Your Lab Partner gets a Microtiter Pipette and the appropriate Microtiter Pipette Tips, sets this Microtiter Pipette Dial to 0 | 5 | 0 and adds this Amount of Fluid to an empty Sterile MicrocentrifugeTube. You get a Microtiter Pipette and the appropriate Microtiter Pipette Tips, set your Microtiter Pipette Dial, and with this set Amount, add Fluid to this same Sterile MicrocentrifugeTube to bring its Total Volume of Fluid to 1.0 ml. To do this, you should set your Microtiter Pipette Dial to :

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.
