Some types of fish have a gas bladder that can fill with air. This bladder has vascular tissue that fills the bag with oxygen, a gas gland that regulates the amount, muscle tissue that squeezes the bladder to let out air and nervous tissue that allows the fish to control the amount of air in the bladder. The gas bladder is an example of which level of organization in fish?

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
