Answer:
Gated ion-channels
Explanation:
These ion channels are protein molecules that act as a passageway which span across the cell membrane allowing the movement of ions from one side of the membrane to the other. They possess the ability to open and close in response to either chemical or mechanical signals.They possess a fluidic pore, which becomes available to ions after a conformational change in the protein structure has been activated causing the ion channel to open. Based on the stimulus to which they respond, ion channels are divided into three groups: voltage-gated, ligand-gated and mechano-sensitive ion channels. Channels responding to electrical (voltage-dependent ion channels), mechanical, or chemical (ligand-gated ion channels) stimuli open and allow rapid ion movement into or out of the cell, and this movement creates an electrical signals.

Answer:
Demand for avocados would increase, causing prices to increase.
Explanation:
If avocados are proven to lower the risk of diseases, more people would want to buy them, meaning demand would increase.
When demand increases, people would be willing to pay more for that item, meaning price would increase.
Therefore, the answer is the second option: demand for avocados would increase, causing prices to increase.
The answer would be beta blocker.
Beta blocker is an antihypertensive drug that works by <span>decreasing norepinephrine release. The reduce of norepinephrine would prevent vasoconstriction and increased heart rate. This two effect contribute to the orthostatic hypotension the patient describe.
Some of the drugs are lipophilic which means it can pass blood </span>brain barrier, cause some effect like vivid dreaming. That is why the drug best to take on morning, not evening.
