Negative Feedback Vs. Positive Feedback- give an example of each
Negative feedback- you have a fever, your body regulates your temperature to bring it back to normal
Positive feedback- global warming leads to glaciers melting which releases CO2, which leads to more global warming...

Inductive vs. Deductive reasoning & what they are useful for.
Inductive- Specific to general
"my dog has hair, therefore all dogs have hair"
good for: forming hypothesis
