Domains and Kingdoms of Life

How many major groups are all life forms on Earth classified into?

• Three

• Two

• Four

• Five

Which domains consist of prokaryotic organisms?

• Bacteria and Archaea

• Archaea and Eukarya

• Protists and Fungi

• Bacteria and Eukarya

Where can Archaea typically be found?

• On the surface of plants

• In oxygen-rich waters

• In moderate environments

• In extreme conditions

What is the significance of archaea's ability to live in extreme conditions?

• It suggests they could exist on other planets

• It shows they are closely related to bacteria

• It indicates they are harmful to humans

• It means they are a recent evolutionary development
