Which of the following is the goal of the peer review process?
Masja [62]

Answer:  The ultimate goal of the peer review process is that you can have others review and look over your work for things that are incorrect, need fixing, or need rewording.  When we write things on our own, we sometimes make unconscious errors that we sometimes do not even catch in revision.  Having a new set of eyes look at something helps to catch errors that we might miss.  It is very similar to reading your work out load to catch errors, as reading something out loud is another effective strategy when reviewing your work.

Which of the following is TRUE about this reaction?
hoa [83]

The right answer is C

This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).

Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.

Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).

NO3- ==> NO2- ==> N2.
