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..
Answer:
D: Both B and C
Explanation:
The process is never linear, scientists often answer a question that then leads to another one, therefore B is correct. C is also correct because hypotheses often change after an experiment has been done, and the goal of science is to constantly find more accurate information.
Answer:
Explanation:
They catalyze the synthesis of short RNA molecules used as primers for DNA polymerases.
Answer:
The "tail" of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water. Following the rule of "like dissolves like", the hydrophilic head of the phospholipid molecule dissolves readily in water.
Nonpolar Fatty Acids
I Hope this answers your question :)
Potassium is just below the sodium in periodic table in s group !
so the valence electron of sodium and potassium is same and that is 1 !
