Which situation is most likely to cause an increase in interspecific competition? A. The number of female moose in a population declines due to a disease.

B. Two species of birds evolve to feed on seeds from different types of trees.

C. Part of a forest is cut down to construct a housing development.

D. A previously farmed field is allowed to develop into a meadow.

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.

Which of the following is not associated with invasive species?

Describe the impact of deforestation of both abiotic and biotic factors within the tropical rainforest.
