Explanation:
A good way to know would be by going through each one.
A) This seems the most neutral course of action.
B) There have been many studies proving the negative effects of releasing aquaculture-raised fish back into environments. There are competition issues, overpopulation issues, etc.
C) This would cause the misplacement of potentially HUNDREDS of deep-sea life forms and would only cause more pollution issues in the water to find more non-renewable resources.
D) Natural gas is a convenient and expeditious source of energy. However, it is non-renewable.
I'd say most likely A, as it supports sustainability and not a non-renewable resource or (too severe) habitat destruction
Answer:
Ribonucleotides (RNA) and deoxyribonucleotides (DNA). See more details below, please.
Explanation:
Ribonucleotides are the nucleotides of the RNA (they have pentose, ribose and nitrogenous base, except for Thymine; they contain uracil). Deoxyribonucleotides are the nucleotides of DNA (they have pentose, deoxyribose and nitrogenous base, they have Thymine).
