If they are not exact as possible, the person receiving the blood or tissue or organ will reject it as foreign (doesn't belong).
Although you donate all of your blood components, only the red cells are given to someone who doesn't have your exact blood type. B type whole blood will only be given to B. An AB recipient will only get red cells and no plasma so the antibodies in the plasma can not attack the antigens on the red blood cell surface.
No, a Type AB blood donor could not give to a Type O recipient. The A & B refer to antigens, or proteins, on the surface of the red blood cells. Type O people have neither A nor B antigens, thus, their body rejects the donor blood, which has both A and B antigens. Here is a chart: Type Given Can Receive: O O, A, B, AB A A, AB B B, AB AB AB This is not exactly correct, but for the intents of your question, it should serve. The exact blood types would be O, A plus, A minus, B plus, B minus, AB plus, and AB minus.
Yes. A person with blood group antibody B can not donate blood to another person with group A because it will agglutinates as they blood group A can only be donated to to a person with blood group A. Even though you donate whole blood, all of it is not given unless you both have the exact blood type. A person with A type (who has B antibodies in their plasma) will only donate their cells. No antibodies will be given. So AB can be given A but without the plasma which has the antibodies.
Blood is classified by type:Type AType BType ABType OBlood is also classified by rhesus (Rh) factor, which refers to a specific antigen in the blood. If your blood has the antigen, you're Rh positive. If your blood lacks the antigen, you're Rh negative.At one time, type O negative blood was considered the universal blood donor type. This implied that anyone - regardless of blood type - could receive type O negative blood without risking a transfusion reaction. However, even type O negative blood may have antibodies that cause serious reactions during a transfusion.Ideally, blood transfusions are done with donated blood that's an exact match for type and Rh factor. Even then, small samples of the recipient's and donor's blood are mixed to check compatibility in a process known as crossmatching. In an emergency, however, type O negative red blood cells may be given to anyone - especially if the situation is life-threatening or the matching blood type is in short supply.see link below
Well blood type O+ can be given to anyone, but they can only receive their blood type. And O+ blood can be combined with certain materials that are found in A type or B type to make it another blood type. And people with a blood type of A or B or AB can only give their blood to people who have the same exact blood type as them.
Because they have no antibodies and can recognize both A, B, AB, and O donors. Their immune system has seen the "A" sugar and "B" sugar and "O" is acceptable because it is recessive to A and B (O is the universal donor)...
Type O negative blood does not have A or B antigens on its red blood cells, making it the universal donor blood type. It contains both anti-A and anti-B antibodies in the plasma to help fight against foreign antigens of blood types A and B during transfusions.
If the donor Jeep is the exact same year and has the exact same engine and transmission the answer is yes.
Demelza's exact age is unknown however she was between thirteen and fourteen in Half-Blood Prince.

Cloning is creating an exact genetic copy of something. To clone first take the nucleus from a donor cell, and collect some unfertilized eggs. Remove and replace an egg nucleus with the donor cell nucleus, and put the egg in a womb, for it to be born.
