In what ways are prokaryotes key to the survival of many species?
In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common?
Question options:
They both have identical cell walls.
They both have prokaryotic cells.
They both thrive in extreme environments.
They both are able to live only under anaerobic conditions.
In what ways are the prokaryotes metabolically diverse? How is this diversity helpful with respect to nutrient cycling? Useful in bioremediation?
