Answer:
1. Number of DNA molecules after 30 Cycles of PCR = 1.02 x 10^9
2. No. of mutant DNA molecules = 1.07 x 10^9
Explanation:
1. You just have to take the exponential of 2 to the power of the number of PCR cycles (2^n)
2. All copies were normal at cycle 10 that are about 1024 copies. At cycle 11 single point error, all further copies are mutated.

Explanation:
<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>
When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.
<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.
