If a DNA sequence reads: G-T-C-A-G-A-T-T-C, then which of the following would be an appropriate DNA hybridization probe that could be used to find a gene
located within this DNA sequence?

1) TAGTC
2)CUAAC
3)GUCUA
4)GTCTA

Photosynthesis uses co2 and cellular respiration produces co2. we call the point when the two processes are in balance--when there is no net production of co2--the compensation point. how might you limit one of the processes in order to achieve a compensation point?

How does photosynthesis show the conservation of mass and 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.
