Which prokaryote would appear in hot acidic water
Thermoacidophile
What are the two domains of prokaryotes?
Bacteria and archaea
What are some facts about bacteria
Cell walls have Pepto, no introns, loves in a wide variety of environments, lipids in the cell membrane, rRNA is unlike RNA of eukaryotes.
What are some facts about archaea
Do not have pepto, does have introns, lives in extreme environments, unusual lipids in cell membrane, rRNA resembles that of eukaryotes.
What are three primary groups of archaea?
Methanogens, Halophiles, Thermoacidophiles
