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 molecule and fly toward their source. The sensory organs responsible for this behavior are the tomblike antennae visible in the photograph shown here. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. (a) 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. (b) Describe predictions your hypothesis enables you to make. (c) Design an experiment to test one of these predictions.

- Hello, May I get help with this question? I do not understand it, steps leading to the correct answer would be helpful. Question: Bruce B. was deep in the woods and drank something he probably shouldn't have (why do people keep doing this?!?!). He's with a medical doctor and trained outdoorsman who tells him that, if he doesn't get treatment immediately, the toxins in the fluid will start to lock tropinin in place just in the sarcomeres in his digestive system. He asks you, an actual physiologist, what this means and what parts of digestion, secretion, absorption, and motility will be affected. Which of the following will be MOST affected...(see image)arrow_forwardWhich mathematical equation describes their growth?arrow_forwardBiology Cell adhesion can often be blocked in vitro by treating cells with specific agents.

- * 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.

Salmon are anadromous fish and must deal with osmotic changes in their environment in extreme ways. Researchers have found that Na*/K* - ATPase is found in two different kinds of cells in the gill tissue. One type is found in the filament bases that appear to be active when salmon are adults only. The other types of cells are found in the lamellae folds and appear to be active during its juvenile stages. Speculate on these findings as to how this allows salmon to complete their unique life cycle.arrow_forwardThis examples of mathematical pattern. 1.

- α-Bungarotoxin is a powerful neurotoxin found in the venom of a poisonous snake (Bungarus multicinctus). It binds with high specificity to the acetylcholine receptor (AChR; an integral membrane protein) andprevents its ion channel from opening. This interaction was used to purify AChR from the electric organ of torpedo fish.(a) Outline a strategy for using α-bungarotoxin covalently bound to chromatography beads to purify the AChR protein.
