Which of the following is NOT an adaptation for deep diving in Cetaceans? Having a lot of myoglobin in the muscles to store oxygen Having increased hemoglobin concentrations to store more oxygen Slowed heart rate Blood flow is shifted from the brain to the extremities Collapsing the lungs to compensate for increasing water pressure during deep dives

Hence the correct answer is Blood flow is shifted from the brain to the extremities.

Explanation:

Blood flow is shifted from the brain to the extremities - most marine mammals have an in-depth network of blood vessels towards their brain which is understood because of the retia mirabilia. These reduce the temperature in the extremities.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
