Question 1 Test: charge the plates so that the electric field between them is strong enough to deflect positive or negative atoms. How
does the mass of an atom affect the amount a charged atom gets deflected?
a. The mass has no effect on the amount of deflection
b. Atoms with less mass get deflected more.
c. Atoms with more mass get deflected more

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.
