Expert Solution & Answer

Answer to Problem 1TY

Option (d), a species that is in danger of becoming extinct throughout all or a significant portion of its range.

Explanation of Solution

Explanation/justification for the correct answer:

Option (d), a species that is in danger of becoming extinct throughout all or a significant portion of its range. Endangered species are those species that are on the verge of extinction throughout the world. Hence, this option is correct.

Explanation/justification for the incorrect answer:

Option (a), a species that is likely to become extinct in a portion of its range. Endangered species are not the ones whose population is decreasing in the given range but in the whole world. Hence, this option is incorrect.

Option (b), a species that has disappeared in a particular community but is present in other natural environments. Endangered species are not the ones whose population is decreasing in the given range but in the whole world. Hence, this option is incorrect.

Option (c), a species that is extinct. Extinct species are those species whose even one organism is not present on this planet to continue life. While endangered species are those with a limited population. Hence, this option is incorrect.

Option (e) is both b and d. Among the given options, option d is correct. Hence, this option is incorrect.

Conclusion

Among the answers given, a correct answer is an option (d), a species that is in danger of becoming extinct throughout all or a significant portion of its range.

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
