The gas pedal opens the throttle. This supplies air to the engine and fuel is metered into the air stream to provide a combustible mixture to the engine. If the throttle is close, I.e., you lift you foot, this process stops and the engine slows to an idle setting where enough fuel is provided to keep the engine turning over but not to move the car at any significant speed. When your cruising at a steady speed, even on a flat road, the engine turns over faster and requires enough fuel so that air resistance are overcome as well as internal friction losses in the engine.
Natural selection is the answer. Natural selection is a process which organisms adapt more in their surroundings to survive longer. Therefore, when certain traits increase the likelihood of an animal living a long life, it is referred to as natural selection.

Answer:
dominant
Explanation:
In this example, if heterozygous individuals that carry one wild type allele and one mutant allele (mutant/wild-type) are phenotypically wild-type, then, the wild-type allele is dominant. This is explained by the fact that wild-type is expressed, even when mutant allele produces a non-functional gene.
