Answer:
The Sun *emits* white light, which is actually a composite of all of the visible frequencies of light. (A prism shows you the visible frequencies of white light.) The distribution of solar frequencies is uneven, the most intense frequency is in the yellow-green part of the spectrum.
Answer:
Both natural selection and genetic drift are mechanisms for evolution (they both change allele frequencies over time). The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.
