Both the larger population and the isolated population were maintained under identical conditions and allowed to mate randomly for another 20 generations. few individuals become isolated from a large population and establish a new small population with a gene pool that differs from the large population. Scientists determined the frequencies of the M and N alleles in five localized and stable human populations in the Philippines (Figure 1). C. Dark color is selected for in mice from the West, Mid, and East Populations.

Even though there are numerous mountains in the region, the climate on the mountains is too cold for the lizards to survive. 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. Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms. The distance the horses ran became shorter between 1880 and 1940. The plant species will flower earlier in the spring in response to rising temperatures before the arrival of the pollinators, so seeds will not be produced. relationship between the MC1R gene and coat color in the Carrizozo, New Mexico, rock pocket mouse population? B. A shift to less polluting fuel in the twentieth led to cleaner air and a lightening of the moth's normal habitat. Assuming the thermometer to be a first-order system, find the time constant. The darker backgrounds conferred a selective advantage to the black variety, as described by natural selection. The population was predominantly black throughout the nineteenth century. A dark coat color provides camouflage to mice on the lava flow rocks; therefore, mice with dark coats have a lower predation rate in that habitat. A model of the investigation is shown in Figure 1.

Determine the amount T(C)\Delta T\left({ }^{\circ} \mathrm{C}\right)T(C) by which the two bars would need to be uniformly heated to bring the holes in the two bars into alignment. Dark coat color provides camouflage to mice on the flow; therefore, mice with dark coats predation rate in that habitat. Scientists are concerned that the lowlands will become much warmer by the end of the twenty-first century and will become unsuitable for this lowland lizard species. The current global warming trend is placing new selective pressures on the species involved in these relationships. A. Convergent evolution, because these organisms do not share a recent common ancestor. Observed modern extinction rates will resemble the rates found early in previous extinctions. The two populations will show significant genetic differences because the founder effect will result in significant losses in diversity in the smaller population. B. Start each population with genetically identical bacterial cells from a single culture to make sure that the initial genetic variation in all of the populations was exactly the same. Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a small species of primate whose D. The black variety was a nineteenth century mutation, dominant to the peppered variety. A. True The MC1RD allele is not responsible for dark coat color in the Carrizozo population, so the dark coat color is likely a result of convergent evolution. In a particular region, a species of lizard lives in the lowlands. Figure 1 shows the phylogeny of the birds. D. A mixture of ribonucleotides such as adenine and uracil will spontaneously form single-stranded chains of RNA. The original habitat had many available unoccupied ecological niches that were colonized by populations of the original species.

Which of the following best explains the mechanism that caused this speciation event in the giant kangaroo rats of population A? Formation of crude proteins occurs by chance and occurs regardless of atmospheric O2O2 levels or available free energy. The frequency of the MC1RD allele will decline due to natural selection. If sediment layers that are 3.6 billion years old are tested, they will contain relatively high iridium levels, because that is when many meteorites crashed into the Earth. C. Formation of simple proteins on primitive Earth only occurs spontaneously if the required building blocks were transported to Earth by a celestial event or a meteorite.
