Question

37. Which of the following statements regarding the data presented in the figure is false? A. Blood circulation to muscle was significantly reduced during the dives. 8 B. Circulating blood oxygen continued Arterial blood O, to be made available from oxygen in muscle. C. Muscles eventually accumulated lactic acid during the dives. Muscle O, 8 D. Oxygen supplies for the brain and myocardium remained higher than muscle during the dives Muscles switch to anacrobic metabolism at some point during the dives. E. 15 20 10 Length of dive (min) a 8 Ligand-gated channels on the postsynaptic membrane open and K' and Na both move through these channels in opposite directions. Why then do we measure depolarization on the postsynaptic A. Na" has a much stronger driving force into the cell B. K' has a much stronger driving force into the cell C. Na" has a much stronger driving force out of the cell D. K' has a much stronger driving force out of the cell E. K moves out of the cell, then back into the cell D. Suppose you are comparing blood samples and samples of alveolar gas from two native Peruvians resting in their dwellings-one at sea level and one at 4500 m altitude. The O2 partial pressure would likely be the most similar in A. their venous blood B. the ambient air in each of their locations. C. their alveolar gas. D. their arterial blood. E. the air in their tracheas. crustaceans. It gets much of its water as preformed and metabolic water from its food. However, it needs more water than its food provides, and the amount of additional water it needs increases as it lies more, because flight greatly increases its rate of evaporative water loss. The bat can c NaCI to about 620 mM in its urine. The concentration of Na' in seawater is 470 mM and concentration of Cl in seawater is $48 mM. Which of the following are true? (Mark all that apply). A. For H:0 to be acquired by drinking seawater, all the ions in the seawater (including Mg" and SO', not just Na, and Cl) must be more concentrated in the urine than in the seawater B. They could drink seawater, but it would eventually cause them to lose body water. C. They could not drink any seawater, and if they did they would rapidly dehydrate. D. The bats would be able to maintain their water balance by drinking seawater. . The evolution of higher metabolic rates in a species of freshwater fish would increase the challenge of maintaining body water balance because (Mark all that apply) A. their increased metabolism would cause them to lose more heat to the water and lower their body

Explanation / Answer

A. K+ hashas much more driving force out of the cell.

B. Their alveolar gas

C. The could drink seawater but eventually cause them to dehydrate.
