Vedclass · Answer

(B) Haemoglobin is a respiratory pigment found in many animals. In earthworms $(Pheretima)$,haemoglobin is not contained within red blood cells but is found dissolved directly in the blood plasma. In mammals,haemoglobin is a complex conjugated protein (not a dipeptide) localized within the red blood corpuscles $(RBCs)$.
