← Nature & AnimalsWhich outcome occurs when migrating birds exhibit abnormal air sac volume regulation during high altitude soaring?
A)Decreased oxygen uptake efficiency✓
B)Muscular atrophy from barometric stress
C)Increased susceptibility to parasitic infection
D)Enhanced thermal insulation capabilities
💡 Explanation
When air sac volume regulation fails during soaring, reduced barometric pressure affects oxygen diffusion via altered blood gas exchange kinetics in the lungs, decreasing oxygen uptake. Therefore, decreased oxygen uptake efficiency results, rather than muscular atrophy, parasitic infection or insulation, which are influenced by different physiological factors.
