Explain how the observations of the amoebas and bacteria studied by professor kwang jeon relate to the endosymbiotic theory.

The studies and observation made by Professor Kwang Jeon on amoebas essentially lead to the discovery of endosymbiotic theory. Wherein infection-causing x bacteria attacked amoebas, and amoebas develop a sort of resistance to x bacteria. In the initial part of the attack, amoebas were strongly affected by x bacteria, but months later, those amoebas which survived the attacked were able to produced healthy offsprings with x bacteria still thriving on their bodies. It’s interesting how amoebas develop a sort of resistance to x bacteria. But that was not just simple resistance but technically a relationship, because when antibiotics were used to kill x bacteria the amoebas also died. X bacteria have become a part of the amoeba’s system — developing a sort of endosymbiosis.
