Study the diagram. an ocean with points labeled 1 through 6. water level scale is on the left, from 0 kilometers to 15 kilometers. 1: inset of earth with arrow showing direction of rotation. 2: unstable atmosphere with a line graph showing air temperature change based on altitude. as the altitude decreases, the air temperature increases. 3: seawater greater than or equal to 80 degrees down to 50 meters or more. 4: convection occurs at the low pressure center. 5: a line graph showing wind speed increasing as altitude increases. 6: a 3 kilometer tall band starting 3 kilometers above water level. what is forming in the diagram?

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.
