Natural selection. darwin hypothesized that there requisites for natural selection to occur and that there are definite steps to natural selection. note the two models seen here. both of the models illustrate an important requisite for natural selection. that is: a) sexual reproduction must occur. b) there is survival of the fittest. c) variation in the population exists. d) genetic sameness reduces the chances of natural selection.

C) variation in the population exists.

Explanation:

Based on Darwin, the most important requisite for natural selection is the variance in the genetics of the individuals of some species.

These differences, produced by mutations, may have a positive effect or a negative effect in the life of the subjects, where, statistically, the positive mutations will prevail as the species reproduces.

So the right answer would be C, Variation in the population exists.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
