Afew years after a major oil spill, which area is most fragile in terms of biodiversity? 1 benthic areas 2 polar water 3 middle water 4 open ocean

The answer is middle water. After a spill, the oil first affects the open waters where the oil first accumulates. After some years, the oil gets broken down into small particles by oil-eating bacteria and become dissolved in water. They accumulate in the middle oceans and affect biodiversity of this region.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
