Answer:
Main Difference – Mutation vs Variation
Mutation and variation are two simultaneous events involved in the process of evolution. The main difference between mutation and variation is that mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species. Mutations may arise due to environmental factors such as chemicals and UV. Germline mutations are inherited by the offspring. Somatic mutations occur in the ordinary body cells. Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors. Variation may also cause evolution through natural selection.
The answer would be D) The growing population is taxing Earth’s resources which could lead to the extinction of many species (I just got this right)
Speed = frequency x wavelength
100 x 0.2 = 20
