The correct answer is (d) it can eliminated from a river with minimal effort.

Zebra mussels are small mussels that live in freshwater. They are native to lakes of southern Russia and Ukraine. Accidentally, they were introduced into many other countries worldwide. They were first introduced in the great lakes. Then it started spreading throughout the united sates.They become problems  because they were not removed easily from the lakes. They started filtering water and eating the plankton. As they eat a lot of plankton, this started a competition between the zebra mussel and fishes of lake. They also clog pipes and as a result of this water cannot flow through the pipes.

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.
