<span>I believe that the pattern that would be expected is both 14 N and 15 N, this is because the DNA was replicated in a conservative manner. Semi conservative replication would produce two copies that each contained one of the original strands and one new strand, while Conservative replication would leave the two original template DNA strands together in a double helix and would produce a copy composed of two new strands containing all of the new DNA base pairs</span>
Well, historical events is a broad subject, but there are specific events that could contribute to how we value and think about the environment. for example, events as broad as wars or as specific as the gulf of mexico oil spill contributes to the way we treat our environment. and, as a society, we know about global warming and pollution, and if we analyze mistakes we made in our past through events, it could be possible that it benefits our relationship and care for the environment in the future.

Answer: a. dead organisms from the marine food web.
c. liberation through ATP hydrolysis in living organisms.
Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling. In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.
