Explanation – Ions play a key role in conduction of signals from one neuron to another. Potassium, sodium and chloride ions are very important for the communication between the nerve cells. Ions helps in maintaining the potential across the membrane of the cell.
The resting potential of the membrane is due to the difference in concentration of the ions. Ion channels needs to be activated or turned on to allow in or out of the ions across the membrane.
ln most cases inorder to obtain the mass of a liquid one measures the mass of both the liquid and the container it is in and after wards remeasures the container alone and later subtract the mass of the container alone from the total mass of both the container and the liquid
