Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
A halite crystal belongs to the cubic crystal system. The other five crystal systems are monoclinic, triclinic, orthorhombic, tetragonal, and <span>hexagonal.
The cubic crystal system is characterised by</span> <span>the way the atoms in the mineral are arranged in the three </span><span>dimensional</span><span> shape of a </span>cube. The halite crystal has this shape. Attached is an image of it.

Answer: C) Perform the jaw-thrust airway maneuver.
Explanation:
The patient is suffering from breathing problem and her airways must be opened to allow breathing.
The jaw-thrust airway maneuver must be performed on elderly women. This is because of the fact that it is an ideal technique for patients who are suspected of having head or neck injury. This is done for patients who are unable to maintain their own airway during injury. The jaw-thrust maneuver is done by placing the index finger to lower jaw upwards and thumb is pulled down on the chin to open the mouth this will help to open the airway.
