Which of the following will the adult butterfly exhibit to conserve water while flying under hot conditions? a. It will increase the release of diuretic hormone, which will inhibit the Na+/H+ and K+/H+ antiporters on the lumen side of the Malpighian tubule epithelial cells, thereby reducing the concentration gradient of ions across the walls of the Malpighian tubules and reducing the movement of water into the tubules through the paracellular pathway. b. It will increase the release of proctolin, which will inhibit the proton pumps in the Malpighian tubule epithelial cells, thereby causing more ions and water to be retained in the hemolymph. c. It will increase the release of hyperglycemic hormone, which will stimulate the fat bodies to increase the conversion of trehalose into glucose, thereby creating a higher hemolymph glucose concentration that causes water to be retained in the body. d. It will increase the release of antidiuretic hormone, which will cause the cells of the rectal glands to increase the active transport of Na+ and K+, thereby creating a stronger concentration gradient that draws more water from the rectum back into the hemolymph. e. a and b will both happen to conserve water. f. c and d will both happen to conserve water.
An adult female butterfly is actively flying from flower to flower while feeding on a very hot, sunny day in July. The adult butterfly developed from an egg that was laid late in the season the previous year and it became cold while she was still in the caterpillar stage. The caterpillar entered diapause and then resumed feeding and development the following spring when it became warmer. Before entering diapause, the caterpillar was
