(a) increase the value of Kp
(b) decrease the value of Kp
(c) increase the concentration of NOCl
(d) both a and b
(e) both a and c
I CHOSE (C) WAS MY ANSWER

When hemoglobin, Hb, reacts with oxygen, O2, we get oxyhemoglobin HbO2:

At high altitude, the partial pressure of O2 is lower. To get adequate HbO2 to live, an organism would likely
(a) produce less Hb
(b) produce more Hb
(c) reduce HbO2
(d) both b and c
