Large and complex cells that can be single or multicellular creatures

What are the three domains of life?

What are Archea

Prokaryotic single-celled organisms that are extremophiles

What is Eukarya

Domain that includes algae, plants, animals, and Fungi.

What are the steps for scientific method.

1) Ask a question

2) Background research

3) Write a hypothesis (must be testable and falsifiable)

4) Test hypothesis by experimentation

5) Analyze data & draw conclusion

6) Report results.
