Answer:
ATP & ADP are nucleic acids.
Explanation:
ATP and ADP are macromolecules of nucleic acids as they are made up of structures similar to DNA.
An ADP molecule is made up of two phosphate groups, a sugar backbone (ribose) and the nucleotide adenine.
An ATP molecule is made up of sugar backbone, three phosphate groups and the nucleotide adenine.
Hence, Both the structures are similar to DNA and RNA. As the structures contain nucleotides hence ATP and ADP are nucleic acids macromolecules.
Answer:
Undergrowth of water plants hypoxia
Low levels of oxygen.
Explanation:
Eutrophication occur when lake or river has adequate nutrients that will encourage the growth of water plants i.e algae which lead to the depletion of dissolved oxygen in the lake. The growth of algae is increased due to availability of carbondioxide or phosphorus or nutrients required for photosynthesis. This result in tainted drinking water,hypoxia and degradation of recreational activities.
