#11.) Phacops. It lived in the late Devonian Period (~400 million years ago).
#12.) Carbon-14 is a good radioactive isotope for determing the age of artifacts from a burial site thought to be associated with the most recent early humans because it is present in all organic matter (which humans have, of course).
#13.) 3, Devonian.
#14.) From the Devonian Period through the Triassic Period.
#15.) Cenozoic.
Their differences may eventually stop the separated squirrels from breeding with one another this is an example of an Allopatric speciation
Explanation:
In allopatric speciation, species from the same population evolve some different characters due to the differences in geographical locations.
In this scenario, the species become reproductively isolated and diverge.
The mating times of the squirrel have changed due to the environmental changes.
They no longer interbreed and hence no viable offspring thus sexually isolated from each other.
The sequence of the template DNA strand of the mRNA transcript of UGGCACUCCAG is ACCGTGAGGTC. This is from the pairing of U to A, G to C, C to G, A to T and T to U. In this case, the abbreviations refer to the nitrogen bases that are the biulding blocks of the DNA strands.
