The answer is <span>the evolutionary process through which new species emerge.
Speciation is </span><span>the evolutionary process through which new species emerge. It is the consequence of reproductive isolation of populations which then become distinct species.
Through the process of elimination:
- A</span><span>n inherited or learned trait that increases an organism’s chance of survival in its environment is an adaptation.
- A</span><span> process by which organisms that are better adapted to their environment tend to survive, reproduce, increase in number, and pass their traits on to succeeding generations is natural selection.
- A</span><span> process by which one of the extreme variations of a trait is favored is directional selection.</span>
Answer:
The correct answer is a inducer(lactose) = acts by stepping on the gas pedal.
Explanation:
In lac operon lactose act as an inducer.Lactose exerts its action by binding with the repressor and inducing a conformation al change in the repressor molecule and prevent the later from binding to the operator region.
This ultimately result in the expression of the structural genes such as Lac Z ,Lac Y and Lac A.
According to the given question if the lac operon is described using a car analogy then the inducer lactose will act by stepping on the the gas pedal and this is the positive regulation of Lac operon.
