Answer:
C. Disruptive Selection
Explanation:
Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.
The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.
The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.
Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators
So you have a muscle like the biceps brachii it’s origin is connected to the humerus then inserts to the radius origin didn’t move it’s static
Answer:
Normally, transcription begins when an RNA polymerase binds to a so-called promoter sequence on the DNA molecule. ... Some regulatory proteins affect the transcription of multiple genes. This occurs because multiple copies of the regulatory protein binding sites exist within the genome of a cell.

Because at that point, the egg would already be fertilized. Now in cases like identical twins, two sperm must enter the egg at the exact same time.
