Definitions:

Protons

Protons are positively charged subatomic particles found in the nucleus of an atom, contributing to the atom's mass and defining the element's identity.

Synergistic Interaction

A situation where two or more substances or organisms work together to produce a combined effect greater than the sum of their separate effects.

Homeostatic Interaction

The process by which biological systems maintain stability and equilibrium within their internal environment despite external changes.

Positive Feedback

A process in which the output or result of an action enhances or amplifies the original action.
