Part A
Fish can adjust their buoyancy with an organ called the swim bladder.
The swim bladder is a flexible gas-filled sac; the fish can increase or
decrease the amount of gas in the swim bladder so that it stays
neutrally buoyant-neither sinking nor floating. Suppose the fish is
neutrally buoyant at some depth and then goes deeper.
What would happen to the volume of air in the swim bladder if the fish didn't change the amount of air in it?
O The volume of air would decrease because of the decreasing pressure.
O The volume of air would increase because of the increasing pressure.
O The volume of air would decrease because of the increasing pressure.
O The volume of air would increase because of the decreasing pressure.

Part B
Will the fish need to add or remove gas from the swim bladder to maintain its neutral buoyancy?
O The fish will need to add gas, otherwise the fish will go deeper with decreasing speed.
O The fish will need to remove gas, otherwise the fish will go deeper with decreasing speed.
O The fish will need to remove gas, otherwise the fish will go deeper with increasing speed.
O The fish will need to add gas, otherwise the fish will go deeper with increasing speed.
