Which graph properly depicts the relationship between the amount of gas in the swim bladder and the density of the fish?

Question

Quizplus · Accepted Answer

The swim bladder allows the fish to adjust the density of its body and thus control buoyancy. As the amount of gas in the swim bladder increases, the density of the fish decreases. This relationship is properly depicted in graph C, where the x-axis represents the amount of gas in the swim bladder and the y-axis represents the density of the fish. As the amount of gas in the swim bladder increases (moving to the right on the x-axis), the density of the fish decreases (moving down on the y-axis). The other graphs do not correctly depict this relationship.
