5. In what way would the change in heart rate that corresponds with holding your breath be advantageous in other types of organisms? What organisms might commonly exhibit such an adaptation?



Answer :

GinnyAnswer

Final answer:

Physiological adaptations in organisms like air-breathing vertebrates underwater and at high altitudes involve heart rate adjustments for oxygen supply.


Explanation:

Physiological adaptation involves changes in living organisms to better cope with situations or threats. For organisms like air-breathing vertebrates spending time underwater (e.g., seals, penguins), maintaining heart rate helps ensure brain and heart oxygen supply during diving. Similarly, acclimatization at high altitudes involves hyperpnea - increased breathing rate to intake more oxygen, with the heart beating faster initially.
