Explanation:
Archaebacteria, meaning “old bacteria,” are grouped like that because of DNA differences and because they live in extreme environments, like salty, very hot, or very cold.
Eubacteria, meaning “true bacteria,” are grouped separately from archaebacteria because they do not exhibit those traits. Living in extreme environments is a characteristic of archaea.
Why not B: this describes archaebacteria.
Why not C: bacteria are unicellular, though they can aggregate into groups.
Why not D: they can be anaerobic or aerobic (use oxygen).
Replication is performed prior to cell division
Answer:
The original water sample contains 830,000 cells per milliliter.
Explanation:
A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.
