Will notices that crickets seem to chirp more frequently at night in june than they do in october. he asks himself, "how do temperature changes affect how often crickets chirp"? if he were to perform an experiment, which of these statements would be the best hypothesis?

a)crickets are inactive in october.
b)do crickets like warm weather better than cold weather? eliminatec)crickets chirp more frequently as temperature increases.
d)crickets chirp for many reasons, and temperature is probably one reason.

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.
