Answer:

When AraC binds to arabinose to initiate the process of transcription, then AraC is acting as an Activator.

Explanation:

Transcription is a process that help to produce messenger RNA from the DNA that is present in the nuceloids of bacteria cells. The production of these mRNA however, depends on the intracellular condition of the bacteria, for example, if there is a need for the protein coded for by the segment or not. In the case of this bacterium, the AraC can act as a repressor only when there is no arabinose sugar in the cell. In the scenario above, AraC will act as an activator because of the presence of the sugar arabinose.

Answer:

c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.

Explanation:

Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.

In the given case, no antibiotic is needed for dental procedures.  

Based on the updated recommendations from the American Heart Association, there is no need to take a precautionary antibiotic prior to dental proceedings for the majority of people.  

It has been suggested by AHA that only those who are at greatest threat of bad consequences from infective endocarditis needs to get the short-term preventive antibiotics prior to routine dental approaches.  

It has been recommended by the AHA guidelines that various of the people who have taken preventive antibiotics in the past no longer need them, these include the individuals with the conditions, like mitral valve prolapse, ventricular septal defect, bicuspid valve disease, rheumatic heart disease, and others.
