Answer:

The correct answer will be option-A

Explanation:

The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.

Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.

The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.

Thus, option-A is the correct answer.

<span><span>Organelles are tiny parts of a cell, in analogy are like organs. They perform various tasks vital for a cell to survive. They deliver information, send nutrients and excrete waste and protect cells from antibodies and other microorganisms that could and possible harm the cell itself.<span> </span></span>
Cells repair themselves through the process of cell division and mitotic process. <span>Mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure.<span>
