Caffeine works as an adenosine receptor antagonists, this essentially means that it works in the opposite manner or works against the receptor. Think of antagonist in the term of literature it goes against the agonist. Adenosine when bond to the receptor causes tiredness, this is the reason why people drink caffeine to stay wake and to prevent cognitive decline from exhaustion. So caffeine doesn’t really effect learning or memory to a large extent like other stimulants do. So basically caffeine increases wakefulness which in turn allows a person to focus longer, slight increase in memory, and more of a sorted out thought process.
Answer:
to carry heavy load on the vehicle's outside
Explanation:
Aerodyanmic properties of a car refer to its interactions with moving air and the properties which govern smooth movement of the car through air. Aerodynamics of a car address the concerns like lowering noise emission, prevention of heavy load and avoiding the luggage dragging.
Now when there will be great load outside the car,the air will resist the movement of car more, so it will be difficult for the car to cut through the air. Moreover, when a car carries huge amount of load outside its body, the frictional force by aerodynamic drag increases greatly. This can badly effect the performance of high speed cars like sports cars but for other normal cars it poses less hazards.
Hope it helps!

I believe the triceps brachii is acting as an agonist. The triceps is an extensor muscle of the elbow joint and antagonist of the biceps and brachialis muscles. It can also fixate the elbow joint when the fore arm and hand are used for the fine movements. For example during elbow extension the triceps Brachii acts as the Agonists while the Biceps Brachii acts as the Antagonist.
