Classifying animals into different taxa can also reflect evolutionary relationships. Consider this cladogram with two main branches. It illustrates how anatomical changes resulted in various classifications.

Considering the cladogram, what statements are true about anatomical and evolutionary relationships? Click on all that apply.

Organisms starting at point A and to the right are all aquatic

Organisms at point C will have hair.

All organisms on the main right branch will have bilateral symmetry.

All of the organisms from point B on are terrestrial.

Organisms between points A and B mammary glands

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.
