The biggest help for the scientists may be provided by the ground layer in which the bones were found. If the layer of ground is not disturbed, than the scientist can easily see the time periods from the structure and color of the ground, and thus determine the time period from when the fossil originates and the approximate age of it.

Answer: Scientists Classify Organisms into Three Domains.
Each domain is subdivided into kingdoms, followed by phyla, class, order, family, genus, and species. We will focus on domains and kingdoms. All living organisms are classified into one of three domains: Bacteria, Archaea, and Eukarya.
The cryosphere is the frozen water part of the Earth system. Beaufort Sea, north of Alaska. One part of the cryosphere is ice that is found in water. This includes frozen parts of the ocean, such as waters surrounding Antarctica and the Arctic.
Answer:
DNA strand = complementary strand
GCAAG = CGTTC
TTACG = AATGC
GATAC = CTATG
CGGAT = GCCTA
DNA strand = mRNA strand
CGATT = GCUAA
GCTTA = CGAAU
GCATC = CGUAG
TTCAT = AAGUA
Explanation: A complementary strand is not the same in base composition and sequence with the template strand. In DNA, anywhere adenine is found in the template strand, thymine is found in the complementary strand and anywhere cytosine is found in the template strand, guanine is found in the complementary strand. But in RNA, anywhere adenine occurs in the DNA template strand, uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine occurs in the mRNA strand and wherever guanine occurs in the DNA template strand, cytosine occurs in the mRNA strand.
Summarily, in DNA adenine pairs with thymine while cytosine pairs with guanine while in mRNA, adenine pairs with uracil, while cytosine pairs with guanine.
