Why are red blood cells anucleated?

Why are red blood cells anucleated? Correct Answer Absence of nucleus leads to increased space for haemoglobin that carries molecular oxygen

Red blood cells (RBCs) present in human blood stream do not contain nucleus. Absence of nucleus leads to more space for stuffing of haemoglobin that carries molecular oxygen. This thus increases the oxygen-carrying capacity in blood. If the nucleus was present, haemoglobin content will be limited around the periphery. Furthermore, due to absence of nucleus, RBCs contain a disk-like depression that increases the surface are for haemoglobin content.

The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.

The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: It’s a type of cancer of the blood cells caused by a rise in the number of white blood cells in the body.  Q: There is hardly anything you can do to prevent leukaemia. R: If a person appears pale, swollen gums, an enlarged liver or spleen, significant bruising, bleeding, fever, fatigue, the doctor should suspect leukaemia. S: They crowd out the red blood cells and platelets the body needs to be healthy. All those extra white blood cells don’t work right, and that causes problems.
