Pre-Awareness to prepare for the eruption of the volcano
Answer:
In the exceptionally cold winter of 1997, Lake Superior froze over between the Wisconsin mainland and Isle Royale. A pack of 8 wolves crossed the ice and reached Isle Royale, an island where they encountered a population of about a dozen wolves. It is estimated that the wolf population on Isle Royale has been isolated for over 100 years (~10 generations). The pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> and if the wolves interbreed with the island population, <u>genetic drift</u> will occur.
Explanation:
The founder effect occurs when a portion of a population (i-e the founders) separates from the old population to start a new population with different allele frequencies. Hence the pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> in the given scenario.
Genetic drift is defined as change in the allele frequencies in a population due to chance event. As in the given scenario, the pack of 8 wolves that crossed the ice, interbreed with the island population, thus change in the allelle frequency is occuring in the population , hence <u>genetic drift</u> will occur.

Industrialization effects the environment because people are constantly cutting down trees and not replanting a new one in its place, so this causes trees to transfer to a renewable recourses to a non renewable. One environmental issue it causes it that it makes animals have to find better places to live away from the city life and when they don't the animals end up coming into the city and disturbing the life we know now. A village in Africa actually has to share their homes and stores with monkeys because the monkeys have no where else to live so they eventually came into the city and made homes there. The environment is also being destroyed because when you pull a plant of tree out of the ground the wind starts to blow and there is nothing to hold the dirt in place any more so things like dust storms and drying out the nutrients in the ground can also occur. That was a huge cause of the Dust Bowl.
Hope I helped :)
