Body tissues obtain $O_2$ from hemoglobin. The dissociation of oxyhemoglobin in the tissues is primarily caused by which of the following conditions?

People living at sea level have around $5 \; million$ $RBCs$ per cubic millimetre of their blood,whereas those living at an altitude of $5400 \; m$ have around $8 \; million$. This is because at high altitude:

Carbon monoxide combines with haemoglobin to form . . . . . . .

During oxygen transport,the oxyhaemoglobin at the tissue level liberates oxygen to the cells because

The dissociation curve is associated with
