Chapter 2, Problem 11TYU
SCIENTIFIC INQUIRY
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 molecule and fly toward their source. The sensory organs responsible for this behavior are the tomblike antennae visible in the photograph shown here. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. (a) 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. (b) Describe predictions your hypothesis enables you to make. (c) Design an experiment to test one of these predictions.

A resting muscle fiber or neuron has an internal charge that is A. positive, B. negative, or C. neutral compared to the extracellular environment. This resting membrane charge is maintained by the A. calcium ion channels, B. sodium voltage gates, C. potassium voltage gates, or D. sodium/potassium pumps? .
When a muscle fiber is at resting membrane potential there is a(an) "higher", "equal", OR "lower" concentration of sodium inside the cell compared to outside the cell and a(an) "higher", "lower", OR "equal" concentration of potassium inside the cell compared to outside.
