Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.
Answer:
C) Both are waves of energy, but ultraviolet waves cannot be seen.
Explanation:
Both visible light and ultraviolet are two manifestations of the same thing: electromagnetic radiation (which is, basically, energy in one of its forms). They both travel empty space as waves, but visible light has a longer wavelength, which means that the distance between succesive peaks of the wave is larger than that of ultraviolet radiation. Visible light just happens to have a wavelength in the range our eyes are capable of seeing, but ultraviolet has a shorter wavelength than that, therefore we cannot see it.

It is located in the sympathetic nervous system which originates in the spinal cord. Hope this helps!
