How do the cells communicate between each other?
It is in the form of signal.
Cells exchange information by sending and receiving signals. These signals can originate from other cells or from the environment. To initiate a reaction, a signal must pass through the cell membrane. In certain situations, the signal can pass through the membrane directly; in other situations, it interacts with receptor proteins that make contact with the cell's exterior and interior. In the latter scenario, only cells with the appropriate receptors on their surfaces will react to the signal.

Through the processes of signal reception, transduction, and cellular response, cells communicate with each other through chemical signals, which are generally in the form of hormones, neurotransmitters, or direct cell-to-cell contact via specialized proteins.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
