<u><em>Boreal forest
</em></u><em> is a large amount of carbon is being taken in by Biome</em>
Answer: C. Boreal forest
Explanation:
BOREAS is the investigation completed in the boreal woodland at Canada that spotlights on improving our comprehension of the radiant energy, heat, water, carbon dioxide and gases between the boreal forest and the environment.
An essential goal of BOREAS was to gather the information expected to improve the models of computer simulation of the significant procedures controlling these exchanges with the goal that researchers can envision the impacts of worldwide change on the biome.

DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.
Explanation:
Mutation is the process
It is caused by certain chemicals called mutagens or by environmental factors.
In mutation the nucleotide get change which eventually changes the protein product.
In mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.
A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.
In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.
