Do obligate anaerobes require a functional oxidase, why or why not?

Brocadia anammoxidans is required to rid of ammonia from sewer water in the treatment method, one of its main biotechnological uses. Hence, these are related to some denitrifying bacteria. What are other denitrifying bacteria that are related to this?

A chemolithoautotroph is respiring using only iron (Fe3+) and nitrite (NO2-). This bacterium does not consume organic molecules. How does this organism make ATP?

Which of the following is an example of a chemoorganoheterotroph? A.) An organism that gets its energy for ATP from the sun and its C from other organisms B.) An organism that gets its energy for ATP from organic molecules and its C from other organisms C.) An organism that gets its energy for ATP from the sun and synthesizes C-C bonds from simple molecules D.)An organism that gets its energy for ATP from inorganic molecules and synthesizes C-C bonds from simple molecules

What is the probability (in percent form) that an albino woman and albino man mate and have offspring that have normal skin coloration? b. An albino man marries a woman with normal skin color, but who had a mom that was albino. What is the probability that their first child will have normal skin color? A
