For this assessment, you will:

examine the animals and plants that live around your home or in a local park
choose one kind of plant or animal that lives there- Mountain lion
identify the specific species name of the plant or animal that you chose- Puma concolor
choose five factors that might limit the size of the population of this species
identify each of your five limiting factors as a biotic or abiotic factor

Connection compare and contrast genetic engineering to the process of natural selection. select all statements that are true.

Which statement describe events that occur during interphase?

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.
