Textbook Question
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.
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.)
Honey bees are visiting two food sites, A and B, at 6 AM in the morning, as shown in Fig. 1 and Fig. 2. Bees at site A are collecting pollen; those at site B are collecting nectar. When bees from site A return to the nest, they must find a cell in the wax combs and store the pollen (Fig. 3). Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4).
16. True or False: In Fig. 4, the forager is passing a pheromone to the young receiver bee that slows the rate of JH increase resulting in the normal progression through the age-based division of labor. 17. True or False: If young bees are prevented from interacting with older bees as shown in Fig. 4, they will have reduced exposure to ethyl oleate, which will result in the upregulation of genes such as Am-for and per, their PKG and PER levels will increase, and they will become precocious foragers. 18. True or False: In Fig. 3, if a pollen forager accidentally loses her pollen pellets, she will…

- Honey bees are visiting two food sites, A and B, at 6 AM in the morning, as shown in Fig. 1 and Fig. 2. Bees at site A are collecting pollen; those at site B are collecting nectar. When bees from site A return to the nest, they must find a cell in the wax combs and store the pollen (Fig. 3). Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4). 19. True or False: If a sudden storm kills many of the foragers while out in the field, the interactions shown in Fig. 4 will be reduced, which will cause the JH titers of some younger bees to decrease so that they remain nurse bees longer to raise replacement foragers. 20. True or False: In honey bee workers, the per gene and the Am-for gene become active gradually as a bee ages, such that younger bees that remain inside the nest are arrhythmic in their behavior and have lower levels of PKG compared to older foragers.arrow_forwardHoney bees are visiting two food sites, A and B, at 6 AM in the morning, as shown in Fig. 1 and Fig. 2.

Bees from site B pass their nectar to young Receiver Bees when they return to the nest (Fig. 4). 1. True or False: At 6 AM, foragers for site A would orient their waggle runs 40 degrees to the left of vertical on the combs. 2. Ture or False: At 6 AM, foragers for site B would orient their waggle runs 105 degrees to the right of vertical. 3.

True or False: If foragers are still visiting site B at 10 AM, their waggle runs would be oriented 125 degrees to the right of vertical. 5. True or False: The ability of the foragers to track the passage of time and compensate for the movement of the sun is based on the biological clock located in the deuterocerebrum and involves a 24-hr period of cycling of the genes fem and am-dsx. 6. True or False: The pollen unloading behavior shown in Fig. 3 is a type of associative learning that involves conditioning of the proboscis extension reflex.arrow_forward

- * Cnidarians (which include jellies, sea anemones and corals) are classified by a unique type of cell, the cnidocyte (see p. 647 for review), which, when discharged, forcibly ejects a toxic barbed spear into prey. These "stinging" cells discharge when a trigger (cnidocil) on the surface of the cell is activated by a prey, causing Ca2* to rush into the cnidocyte. Water follows the Ca2+ resulting is a high osmotic pressure which leads to the explosive discharge of the barbed spear. Researchers have found that physical touch alone isn't enough to induce a cnidocyte discharge. Supporting cells, which can detect prey, are connected to several cnidocytes through neural connections, help regulate groups of cnidocytes. Using the description above, deduce the different types of sensory cells that operate cnidocyte discharge including the mechanisms that induce an action potential. 2.
