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.
That would be the nucleus.
The nucleus is the control center of the cell, located in the center of a cell.
Its important not to put a person making an emergency call on hold because since it might be a patient who is a serious case and might lose consciousness. It is therefore always important to obtain the name, phone number, and location at the start of the call so that the patient can be found if they lose consciousness or is disconnected. Additionally its is important to make sure one stays connected with the patient until help arrives to ensure their safety.
The correct answer is a Bar Graph.
