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:
5.05 lbs
Explanation:
2/9.81 m/s^2 * 24.79 m/s^2
9.81 m/s^2 = Force of gravity on Earth
24.79 m/s^2 = Force of gravity on Jupiter
The correct answers are:
1. II and IV;
The relic boundaries are man-made boundaries that have existed in the past, but they are not existent in the present. This type of boundaries are often reminder of a period of dividing between the people with force. In the present, the relic boundaries may be found useful in order to divide the country into voting districts, but it can also very often be seen that even though the boundary doesn't exist anymore, the people on the opposite sides of it have different cultural traits. The perfect example is the Berlin Wall, where even nowadays it can easily be noticed that there's cultural differences between the Germans from the Western and the Eastern part.
2. II and IV;
The federal style of government is functioning very well in multiple countries throughout the world, but it also may be a step towards independence of a certain territory.
However, this system functions the best if a country has multiple ethnic groups, which dominate certain part of the country, or if the country has multiple political exclaves. A nice example is the Russian Federation, where these are the exact concepts used for the federal units in the country like Chechnya, Tuva, or Tatarstan.
Answer:
The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite. ... The Earth has an outer core (liquid) and an inner core (solid).
Explanation:
The flow of heat from Earth's interior to the surface is estimated at 47 terawatts<span>(TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of </span>isotopes<span> in the mantle and </span>crust<span>, and the primordial heat left over from the formation of the Earth.</span>
