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.

Explanation:
Polysaccharides are long chains of carbohydrate molecules, specifically polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages.
Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers, or polysaccharides. A polysaccharide is also called a glycan.
Answer:
The founder effect
Explanation:
The founder effect is a special case of genetic drift, occurring when a small group in a population splinters off from the original population and forms a new one. The accumulation of modifications, that generally are caused by mutations, and the persistence of those changes through heredity mechanisms could make the ingredients of a new species.
Answer;
0.01 percent.
Explanation;
For individuals younger than 21, it is illegal to drive with a BAC (Blood alcohol concentration) of 0.01 and higher.
Blood alcohol concentration is determined by the quantity of alcohol consumed, body weight, food eaten, and how quickly drinks were consumed.
Driving under the influence of intoxicating beverages means that your judgement and senses are impaired by alcohol.
-It is illegal for any person to operate a vehicle with a: BAC of 0.08% or higher, if the person is 21 years old or older. BAC of 0.01% or higher, if the person is under 21 years old.
