Erythrocytes have no nuclei. Without nuclei, erythrocytes can carry a higher amount of haemoglobin explain how this is an advantage in exchanging and carrying oxygen

The correct answer is - hemoglobin binds with respiratory gases such as oxygen so more hemoglobin will carry more oxygen .

Explanation:

Red blood cells have adapted the trait of having no nucleus for several reasons but the major reason is to increase the amount of hemoglobin so this can carry more oxygen to various parts of the body from lungs. If there will be more hemoglobin then it will allows RBC to transfer more oxygen.

Hemoglobin is the respiratory pigment that has four heme group, containing iron ion, arround globin group, each iron ion in the heme can bind to one oxygen molecule; So one molecule of hemoglobin can transport four oxygen molecules as it binds with oxygen.
