Domain Eukarya contains the most evolved organisms that have a nucleus and membrane-bound organelles. Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Halophiles (saline) Thermoacidophiles (hot spring), Methanogens (gut of ruminants) b) Eubacteria - True bacteria - Rigid cell wall - Motile flagellum. must be adapted to high salt levels, whereas in the compatible solute adaptation, little or no adjustment is required to intracellular macromolecules; in fact, the compatible solutes often act as more general stress protectants, as well as just osmoprotectants.[3]. An organism that thrives in an environment of high salinity Some bacteria can be beneficial or helpful because they can be used to produce antibiotics. -the more species an organism has, the more likely it is to be able to recover from a natural disaster, such as a drought. These organisms produce colored pigments with antioxidant properties. Halophiles can be found mostly in the domain Archaea, which contains single-celled ancient prokaryotic microorganisms.
