After a few days, Daisy starts to feel better and seems to have more energy for basic physical activities. Which one of the following adaptations would you have expected to see in Daisy after a few days in La Paz?Group of answer choicesHer erythropoietin levels will have increased and her hematocrit levels will have increasedHer metabolism has adapted to the low oxygen environment and has decreased metabolic rateHer breathing will return to normal sea level values as she has adapted to high altitudeHer blood flow has redistributed to better supply the essential organs

Daisy’s collaborator, Catalina also travelled from Melbourne to La Paz at the same time. While Daisy was feeling tired and unwell, Catalina felt no such effects. In talking with Catalina, Daisy found out that Catalina is Bolivian and actually grew up in La Paz and has family in the local area around La Paz who has been there for generations.Based on what you know about adaptations of different human populations that have lived at altitude, which of the following is the most likely explanations for the different responses that Catalina had compared to Daisy on arriving at high altitude? (Select all that are correct. There may be one or more correct options)Group of answer choicesAltered mitochondria energeticsIncreased anaerobic metabolism capacitiesGenetics varianceHigher hematocrit levels

Which of the following is not an adaptation in high altitude populations such as the Andes in South America or Tibetan Sherpa's of Nepal? Increase in lung size and volume. Increase in the number of red blood cells. Increase in the oxygen saturation of existing red blood cells. increased blood flow to the lungs.

Which of the following traits would provide adaptive benefits to an animal living at high altitude? (Select all that are correct. There may be one or more correct options)Group of answer choicesIncrease capillarity of musclesIncrease sensitivity to hypocapniaLarger muscle massIncrease haemoglobin oxygen binding affinityIncrease capacity for anaerobic metabolismGreater hematocrit

Sally, who lives mostly in Frankston travelled to La Paz in Bolivia (altitude 3625 m). They experienced shortness of breath. This is because their hemoglobin: choosing from below Binds oxygen more tightly in the lungs than a local. Binds oxygen more weakly in the lungs than a local. Binds oxygen more weakly in the tissues than a local. Binds oxygen more tightly in the tissues than a local.

Which of the following adaptations would you expect to see in diving mammals? (Select all that are correct. There may be one or more correct options)Group of answer choicesIncrease myoglobinIncrease tolerance to hypercapniaIncrease tolerance to acidosisExtreme bradycardia on diving
