Answer:
Na+ ions diffusing across the membrane through leakage channels the generation of local currents
Explanation:
An action potential occurs when the membrane potential of a specific cell location rapidly rises and falls. There is a voltage difference between the exterior and interior of the cell, called the membrane potential, due the Na+/K+ ATPase pump.
Starting from the resting potential, the action potential starts when the thershold is reached when Na+ ions difusse across the membrane through channels.Then, the interior of the cell becomes positive and the exterior negative.
The K+ channels take place when the repolarization phase stars, letting K+ ions difusse from the inside of the cells to the exterior.
Answer:
Option b=> 0.1 M CH3COOH , 0.1 M CH3COONa.
Explanation:
In chemistry, when an acid or a base(alkali) is added to a solution and the solution pH does not change then we say that the solution is a BUFFER SOLUTION (that is a solution, upon the addition of acid or base will show resistance in pH value).
In order to be able to answer this question efficiently we have to consider the mathematical representation or Equation below;
pH = pKa + log ( [ A^-] / [HA] )--------------------------------------------------------------------(1).
What the mathematical representation or Equation (1) above is telling is is that if [A^-] or [HA] is high then there will be the production of buffer with higher buffer capacity.
Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become. Hope this helps please mark brainliest :)
The answer is A. The pH decreases
Answer:
Yes it is
Explanation: because it is composed of identical molecules consisting of atoms of two or more chemical elements.
