Answer #1

Open system , leuko-reduced packed red blood cells are separaeds RBCs by blood transfusion and are used widely for treatment of various diseases.

These packed cells are stored in refrigerated conditions, after asking anticoagulamts and necessary nutrient, for not more than 45 days. They are anyway recommended to be used as fresh as possible. Another storage alternative is cryopreservation - freezing post addition of glycerol or other compatible cryoprotectants. This process is cost as well as time intensive.

A red blood cell may carry an excess charge of about -2.5×10^−12 C distributed uniformly over its surface. The cells, modeled as spheres, are approximately 8 μm in diameter and have a mass of 9.0×10^−14 kg. 1) How many excess electrons does a typical red blood cell carry? (Express your answer to two significant figures.) 2) Does the mass of the extra electrons appreciably affect the mass of the cell? To find out, calculate the ratio of the mass of...

Sickle-cell anemia is caused by a single point mutation in the hemoglobin of human red blood cells. It is a recessive gene. People who have sickle cell anemia are homozygous recessive and suffer terribly from this disorder. Now I have stated in lecture that mutations are neither good nor bad. Rather it depends on how the mutation effects the survival of the species. If the mutation harms the survival of the species it is bad, if it helps the survival...
