Female silkworm moths (bombyx mori) 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 comb like antennae
visible in the photograph shown here. each filament of an antennais 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.
