Primary pollutants affect the world more than secondary pollutants
A. The fact that it's less dense than cold air.
The sodium-potassium pump does not run out of ions since ion exchange is essential for the action potential to take place and to maintain homeostasis.
The cell has variable concentrations of different substances compared to the environment that surrounds it, with significant differences with sodium and potassium.
- The main function of the sodium-potassium pump is to maintain homeostasis of the intracellular medium, controlling the concentrations of these two ions.
- In order to carry out the adequate exchange of sodium and potassium ions in the extra and intracellular medium, the cells need an active transport process that is carried out thanks to the sodium potassium pump.
- This process is needed for the maintenance and functioning of cells, and it is essential for the action potential to be executed, necessary for the transmission of electrical impulses from neuron to neuron.
Therefore, we can conclude that the sodium potassium pump produces an exchange of potassium ions for sodium ions which keeps the cellular system functioning properly.

Answer:
The correct option of the first option
Explanation:
Dissolution of a solute in a solution is the process in which the solute interacts with the solvent leading to the disappearance of the solute to form a solution. Rate of dissolution is primarily affected by three factors namely
<u>Stirring of the solution</u>: Stirring the solution causes the solute to interact more with the solvent, <u>thus increasing the rate of dissolution</u>.
<u>Surface area of the solute</u>: The smaller the surface area of the solute, the more easier it is for it (the solute) to interact with the solvent. Hence, <u>the smaller the surface area, the faster the rate of dissolution</u>.
<u>Temperature of the solvent</u>: An increase in temperature of the solvent <u>causes the generally causes more things to dissolve in this solvent</u> due to increased energy of molecules in the solvent, which causes the molecules of the solute and solvent to interact more.
A decrease in the amount of solute<u> will reduce the amount of interaction the solute (since it is in lesser quantity) have with the solvent hence the rate of dissolution will also be low (even though a solution will still be formed)</u>.
