Which of the following elements is necessary for proper conduction of nerve impulses?
A) l B) Fe C) P D) Na
Explanation: The answer to this question is option D which is Na⁺. It is because Na and K are required for the conduction of nerve impulse.
When it comes to nerve impulse, it is an electric signal which passes along some dendrites for generating the nerve impulse.
The action potential process is a movement of the ions (Na, K) out and in of a cell.
i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
