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.
Answer: NATO and the Warsaw Pact were two competing alliances during COLD WAR time period.
Explanation:
Cold war was an era that started immediately after the second world war.This was to be a long lasting and continuing confrontation between the Soviet Union and the United States, lasting from 1945 to 1989. It was called the Cold War because neither the Soviet Union nor the United States officially declared war on each other.
The two major cold war alliances were the NATO (North Atlantic Treaty Organisation) and the Warsaw Pact. The countries that make up the NATO includes Britain, France, the United States, Canada, and eight other western European countries while Warsaw pact was created by Soviet Union.
For years the both alliances never engaged in military war but developed strategic policies aimed at the containment of each other in Europe while working and fighting for influence within the wider Cold War on the international stage. I hope this helps, thanks!
