What happens to most of an ecosystem’s energy?

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.

Refer to the family pedigree shown here. in generation i, one parent is affected by the gene mutation and one parent isn't. in generation ii, all three children are affected by the gene mutation. what can you conclude about this gene mutation? a. all children born in future generations will be affected by this disorder. b. this gene mutation is a dominant disorder. c. this gene mutation is a recessive disorder. d. the generation i mother is a carrier of this gene mutation.

Aprocedure done under controlled conditions to test a hypothesis is an inquiry.
