The flu is caused by

Bacteria can be helpful to humans by 

• producing vitamin K
• helping to digest food
• protect against harmful bacteria
• all of the answer choices.

If you go to a doctor and are prescribed antibiotics you probably have an illness cause by a

• "against growth"

• "against disease"

• "against all odds"

• “against life”

Broad spectrum antibiotics are good because:

• They Kill many different pathogenic bacteria

• They are really cheap to buy

• They cause antibiotic resistance

• None of the above

Broad spectrum antibiotics are bad because:

• They kill many different pathogenic bacteria

• They are really cheap to buy

• They can increase the rate of development of antibiotic resistance

• All of the above

The following organisms can be killed by antibiotics

• Fungi

• Protists
