I need help with all parts please
Transcribed Image Text:Below are data from a study of gas exchange
physiology of three different breeds of
domesticated yaks from Tibet. The different
breeds live at different altitudes. Note MCH is
the average amount of hemoglobin contained in
each red blood cell, while MCHC is the average
concentration of hemoglobin in a given volume
of red blood cells.

A. Based on our discussion of circulation and
gas exchange, explain the differences that we
see in the data among the different breeds of
yaks.
B. What experiment would you need to do or
what data would you need to collect to
determine whether the differences in gas
exchange physiology among the different
breeds of yaks is due to adaptation or
acclimation? Be sure to include the expected
outcomes that would be consistent with each
hypothesis (adaptation or acclimation).
