Complete this analogy: Atoms are to molecules as tissues are to organs. You are watching a street performer do card tricks. Without looking, he is identifying the card chosen by a volunteer from the audience. When a child nearby asks, "How did you do that?" the performer replies, "By magic!" Wh...

Modern archaebacteria may tell us something about the earliest single-celled organisms because -they are the bacteria closest to the "root" of the tree of life. -they live in extreme habitats similar to the early Earth environment. -some live in deep ocean thermal vents.
