Under normal physiological conditions in human beings,every $100 \ ml$ of oxygenated blood can deliver how much $O_2$ to the tissues (in $ml$)?

The chloride shift is observed for the movement of which of the following ions?

Oxyhaemoglobin is an unstable compound because

During respiration,$CO_2$ is transported in the form of:

What are the favorable conditions in the alveoli for the formation of oxyhemoglobin?

If $ppCO_2$ is high and pH is low,then it will result in:
$i$. increase in affinity of haemoglobin for $O_2$
$ii$. decrease in affinity of haemoglobin for $O_2$
$iii$. oxygen dissociation curve shifts to left
$iv$. causes release of $O_2$ for diffusion into tissue cells
$v$. $H^+$ and $HCO_3^-$ ions combine to form carbonic acid
