Question

The passage suggests that during laboratory dives, the pH of the Weddell seal's blood is not adversely affected by the production of lactic acid because:

Options:

A . Only those organs that are essential to the seal's ability to navigate underwater revert to an anaerobic mechanism

B . The seal typically reverts to an anaerobic metabolism only at the very end of the dive

C . Organs that revert to an anaerobic metabolism are temporarily isolated from the seal's bloodstream

D . Oxygen continues to be supplied to organs that clear lactic acid from the seal's bloodstream

Answer: Option C
:
C
It is evident from the following lines: “… since the anaerobic metabolism occurs only in those tissues which have been isolated from the seal’s blood supply, the lactic acid is released into the seal’s blood only after the seal surfaces…” that the pH of the Weddell seal’s blood is not adversely affected by the production of lactic acid because organs that revert to an anaerobic metabolism are temporarily isolated from the seal’s bloodstream. Therefore, answer option (c) is the correct answer choice.
