The study of life
List and describe the characteristics of life
Cell
Order

Response to environment
Regulation
Energy processing
Growth and development
Describe the different levels of biology
Molecules
Organelles
Cell
Tissues
,Organs and organ systems
Organisms
Population
Communities
Ecosystems
The biosphere
Describe how energy flows through an ecosystem
Starts from sunlight, then each level of the ecosystem gets energy from its food source
What characteristics do eukaryotic and prokaryotic cells have in common? How do they differ?
Same: Both are cells
Differ:
-Eukaryotic: nucleus
-Prokaryotic: does not have nucleus
What types of organisms are prokaryotic? What types are eukaryotic?
Eukaryotic: Animal and plant cells
Prokaryotic: Bacterial and archaea

Describe the role that DNA plays in the growth, development, and reproduction.
DNA creates everything in an organism
What is positive feedback?
Feedback that increases the output of a process.
What is negative feedback?
A response to a change in the body that counteracts or opposes the initial change.
Describe the steps of the scientific method
1) Hypothesis 2) Design an experiment 3) Conduct experiment 4) Collect Data 5) Compare results/
Research 6) Re-test to conclude if data is significant
What does it mean that a hypothesis must be testable and falsifiable?
Able to be tested and the ability to be wrong
Describe how reproductive success influences evolution. Describe how the environment can affect
reproductive success.
Reproductive success=living organisms=offspring (successful genes to offspring)
