The ability of cells to communicate, that is, receiving and sending signals from and to other cells, determines the interaction between unicellular organisms and regulates the function and development of the body of multicellular organisms. For example, bacteria communicate with each other in the quorum sensing process to determine whether they are sufficient before forming biofilms, while cells in animal embryos communicate to coordinate the process of differentiation into various cell types.

The proton is a subatomic particle found in the center of the atom.
In the physical sciences, subatomic particles are particles much smaller than atoms.

Particle physics and nuclear physics study these particles and how they interact.
The building block of proteins are amino acids. Proteins are broken down to amino acids when digesting so that new proteins can be formed.
