Answer:
Competition on the same receptor binding site
Explanation:
Adenosine is a neuromodulator or chemical in nervous system that makes humans feel tired while caffeine act as adenosine antagonist of adenosine blocker that makes human feel fresh.
Adenosine and caffeine both binds to the same receptor and compete for the same binding site. When adenosine binds to its receptors, the neural activity slows down but when caffeine binds to the same receptor, it do not allow adenosine to bind the same receptor and do not slows down the neural activity.
Hence, the correct answer is "Competition on the same receptor binding site".
Answer:
One can logically and reasonably conclude that excessive dopamine could lead to schizophrenic symptoms.
Explanation:
The chemical L-dopa which is known chemically as l-3,4-dihydroxyphenylalanine or levadopa is a type of amino acid that is part of the biology of living things.
The Chemical Formula is C9H11NO4.
L-dopa is used to treat symptoms of Parkinson's disease which is caused by loss of dopamine neurons.
However, this same l-dopa is may increase schizophrenia symptoms, which could rationally mean that excessive dopamine could lead to schizophrenic symptoms.

He often prepares frozen dinners or pizza at home in the evening and routinely drinks "about 4 or 5 beers" before going to bed. Occasionally he will cook a roast and mashed potatoes. He occasionally will have milk with cereal but rarely eats vegetables or fruit. He would like to know which vitamin supplement will give him energy.1.What is Samuel’s Ideal Body Weight? What is his current percentage of ideal body weight?
Extracting the parameters from the above statements
we can calculate ideal body weight in men as
50 + (0.91 × [height in centimeters − 152.4])
convert his height in inches to centimeters
67inches=170.18
50+(0.91*(170.18-152.4)
66.1798kg
What is his current percentage of ideal body weight?
61.2/66.178*100%
92.47%
