Answer: This is known as RISK ASSESSMENT.
Risk assessment can be defined as the determination of the potential impact of an individual risk by measuring or otherwise assessing both the likelihood that it will occur and the impact if it should occur, and then combining the result according to an agreed rule to give a single measure of potential impact.
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.
