The correct answer is - 1,180 km.
North America and Europe move away from one another, though on the other end of the plates, the Eurasian and the North American plates are actually merging. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Then divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
Answer:
The correct answer is "Red shift"
Explanation:
Blue shift: When the source and observer approach one another, the evident frequency increments or apparent wavelength diminishes. Here the Doppler shift is positive. This is known as blue shift.
Red shift: When the source and observer move away from one another, the clear frequency diminishes or apparent wavelength increments. Here the Doppler shift is negative. This is known as red shift.
D. in the nucleus
the process of making mRNA from DNA is called transcription, it occurs in the nucleus
A - has a low diversity of genes therefore they are having issues w the breed not becoming strong but instead weaker
Initiator proteins break hydrogen bonds separating short length of DNA, AT base pairs are held together by fewer hydrogen bonds than GC pair. Thus AT pairs are easier to pull apart, At rich regions are typically found in the replication origins. Replication origins are site at which DNA is first opened.
