2. List the modern classification scheme. How does this differ from Linnaeus’
original scheme?

1. Compare and contrast Domains Bacteria and Archea
2. Describe the importance of Prokaryotes to other organisms.
3. Health officials worldwide are concerned by a resurgence of diseases caused by
prokaryotes that are resistant to standard antibiotics. For instance, antibioticresistant bacteria are now causing an epidemic of tuberculosis (TB), a lung
disease spread by airborne droplets. Drugs can relieve TB symptoms in a few
weeks, but it takes much longer to halt the infection, and patients are likely to
discontinue treatment while the bacteria are still present. Why can prokaryotes
quickly reinfect a patient if they are not wiped out? How might this result in the
evolution of drug-resistant pathogens?
