REVIEW QUESTIONS: (Answer when you are finished talking notes)
1. How are Eubacteria and Archaebacteria alike? How are they different?
2. Many bacteria cannot reproduce in cooler temperatures and are destroyed at high temperatures.
How do humans take advantage of this when making and storing foods? Think about what can happen to
humans that eat raw eggs or improperly stored foods.)
3. How can bacteria both cause and cure diseases?
4. Describe some of the problems humans would face if there were no bacteria.
