

The interior story, as the name suggests, is the story within another story. In this passage, the frame story is the speaker, Kevin, receiving a phone call from Matt, a friend he hasn't seen in almost ten years. The frame story is the one that involves the interior story. The interior story begins with the line '"Kevin, come inside!" my mother called.' This line separates the current moment from the moment the speaker is remembering - he and Matt playing outside; Kevin's mother calling him in. There is another story being told now, one about the past. But it is told as if it were happening at this moment. We have, from this moment on, an interior story.
