Golgi complex

Explanation:

The Golgi complex, also known as the Golgi apparatus, is a cell organelle of eukaryotic cells that functions to sort different molecules which are destined to the plasma membrane. In the Golgi apparatus, proteins and lipids from the Endoplasmic Reticulum (ER) are subsequently processed and classified to be transported to different cell locations including, among others, the plasma membrane, or vesicles which are secreted from cells by exocytosis. Moreover, this organelle also contains specific enzymes (glycosylation enzymes) that function to modify proteins in order to form glycoproteins.

Oliga [24]

ANSWER: IT'S CALLED THE ZEROTH LAW OF THERMODYNAMICS

EXPLANATION:

The zeroth law of thermodynamics state that there's no heat transferred between two objects in thermal equilibrium (i.e having the same temperature). This phenomenon depicts that there's balance in the amount of temperature in all the three entities.

This phenomenon was credited to Sir Ralph Howard Fowler, a British physicist and astronomer during his lifetime.

A scientific paper by Carathéodory also added that when two systems S1 and S2 are made to reach equilibrium with a third system S3 under close thermal conditions, systems S1 and S2 are said to be in mutual equilibrium.
