People have cut down forests to clear land for crops, cattle, roads, and cities. These trees are also used for fuel, building ma

terial, and paper. The loss of forests have had the following effects (choose all that apply):
A. Causes many species to lose their habitats and food sources, resulting in many becoming extinct or endangered.

B. Creates erosion. The roots of plants hold soil in place to prevent erosion and absorb rainwater, preventing flooding.

C. Creates pollution with the use of DDT, which is a fertilizer that impacts the health of many organisms in the area.

D. Contributes to global warming. The abundant plant life in forests takes in carbon dioxide and stores the carbon as a source of energy. Without forests, the carbon that would have been stored in the trees exists as carbon dioxide and contributes to global warming.

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included bot
vlada-n [284]

Answer:

1)

  • frequencies of light-colored mice  ≅ 0.74
  • frequencies of dark-colored mice ≅ 0.26

2)

  • frequencies of light-colored mice ≅ 0.13
  • frequencies of dark-colored mice ≅ 0.87

3)

  • q² = 0.74
  • p² = 0.02
  • 2pq = 0.24      

4)

  • q² = 0.13
  • p² = 0.4
  • 2pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.
