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.

Answer:
The weather is the current condition of the atmosphere, while the climate is based on long-term patterns of the weather conditions.
Explanation:
The terms weather and climate are often confused with each other and used wrongly to replace each other. This is due to the fact that both of them describe the atmospheric conditions, but they do so in a different manner. Basically, one of them tells us about the current state of the atmosphere, and the other about the long-term patterns of it.
The weather is describing the current state of the atmosphere, while the climate describes the weather patterns over a long period of time. In order to determine the weather, we need the basic instruments used in meteorology and simple observation. When it comes to climate though, there needs to be a collection of information about the weather from decades, or even longer periods, in some cases historical data, and if we determine the climate further into the past than even geological and paleontological data.
Asthenosphere is Earth's mechanical layers that is most easily deformed.
The Asthenosphere is Earth’s mantle’s upper layer which is weak mechanically and ductilely deforming region. It is situated below the lithosphere wherein there is comparatively little resistance to the flow of plastic and the convection is thought to happen.
