he chemical moiety of nucleotides that allows quantification of concentration via UV absorbance is the:

give brainliest

water pollution kills aquatic life. aquatic life includes algae and other plant life that use photosynthesis. photosynthesis takes   c02 out of the air.  

c02is a greenhouse gas.

oxygen, selenium, tellurium, and polonium.
