Explain how microbes have helped the earth’s atmosphere. ? Explain.

They created much of the earth’s oxygen, and they continue to create about 50% of the oxygen.

 Are viruses living organisms? Explain.  List five ways

microbes

are helpful to humans.  How do

viruses

infect cells and multiply?  Why are

viruses

considered non-living?  How does a

vaccination

work?  How did Edward Jenner discover the process of vaccination? (Look at the timeline of Fighting Infectious Disease on p. 606)  How did Alexander Fleming discover antibiotics? 3

 List three ways

disease

might be avoided.  Why can bacteria become

resistant

to antibiotics over time?  How would bacterial reproduction from conjugation help a colony of bacteria to become resistant to antibiotics more than if the bacteria reproduce by binary fission?  What were the bubbles in the root beer, and how did the yeast create them?  Explain how two or more of the human body’s systems work together to keep out or kill harmful pathogens.  Explain why the line on your Bacterial Growth Graph keeps getting steeper and steeper.  Look at the timeline of Fighting Infectious Disease on p. 606. What do you think are the two most important discoveries? Why?  Explain the results of your Fomite Lab investigation. Where did you swab?
