Earth’s atmosphere helps to regulate its temperature. However, the addition of gases such as (1) causes more energy to radiate back toward Earth. As a result, the atmospheric temperature increases over time. If Earth had no atmosphere, it would radiate nearly as much energy as it receives from the Sun. This implies that the temperatures on Earth would be(2) Earth’s current temperature.

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.
