Explanation:
The correct answer is option A.
Carbon-14 is a dating technique used to estimate the age of the bone which is less than 40,000 years old.
When an organism dies the carbon 14 is converted into nitrogen 14 so, we can estimate the age of the bone.
This method is used by the archaeologist to find the age of the dead and decay animals present inside the earth's surface to study the earth and creature who have lived on earth.

Answer:
fertilizer creating a mutation among a farmer's crops
Explanation:
A genetic factor is one that affects the gene or genome of an individual organism. This genetic factor often influences the observable trait called PHENOTYPE of the organism. In this case, an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor is the "fertilizer creating a mutation among a farmer's crops"
The fertilizer represents the environmental/chemical factor which is creating the genetic factor (mutation) that will eventually influence the growth or development of the crops.
The outer ring is is the ever first ring but the inner ones tell if it’s old or not.
1) RNA polymerase finds the promoter sequence on DNA.
2)RNA polymerase reads the DNA and builds complementary sequence.
3) Intron séquences are spliced out and exons are joined together.
4) The ends of the mature transcript are protected before it leaves the nucleus.
5) The mRNA attachés to the ribosome.
6) transfer RNA arrives at the ribosome and the anticodon complements to the mRNA codon.
7)amino acids form peptide bonds as tRNA molecules match the mRNA.
