17. Male mussels release sperm into the water. Female mussels take the sperm into their gill chambers where fertilization occurs. Young mussellarvae are released into the water where they float freely until they attachto the gill of a host fish. After the juvenile drops off the fish gill, it burrows into the river bed and begins the life cycle all over again. The parasitic behavior of the larvae benefits the mussel in two ways. Onebenefit is that the fish provides nutrition for the larvae when they are attached to its gill.What is the second way this behavior enhances the survival of the musselspecies? A. The large size of the fish provides the mussel larvae with plenty of

room to grow.B. The parasitism increases the opportunity for the mussels to mate with

other mussel species.C. The mobility of the fish spreads the mussels to areas they would

otherwise be unable to reach.D. The location of the larvae on the gills of fish reduces the exposure of

the larvae to oxygen-rich water.

C. The mobility of the fish spreads the mussels to areas they would otherwise be unable to reach.
