  1. Someone with AB+ blood has red blood cells with the A, B and Rh _________ on the surface of their red blood cells.  They do not have any__________ circulating in their plasma. They are the universal recipient because they can receive any blood type in a transfusion without the danger of a __________ reaction.

Expert Solution

Ans) Someone with AB+ blood has red blood cells with the A, B and Rh antigens on the surface of their red blood cells.

Explanation- ABO blood group system of humans is a classical example of multiple alleles. It is based on the presence or absence of surface antigens, chemicals that can induce immune response.The RBCs of people with type A blood group contain A antigens, those with type B blood group contain B antigens, and those with type AB blood group has both A and B antigens. Rh antigens similar to 1 present and rhesus monkeys is also observed on the surface of RBC in humans.

They do not have any antibodies circulating in their plasma.

Explanation- People with the particular ABO antigen on their RBCs will have in their serum the antibody against the other antigens. Antibodies are proteins produced in response to antigens. Accordingly, the plasma of type A blood contains anti-B antibodies, type B blood contains anti- A antibodies but no anti-A and anti-B antibodies are present in type AB blood.

They are the universal recipient because they can receive any blood type in a transfusion without the danger of a clumping reaction.

Explanation- During blood transfusion, any blood cannot be used. The blood of a donor has to be carefully matched with the blood of a recipient before any blood transfusion to avoid severe problem of clumping that is destruction of RBC

People with type AB blood group have both A and B antigens on their red blood cells and no antibodies present in their plasma. So they acn receive blood transfusion from anyone, making them universal recipient

The cell membranes of mammalian red blood cells are permeable to urea. If red blood cells are dropped into a solution of urea that is identical in osmotic pressure (isosmotic) to the cytoplasm of the cells, although the cells do not swell and burst as quickly as when they are dropped simply into pure water, they eventually swell and burst. Explain. Also discuss how you would design a solution into which red cells could be placed without ever swelling. (Hint:...
