Answer:

choice 2

Explanation:

Haemoglobin,in the normal adult,is a protein whose main function is to transport oxygen from the lungs to tissues and to transport carbon dioxide from tissue to lungs.The haemoglobin molecule contains four separate folded peptide chains,which form a hydrophobic or water repelling pocket around a heme group.Earthworm blood unlike that of invertebrates contains haemoglobin,a protein which carries oxygen throughout its body.It is present in the blood plasma and contains a red colour compound called heme.Heme contains an iron atom that binds to oxygen.The oxygen is picked up by haemoglobin dissolved in blood plasma and carbon dioxide is released.
