A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids. Codons provide the key that allows these two languages to be translated into each other.
Answer:
A. is stored after removal from the atmosphere
Explanation:
A carbon sink is a place where carbon is stored after removal from the atmosphere. Carbon is stored in a carbon sink when they are removed from the atmosphere.
A carbon sink are reservoir (usually natural) where carbon is stored. Carbon sink store carbon because of their ability to absorb more carbon. Examples of carbon sinks are plants and water. Plants and water has the capability to absorb more quantity of carbon from the atmosphere and release less quantity of carbon.
Carbon is a chemical elements represented by the symbol C. It has the atomic number 6 and belongs to group 14 of the periodic table.

C. GDP is phosphorylated to produce GTP</span>
Substrate level phosphorylation occurred in
kreb cycle inform of metabolic reaction that involve the transfer of phosphoryl
group to GDP or ADP from another phosphorylated compound which result into
formation of GTP or ATP. This process commonly occurs in the cytoplasm of cells
during glycolysis and also in the mitochondria during krebs cycle.
It was used till the 1960s. Hope i helped.
