$100 \ ml$ of oxygenated blood contains:

How much higher is the affinity of carbon monoxide for hemoglobin compared to oxygen (in $\times$)?

What is the chloride shift responsible for transporting?

Body tissues obtain ${O_2}$ from oxyhaemoglobin because of its dissociation caused by:

$I.$ Increased partial pressure of $O_{2}$
$II.$ Increased partial pressure of $CO_{2}$
$III.$ Increased partial pressure of $H^{+}$
$IV.$ Decreased partial pressure of $O_{2}$
All the above situations favour the dissociation of oxyhaemoglobin except:

When temperature decreases,the oxyhaemoglobin dissociation curve will become:
