Would it be advantageous for the microbe to be a a) heterotroph or b) autotroph? Explain your answer

In what type of environments can a microorganism be found?

a)  bacteria are “obligate anaerobes.” What does this mean? On Earth, where might these organisms live? (Give examples.) b) Humans (and most Eukaryotic organisms) are obligate aerobes. What does this mean? On Earth, where might these organisms live? (Give examples.)

Some antibiotics show no zone of inhibition against the microbe. How is this possible? Explain how the microbe is able to combat against the antibiotic with proper reasoning.

There are major differences between the bacteria and the archaea but both groups were historically grouped together. i) summarize the similarities between the bacteria and archaea, ii) what are the differences between the two groups that allow us to distinguish them?

If the D value of a microorganism is known, what else can we find? Explain by showing the relationship between D value and your answer.
