Answer:
Contributes to the membrane potential.
Explanation:
Sodium-potassium pump: In cellular physiology, a protein which is identified in many cells that helping in to maintain the higher concentration of potassium ions inside than that is in the surrounding medium and maintain the lower concentration of sodium ions inside than that of the surrounding medium.
This unbalanced charge transfer contributes in the separation of charge across the cell membrane. Sodium-potassium pump is known for important contributor to action potential which is produce by nerve cells.
A is probably the best answer
the configuration for chlorine is [Ne] 3s2 3p5
Answer:
Option D
Explanation:
The complete question is
Which statement is true concerning colloids?
A. It carries a net electric charge
B. It consists of one phase only
C. It can be made out of two gases
D. It is electrically neutral as a whole
Solution
The particles with in the colloids are either positively or negatively charged due to presence of molecular electrolyte. The charged particles do not cluster together due to repulsion force. However, these charged particles align along two different layers - one positive layer and the other negative layer.
The net charge reduces to zero because of two forces in equal amount due to presence of equal number of positive and negative charges
Hence, option D is correct
