Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
There are choices for this question namely:
<span>right primary
right secondary
left secondary
left primary
</span>
The correct answer is "right primary" or the right main bronchus. Anatomically, the right main bronchus has a larger diameter and a steeper angle (to compensate for the location of the liver). When a foreign body is accidentally aspirated, most commonly, it will lodge on the right main bronchus; especially in children.

Answer:
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
