Cells with mitochondria were able to utilize metabolic energy more efficiently. One group is given food with an added substance that is known to be a mutagen. The increased air pollution of the nineteenth century due to the use of coal led to a darkening of surfaces from soot. Hunting in the nineteenth century has been blamed for a drastic reduction in the northern elephant seal population. The same species will be found in both static periods, but they will have different shell shapes. Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a small species of primate whose Image courtesy of Pixabay Facts about the test: The AP Biology exam has 60 multiple choice questions and you will be given 1 hour D.

Dr. Sidney Fox wished to add to the heterotroph hypothesis of the origin of life by synthesizing simple proteins from a mixture of amino acids. Some lizards will migrate to new habitats in the mountains and become isolated, leading to allopatric speciation.

The species will experience a genetic bottleneck, and sympatric speciation will result in the development of several new species. Natural selection acted on variation that was present in both populations A and B, and the lack of gene flow eventually led to the formation of two new species. A shift to less polluting fuel in the twentieth led to cleaner air and a lightening of the moth's normal habitat.
