Which of the following would be a result of eutrophication of nitrogen?
o
undergrowth of water plants
hypoxia, or low levels of oxygen
decreased decomposition
inactivity of fertilizers
o

Hypoxia or low levels of oxygen would be the result during the eutrophication of nitrogen.

Option (b);

EXPLANATION:

Eutrophication means a process by which lakes and streams become excessively loaded nutrient rich water.  Because of this huge number of algae or aquatic plants grow.

When Eutrophication of Nitrogen happens, growth of algae results in low levels of oxygen in water and light also doesn't reach down the water. Many animals die because of Hypoxia and as a result ecosystem is affected.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

i believe the answer would be b. hope it : )
