Scientists use prior experience to…
Make predictions about what will happen under certain circumstances

Over time species change because their environment changes
Evolutioin
What is the largest level of organization?
Biosphere
What are the three parts to a feedback loop?
-Stimulus
-Sensor
-Response
Which step occurs first in the scientific method
Ask a question
A cat having kittens represents which characteristic of life?
Reproduction
What is the smallest level of organization?
Cell
Define Homeostasis
Maintaining a stable environment
A group that is used for comparison in an experiment is known as a…
The Control
Which characteristic of life are feedback loops most related to?
Homeostasis
DOUBLE JEOPARDY
List the all of the levels of organization in order from smallest to largest
Atom -> Molecule -> macromolecule -> Cell -> Tissue -> Organ -> Organ System -> Organism -> Population -> Community -> Ecosystem -> Biosphere
If someone who has diabetes has low blood sugar explain the feedback loop that is associated with this
- Low blood sugar will send a stimuli to the brain
- Since this person has diabetes they need to give themselves insulin
- The blood sugar will rise to normal
