Basics of Eubacteria
Eubacteria is part of a different Domain, Domain Bacteria. It is the only Kingdom inside of this Domain though. It is a prokaryotic cell with a cell wall present, consisting of peptidoglycans. Eubacteria are unicellular organisms, usually in more extreme climates. Also, they can be autotrophic or heterotrophic, depending on what organism you research. Eubacteria is believed to appear 3.8 billion years ago.

E. Coli is a bacteria that can live in the body. It prefers a 37 degrees Celsius temperature, and if it isn't that temperature it adapts. It also adapts if the chemical composition isn't correct. In the position where the chemical composition isn't correct, the E. Coli will use its flagella to swim away. If the temperature isn't correct, the E. Coli will change the size of the porins found on its cell membrane.
