Q

Why is the scientific method an ongoing process

A

Many times during the scientific method you will have to make changes to your experimenting, do more research, etc. After reaching conclusions, there are still more questions/tests that can be added.

Q

Homeostasis and example

How the body is able to keep a good internal environment. Negative feedback loop- body changes and works to keep the internal environment stable throughout these changes(ex-exercising- body temp)

Positive feedback loop- body notices changes and continues to cause more changes (ex- childbirth, stress)
