Answer: Option B) . a decrease in the amount of oxygen dissolved in

the pond

Explanation:

Anaerobic bacteria are able to survive in the absence of oxygen while aerobic bacteria survive only in the presence of abundant oxygen.

Hence, while reduced levels of dissolved oxygen in the pond decrease the amount of aerobic bacteria like Bacillus; anaerobic bacteria like Actinomyces flourish since they survive on organic substances like methane, cellulose instead.

Answer:

mRNA destroyer concentration has a greater influence because it is destroying mRNA before  proteins can even be produced.

Explanation:

<em>Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.</em>

Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.
