PRACTICE ESSAYS
1. Farmers often rotate crops on their fields. For example, one year
they will plant soybeans (a legume) in a field and the following year
they will plant corn. Why is this?
2. Describe how “super bacteria” can develop when antibiotics are
used.
3. How does a vaccine work?
4. Give 3 examples of how bacteria are useful to humans.
5. Why shouldn’t you eat a can of food that is past its use by date, even
if the can has never been opened?
