Answer: A
Explanation: PCR help to create multiples of copies, it can produce millions of copies of DNA sequence in a test type in limited or few hours. PCR has revolutionize molecular biology, and it has become an essential tools for biologist, physicians or anyone who really want to work on the DNA.
The mass of one atom of carbon in the correct number of significant figures is 1.99×10-²³. There are four significant figures each in both the atomic mass of carbon (12.01 g) and Avogadro's number, so the answer must also have 4 significant figures. The operation is shown below:
<span>12.01 / (6.022x10²³) = 1.994x10</span>₋²³<u />
Mitosis produces identical cells
Meiosis produces cells that are different from the original cell
If think about it if it was asexual then it came from 1 parent so it would be W
The correct answer is - underwater mountain ranges.
The mid-ocean ridges are actually underwater mountain ranges, which usually are very long, in fact the longest mountain range on Earth is created on the divergent boundary between the Eurasian and North American tectonic plates and between the African and South American tectonic plates. At the divergent tectonic boundaries we have the creation of new crust which rises from the mantle and fills in the gap between the tectonic plates. Because of the big amount of magma and high pressure, very big and long underwater mountain ranges are formed.
