42. Which of the following is not part of the acid-growth hypothesis? (A) The wall fabric becomes looser (more plastic). (B) Auxin stimulates proton pumps in cell membranes. (C) The turgor pressure of the cell exceeds the restraining pressure of the loosened cell wall, and the cell takes up water and elongates. (D) Lowered pH results in the breakage of cross-links between cellulose microfibrils. (E) Auxin-activated proton pumps stimulate cell division in meristems.

43. Which of the following statements about bioenergetics is true? (A) A BMR can be determined only at a specific temperature. (B) Endotherms are warmed by metabolic heat. (C) Ectotherms and endotherms use the same basic energy "strategy." (D) Every animal has a specific metabolic rate that does not change. (E) An SMR is best measured just after an ectotherm has eaten.

44. Which of the following vertebrate organ systems does not open directly to the external environment? (A) circulatory system (B) excretory system (C) respiratory system (D) digestive system (E) reproductive system

45. Which of the following physiological responses is an example of positive feedback? (A) Stimulation of a nerve cell causes sodium ions to leak into the cell, and the sodium influx triggers the inward leaking of even more sodium. (B) The pituitary gland secretes a hormone called TSH, which stimulates the thyroid gland to secrete another hormone called thyroxine; a high concentration of thyroxine suppresses the pituitary's secretion of TSH. (C) The body's production of red blood cells, which transport oxygen from the lungs to other organs, is stimulated by a low concentration of oxygen. (D) A high concentration of carbon dioxide in the blood causes deeper, more rapid breathing, which expels carbon dioxide. (E) An increase in the concentration of glucose in the blood stimulates the pancreas to secrete insulin, a hormone that lowers blood glucose concentration.

46. The mammalian trachea and esophagus both open into the (A) stomach. (B) pharynx. (C) epiglottis. (D) rectum. (E) large intestine.

47. Individuals whose diet consists primarily of corn would likely become (A) malnourished. (B) overnourished. (C) undernourished. (D) anorexic. (E) obese.

49. Blood returning to the mammalian heart in a pulmonary vein will drain first into the (A) right ventricle. (B) vena cava. (C) left atrium. (D) right atrium. (E) left ventricle.

50. In negative-pressure breathing, inhalation results from (A) using muscles of the lungs to expand the alveoli. (B) relaxing the muscles of the rib cage. (C) contracting the diaphragm. (D) contracting the abdominal muscles. (E) forcing air from the throat down into the lungs.

51. Which of the following reactions prevails in red blood cells traveling through pulmonary capillaries? (Hb = hemoglobin)(A) CO2 + H2O → H2CO3(B) Hb(O2)4→ Hb + 4O2(C) Hb + 4 CO2 → Hb(CO2)4(D) H2CO3→H1 + HCO3-(E) Hb + 4 O2→ Hb(O2)4
