Phosphorus is an important element for all forms of life. The phosphorus cycle differs from the other major biogeochemical cycles in that it does not include a gas phase; although small amounts of phosphoric acid (H3PO4) may make their way into the atmosphere, contributing—in some cases—to acid rain. The water, carbon, nitrogen and sulfur cycles all include at least one phase in which the element is in its gaseous state. Very little phosphorus circulates in the atmosphere because at Earth’s normal temperatures and pressures, phosphorus and its various compounds are not gases. The largest reservoir of phosphorus is in sedimentary rock.
There’s an explanation. I hope this helps!
Answer:
b. they use the same set of nucleotides.
Explanation:
All the organisms use same set of nucleotides to specify an amino acid during translation because genetic code is universal. Genetic code which is a unit of genetic code is made up of various codons which are in turn a sequence of three nucleotides. Some of the examples of codons are AUG, CCG, UCG etc. Same codon specifies a particular amino acid to be incorporated into a peptide chain in all the organisms. For example, AUC specifies isoleucine in all the organisms of this earth including humans, plants, bacteria etc.
