The data presented in Part D shows the results of artificial selection for hairy Wisconsin Fast Plants. Identify the null hypothesis for this investigation?
A. If the mean number of trichomes is greater in the second generation than in the parent population, then selection has occurred.
B. There will be no difference between the mean number of trichomes in the second generation compared to the parent population.
C. As a result of selection, the mean number of trichomes will be greater in the second generation.
D. If plants with the most trichomes in the first generation are selected as parents, then the second generation will have more trichomes.

Spirochete DNA is linear.arrow_forwardWhy can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to? A. The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them. B. The technology for extracting DNA from fossils hasn't been developed yet. C. The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading D. Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material.arrow_forwardAccording to "The Complex Evolution of Homo sapiens", what is the significance of the L3 gene and who was the L3 woman?
