Answer 2

$\huge\underline\mathbb\blue{{♡ANSWER♡}}$

$\purple\longmapsto\:$ Oxyhaemoglobin dissociation curve is obtained when percentage saturation of haemoglobin with O2 is plotted against the pO2.

$\purple\longmapsto\:$ At normal condition this curve is sigmoid and normal.

$\purple\longmapsto\:$ By increasing the concentration of CO2 ,the curve shifts towards right side.

$\purple\longmapsto\:$ By decreasing concentration Co2 the curve shifts towards left side.In this way the graph forms sigmoidal pattern.
