Answer:
The answer to the question: The movement of ions through their channels require a discharge of the capacitance, is, true.
Explanation:
In order for cells, muscular and neuronal, to perform their activities, they need to generate action potentials, that will permit these activities. In order for an action potential to happen, a cell´s membrance must be charged, or rather, its polarity must be changed, so that the cell can be charged and then fire. Usually, cells remain in a resting membrane state, in which, the extracellular matrix remains positive, while the intracellular space remains positive, due to ion, and anion presence in either. In order for the action potential to happen, these polarities are reversed through a series of steps in which ions, particularly potassium and sodium, sometimes calcium, will enter and exit the cell´s membrane to change this polarity. But in order for this process to take place, first a current, or stimulation, must motivate the cell to start the process. The capacitance is the capability of a cell to be ready to be activated or de-activated when stimulated, meaning, to be charged and discharged, when necessary. In order for this capacitance to permit the process of action potential formation, it needs to be discharged first, and this is done through the stimulus, which orders the cell´s membrane to initiate depolarization by opening up the ion channels. This is why the answer is true.

Answer:
In my opinion, if you feel that using a double mask will make you feel safer, then you should use it, but using a mask is important. Now, if you are already fully vaccinated I don't think you should use a mask unless you want to, which is totally fine.
Explanation:
Answer:
- First, place some gauze pads or a clean cloth on the wound and hold for 10 minutes.
- If the gauze or cloth becomes soaked with blood, without removing it, place another on top and continue pressing for another 10 minutes.
- If the blood does not stop flowing, place the wound raised upwards to avoid excessive bleeding.
While you call an Emergency Ambulance.
Explanation:
Bleeding usually occurs from a cut or trauma that causes the blood vessels to break.
An arterial hemorrhage occurs when the outflow of blood comes from the circulatory system to the outside caused by the rupture of an artery.
Until the artery closes or the wound is cauterized, blood is likely to continue to flow until the person shows symptoms of confusion, slow heart rate, and shock that ultimately leaves the person to bleed to death.
