Active transport is a process requiring energy in which a substance crosses the cell membrane. When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.<span>

<h3>What are Solids?</h3>
Solid is a state of matter which is characterized by the particles present
being tightly held together. Solids have a higher heat retention capacity
as a result of the particles being very close to another.
This is the reason why solids are used as conductors of heat and
electricity for different purposes.
