When bar-headed geese fly at very high altitudes (possibly over Mount Everest!), they breathe very thin air where the partial pr
essure of oxygen is very low compared to that at sea level. Which of the following adaptions would help the geese efficiently exchange gases when flying at high altitudes? ______ A) hemoglobin that has a high affinity for oxygen
B) hemoglobin that has a high affinity for carbon dioxide
C) hemoglobin that has a low affinity for carbon dioxide
D) hemoglobin that has a low affinity for oxygen
Answer:hemoglobin that has a high affinity for oxygen
Explanation:
Haemoglobin is the oxygen carrying pigment in blood. It performs this function because of the presence of iron at the center of the haemoglobin which coordinates reversibly with oxygen thereby aiding delivery of oxygen to cells. At high altitudes where air is thinner and the partial pressure of oxygen is lower than sea level, haemoglobin must develop a greater affinity for oxygen in order to carry the scarce oxygen to cells.
wanna know why my mom seems to rather- dislike me?- i mean like is it horomonal issues or whatever?! ;_; im confus3d here. can this be counted for a science question?- im not sure. its 12:00AM rn and im actually confused as if this is science or just me wondering the m0st random thingalings. :'D
