Two types of organic waste produced by aquatic systems are nitrogenous compounds like ammonia and decaying organic matter.
The ecosystem found in water bodies is referred to as an aquatic ecosystem. Life exists within these waters. The two main categories of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Freshwater ecosystems can be further classified into lentic, lotic, and wetlands.[[TAG_2]]
I'm inclined to think it is C An increase in nitrogen-fixing bacteria activity, but I’m not entirely certain
To fix a thymine dimer via nucleotide excision repair, the sequence of enzyme activity is Endonuclease, DNA polymerase I, and DNA ligase. Two primary methods exist for repairing thymine dimers; one is photoreactivation, where an enzyme activated by blue light repairs the dimer, thus restoring the proper base pairing. The alternative method is excision repair, involving the uvr system that removes the dimer, with the gap filled by DNA polymerase I's proofreading capability.
