Chapter 2, Problem 11TYU

SCIENTIFIC INQUIRY 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 isequipped 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.

General Biology 1   Summarize how signals are relayed between cells. Explain in great detail and depth and cover some information on how the signals are relayed between cells. Your explanation should cover a couple of paragraphs. Explain your answer in your own words and do not use other websites or online references to give your answer.
*Highschool Question: The vast majority of carnivores have tissues that sometimes have a lot of mitonchondria in their cells. What tissues are they? And why are they so rich in mitochondria?
SCIENTIFIC INQUIRY Prostate cells usually require testosteroneand other androgens to survive. But some prostate cancercells thrive despite treatments that eliminate androgens.One hypothesis is that estrogen, often considered a femalehormone, may be activating genes normally controlled by an androgen in these cancer cells. Describe one or moreexperiments to test this hypothesis. (See Figure 11.9 to reviewthe action of these steroid hormones.)
