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:
(a) The central nervous system is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric animals. It consists of a large nerve running from the anterior to the posterior, with the anterior end is enlarged into the brain.
(b) The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.

⊂ Valhalla is a place where the gods don't just drink and revel but also train and fight. The Wrath of Odin workout is for those ready to prepare for that kind of 'revel' by punishing their body. Good for the soul and probably the closest you get to feeling like a Norse god. ⊃

Microwave before cooking
details :
Steam frozen vegetables by pouring them into a microwave-safe glass dish and adding just a few tablespoons of water. Microwave the veggies in 90-second intervals, stirring and checking for desired doneness after each interval. If you prefer soft and tender veggies, they'll probably need a few minutes in the microwave
Uhm to be honest..
All types of exercise ask for oxygen to produce energy... so this is a bit confusing but it would be easier with answer choices:/
