There appears to be some relationship between population density and the presence of large dead zones. Can you explain why dead zones seem to be more prominent in areas of high
population density
Nitrogen and phosphorus runoff from sewage and agricultural activities in high population centers leads to the formation of dead zones.
People in these high population areas have over fished their coastal waters, leading
dead zones
The abundance of cruise ships in these high population centers results in the production of large amounts of pollution, leading to the formation of dead zones.
This is a random correlation and not a result of population centers causing the dead zones

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
