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.
Batter A will likely hit the ball at a greater distance than the other in this scenario.
<h3>What is Distance?</h3>
This is defined as the numerical measurement of how far apart objects or points are.
Batter A will likely hit the ball at a greater distance because it is directly proportional to the velocity which will make it go farther as swinging the bat from a resting position on his shoulder exerts more force.
