Answer:

The correct answer is "9 cycles".

Explanation:

The minimum number of cycles necessary to replicate a fragment of DNA over 500 times is 9 cycles. In Polymerase Chain Reaction (PCR) method, the fragments of DNA are doubled in each cycle. This means that after "n" cycles, the total number of fragments is given by the equation 2^n. In this case, after 9 cycles a total of 512 DNA fragments will be obtained, because 2^9 is equal to 512.

Which fossil occurs on the most landmasses? & What does this suggest about when these particular continents broke up?
Zina [86]
<span>The Glossopteridales are the fossils that occur on the most of the landmasses. They are the extinct group of seed plants. The rapid appearance of this one gives us more understanding about the Paleobiography, this is the study of animals and plants distribution through the years.
The appearance of Glossopteridales fossils also helped scientists to study so much about their species, that includes their seeds, leaves, branches and their oddly shaped roots. They grew at the beginning of the Permian and started to extinct at the end of the Permian period.</span>
