Seawater is highly saline, which means it contains large amounts of dissolved salt. When seawater freezes and icebergs
form, the water in the iceberg doesn't take the salt with it. What effect will this phenomenon have on the concentration of
salt in the water around the iceberg?

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.
