Microbe CORRECT ANSWER -Free living organisms so small that they are only visible under the microscope. -Viruses are not really microbes- they lack one key quality of living cells; the capacity to main their bodily integrity throughout their life cycle. -Exceptions: Epulopiscium fishelsoni is huge (600+ um), Mycobacterium leprae is not free living. -Bacteria, Archaea, Fungi, Protists. LUCA CORRECT ANSWER -Last Universal Common Ancestor= microbe -About 4 bya -Core features for cellular...
