Study the table above. A frog population was introduced to a new habitat. Two phenotypes for color of this particular species of frog exist: brown and green. What conclusion can be drawn about the frog's proportions as new generations are produced? Also, what type of environment is the frog's new habitat?
A) The green frogs are more tolerant of the weather in this new habitat; forest
B) The brown frogs numbers are dwindling because the green frogs are better suited for mating; desert
C) The alleles for brown color are most likely recessive and therefore do not pass down to generations as easily; desert
D) The alleles for green color outnumber brown because these frogs are better suited for survival in this habitat; forest

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.
