Answer:
Adenosine.
Explanation:
Adenosine is a neurotransmitter that is created in the brain and when it binds to the adenosine receptors, it slows down nerve activity and it creates a sensation of drowsiness.
<u>Caffeine</u> looks like adenosine to the receptors, therefore, when we have caffeine, <u>it binds to these receptors and there is no room left for the adenosine to bind</u>. However, the caffeine doesn't slow down nerve activity but, in the contrary, it speeds it up.
Therefore we can tell that caffeine blocks the receptors for the adenosine thus promoting wakefulness.
I think illusion or distraction
Answer:
Lewis’ complex tone in which he is about his topic or position, moving between straightforward analysis and raw emotion, is called the objective or formal tone.
Explanation:
This tone is characterized by the means that the text will be referred to us in an impersonal style of writing, in a precise language which will give us rarely ambivalent information, but won´t include information about how the writer feels and won´t share writer´s opinion.
It requires a writer to do a vast amount of research to help support his ideas, to write in an official-sounding manner stating opposite viewpoints using facts and data only. It also requires adherence to some rules of language like refraining from using personal pronouns as it might indicate personal feeling and emotive words that might indicate an opinion on the part of the writer, avoid contractions and use passive voice.
The word choice in this tone needs to be considered carefully using words that are precise, objective, appropriate and impersonal, avoiding judgemental words and slangs, as it is used when a writer wants to deliver information in a neutral, factual and unbiased way so void asking questions too.
