Answer:- E (O+)
Reason:- Blood group O+ has no antigens but both antibodies (anti-A and anti-B) and rhesus factor. It is the most common blood type.
Blood type A+ has type A antigen with presence of rhesus(Rh) factor.
Blood type B+ has type B antigen with presence of rhesus factor.
Blood type AB+ has both anti-A and anti-B antigens with the presence of rhesus factor.
Blood type O has no antigens but it may be with and without rhesus factor.

A model of a red blood cell portrays the cell as a spherical capacitor, a positively charged liquid sphere of surface area A separated from the surrounding negatively charged fluid by a membrane of thickness t. Tiny electrodes introduced into the interior of the cell show a potential difference of 100 mV across the membrane. The membrane's thickness is estimated to be 104 nm and has a dielectric constant of 5.00 (a) If an average red blood cell has a...

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...

5. Sickle-cell disease is an interesting genetic disease. Normal homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect. However, individuals with the heterozygous condition (Ss) have some...
