5. A decrease of blood pH from 7.4 to 7.2 causes hemoglobin to _______ .
(A) release all bound carbon dioxide molecules
(B) bind more oxygen molecules
(C) decrease its binding of H+
(D) give up more of its oxygen molecules

6. African lungfish, which are often found in small, stagnant pools of fresh water, produce urea as a nitrogenous waste. What is the advantage of this adaptation? (A) Urea takes less energy to synthesize than ammonia. (B) Small, stagnant pools do not provide enough water to dilute the toxic ammonia. (C) The highly toxic urea makes the pool uninhabitable to potential competitors. (D) Urea makes lungfish tissue hypoosmotic to the pool.

7. How has the avian lung adapted to the metabolic demands of flight? (A) Airflow through the avian lung is bidirectional like in mammals. (B) There is more dead space within the avian lung so that oxygen can be stored for future use. (C) Countercurrent circulation is present in the avian lung. (D) Gas exchange occurs during both inhalation and exhalation.

8. The loop of Henle dips into the renal cortex. This is an important feature of osmoregulation in terrestrial vertebrates because _______. (A) absorptive processes taking place in the loop of Henle are hormonally regulated (B) differential permeabilities of ascending and descending limbs of the loop of Henle are important in establishing an osmotic gradient (C) the loop of Henle plays an important role in detoxification (D) additional filtration takes place along the loop of Henle

9. An examination of a marine sea star that had died after it was mistakenly placed in fresh water would likely show that it died because _______. (A) it was stressed and needed more time to acclimate to the new conditions (B) it was so hypertonic to the fresh water that it could not osmoregulate (C) its kidney had ruptured (D) its cells dehydrated and lost the ability to metabolize

10. The transfer of fluid from the glomerulus to Bowman's capsule _______. (A) results from active transport (B) transfers large molecules as easily as small ones (C) is very selective as to which sub-protein-sized molecules are transferred (D) is mainly a consequence of blood pressure in the capillaries of the glomerulus

11. Among the following choices, which organism likely has the highest systolic pressure? (A) mouse (B) human (C) hippopotamus (D) giraffe

12. Hormone X activates the cAMP second messenger system in its target cells. The greatest response by a target cell would come from _______. (A) applying a molecule of hormone X to the extracellular fluid surrounding the cell (B) injecting a molecule of hormone X into the cytoplasm of the cell (C) applying a molecule of cAMP to the extracellular fluid surrounding the cell (D) injecting a molecule of activated, cAMP-dependent protein kinase into the cytoplasm of the cell

13. Steroid and polypeptide hormones typically have in common _______. (A) the building blocks from which they are synthesized (B) their solubility in cell membranes (C) their requirement for travel through the bloodstream (D) their reliance on signal transduction in the cell

14. A cluster of tumor cells that produces and secretes growth factors to induce surrounding cells to grow and divide is showing which type of cell-to-cell signaling? (A) autocrine (B) paracrine (C) endocrine (D) neuroendocrine

15. What happens in a cell when adenylyl cyclase is activated? (A) cAMP is created (B) cAMP is destroyed (C) G proteins bind to cAMP (D) steroid hormones pass through the lipid bilayer
