Answer:
Scientific: "does a sunflower or rose grow faster?"
Philosophy: "does leading by example help guide others?"
Explanation:
the first is scientific because you do experiments to find out the result as a fact.
the other one is philosophical cause it is more so an opinionated question but you can back it up still.
A bacterium has a faulty lac operon in which there is a structural defect in the operator. In this bacterium there is a structural problem with a segment of DNA that binds a repressor.
- A protein known as a repressor binds to an operator site. The operator in this instance (and numerous others) is a section of DNA that lies just downstream of the RNA polymerase binding site or overlaps with it (promoter). In other words, it lies between the operon's promoter and its genes.
- The repressor protein inhibits the synthesis of messenger RNA by attaching to the promoter region of the gene(s) (mRNA). The control of gene expression in cells requires repressor proteins.
- Thus, by physically impeding the RNA polymerase's ability to operate, these repressor proteins stop the gene from being transcribed.

I think that it is B - it is in the brain, a part of the nervous system, but it also releases hormones , which are all true.
The correct answer is D, oxygen.
