What imaginary line cuts across the top of south america?
The Equator
Answer:
B. solar day is the successive appearances of the Sun on our meridian.
Explanation:
- This is calculated by the position of the sun on the horizon and the unit of measuring solar time is a day. Thus the successive appearance of the sun on the meridian for consecutive days is thus not possible, as the 24 hours format is applied.
- As apparent from the sun being measured from the earth the solar time caused due to the motion of the actual sun, this is caused due to the two factors like the earth's orbital motion and the axial tilt.
- Further summons a constant speed, along the celestial equator and its speed are the same as the average speed of the sun.
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.
