A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater
growth than a dry formula Alter testing each fertilizer on two different plants for one month, his data led to the
conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his
teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials
because
she did not believe the new formula helped plants grow better than the old formula
it was necessary to see data from more plants before the conclusion could be accepted
it was necessary to have tested the fertilizer on different kinds of plants
she thought he should test additional fertilizer formulas on the same two plants

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.
