Nitrogen is released to the abiotic parts of the biosphere from the process death and by bacteria.
It took BP 87 days to stop the flow of oil they monitor it for 48 hours to make sure it was going to hold
Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms.
