Answer:
Radiocarbon dating involves finding the age of an ancient fossil by measuring its carbon-14 content. Carbon-14 (radiocarbon), is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
Answer:
B.
Water molecules are polar.
Explanation:
<span>Take an anticodon, which is simply a three nucleotide base sequence on the tRNA. An anticodon can only carry one amino acid on it, and it has 3 nucleotides. So, take three anticodons, and how many nucleotides do you get? 9! And since an anticodon has 3 nucleotides, and since an anticodon can only have one amino acid riding on it, there must be three anticodons for three amino acids. So, then, a total of 9 nucleotides are needed.
So the answer is 9.</span>
He can assume about the number of adenines and their position on the sequence will be equal between the sample found at the crime scene and one sample from the suspicious individual.
<h3>What is forensics DNA?</h3>
Forensics DNA refers to the techniques to identify suspicious by comparing DNA profiles with those obtained from the crime scene.
Forensics DNA may result very useful to solve criminal cases by comparing nucleotide sequence between samples.
In conclusion, he can assume about the number of adenines and their will be equal between the sample found at the crime scene and the suspicious individual.

Answer:
Animals needs oxygen's to survive and plants need carbon dioxide to survive. The ozone layer reflects harmful UV rays from the sun to protect the things living on Earth.
