What are characteristics of archaebacteria?
Archaebacteria are unicellular prokaryotes that are the oldest living organisms on Earth. Some characteristics include survival in oxygen-free environments, being extremophiles and reproduction is asexual.
What are two organisms in the Archaebacteria kingdom?
The members of the kingdom Archaebacteria possess bacteria and eukaryote. They are single-celled organisms, prokaryotes, the same size and shape as bacteria, and possess genes and metabolic pathways.
Mushrooms algae and protozoa are all examples of?
Bacteria are of the kingdom Prokaryotes Blue-green Algae have now been discovered to actually be prokaryotes, so they have been renamed as Cyanobacteria, of the Prokayote kingdom. Actually they are in the Monera kingdom but nowadays it is in the Blue green algae is in the Archaebacteria Kingdom and bacteria is in the kingdom Eubacteria.
If scientists found a new planet outside our solar system that had an atmosphere similar to Earth's three billion years ago what kingdom's organisms would you expect the new planet's organisms to re?
Archaebacteria
What is the primary evolutionary unit in living organisms?
population is the primary evolutionary unit of any living organisms
What group or organisms makes up prokaryotes?
Bacteria and archaebacteria both make up prokaryotes.
Which 2 kingdoms contain all the prokaryotic organisms?
"There are two kingdoms of prokaryotes. These are the bacteria (or eubacteria) and the archaebacteria (or the Archaea)."
How do scientist infer evolutionary relationships among organisms?
scientists can infer how closely related the organisms are in an evolutionary sense

What kinds of organisms live in Earth's most extreme environments and may provide scientists with clues about possible life forms on other planets?
organisms in the archaea kingdom Prokaryotes
Scientists determine evolutionary relationships by looking at breeding behavior geological distribution and structural similarities between organisms true or false?
It is true that scientists determine evolutionary relationships by looking at breeding behavior, geological distribution, and structural similarities between organisms. Scientists can use other criteria to determine evolutionary relationships.
How do scientists use scientists use structural similarities to determine the evolutionary relationship?
They see similarities with structures between modern day organisms and older organisms.
What are some characteristics of archaebacteria?
Archaebacteria are the oldest organisms living on earth. They are unicellular prokaryotes and belong to the kingdom Archaea. They can be found in very harsh conditions such as volcanic vents or the tundra.
