Which of the following is not a mechanism to prevent oxygen from entering the environment of nitrogenase? group of answer choices reduction of iron to prevent oxidation protective proteins sequestering the nitrogenase using specialized cells to sequester nitrogenase separating oxygenic photosynthesis and nitrogen fixation temporally

Reduction of iron to prevent oxidation.

Explanation:

Bacteria has several mechanisms to protect the enzyme nitrogenase, one of them involves the increase of their metabolism to reduce the oxygen availability.  

Besides this mechanism, there is also a conformational protection. This involves an interaction with FeSII protein, a ferredoxin. This protein is found as a homodimer that contains a 2[Fe-S] cluster, so reduction of Fe is not one of the mechanisms.  

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

the answer is 1. photosynthesis. glad to
