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.
