Answer: pressurized steam

Question: Archaea are:

Answer Choices: the youngest life forms. often able to exist in extreme environments. only found in the environment, not human tissue. more closely related to the Eukarya than the Bacteria.

Answer: often able to exist in extreme environments, more closely related to the Eukarya than the Bacteria.

Question: Which group of archaea grows at very low temperatures?

Answer Choices: thermophiles psychrophiles halophiles methanogens

Answer: psychrophiles

Question: Why is it difficult to group bacteria into species?

Answer Choices: Bacterial cells can accept genetic material from other, sometimes unrelated cells. Bacteria are not alive and are not cells. Bacteria can hybridize, thus making the definition of a species difficult or impossible. Bacteria can alter their genetic makeup. Bacteria do not use a typical mode of sexual reproduction

Answer: Bacterial cells can accept genetic material from other, sometimes unrelated cells; Bacteria can alter their genetic makeup; Bacteria do not use a typical mode of sexual reproduction
