Answer:
A drug that blocks the effects of a neurotransmitter is known as antagonists. A drug that mimics or increase the effects is known as agonists.
Explanation:
An agonist is a chemical that binds to a receptor and activates the receptor to produce a biological response. Whereas an agonist causes an action, an antagonist blocks the action of the agonist. A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. They are sometimes called blockers; examples include alpha blockers, beta blockers, and calcium channel blockers..
A) Amsterdam is the answer
5 is b because it makes more sense
The light-independent reaction for obtaining energy (I think this is what you are talking about) occurs within the organism. This is because cellular respiration does not require light, seeing as how most humans do not need light directly (although they need the Sun for photosynthesis to occur in plants so that the plants produce Oxygen) in order to survive. Hopefully this helps!
