Explanation:
Detailed explanation-1: -The normal time of RBC senescent (age-related) death in adults is approximately 110 to 120 days. Hemolysis can therefore be arbitrarily defined as a shortening in the survival of circulating RBCs to a value of less than 100 days.
Detailed explanation-2: -Answer and Explanation: The correct answer is (3) Erythrocytes lack a nucleus. Erythrocytes are red blood cells (RBCs). Mature and circulating RBCs do NOT have a nucleus.
Detailed explanation-3: -Red blood cells have a limited lifespan because they don’t have a center membrane (nucleus). When a red blood cell travels through your blood vessels, it uses up its energy supply and only survives an average of 120 days.
