The blood type "o negative" is known as universal donor because the red blood cells have no proteins. This means that they can mix with any other blood type with any variety of protein attatchment. Your question is a little confusing, but the answer is that when Karl Landsteiner discovered blood types in 1901 and scientists understood the way different blood types would interact, o negative blood became the universal blood type.

What blood type is called the universal recipient because people with it can take transfusions from anybody?
The blood type that is can be given to anyone is blood type O-. A person that has the blood type O- is called a universal donor because O- is compatible (as long as they are not an alien!). People with negative blood types can only take negative blood types. People with positive blood types can take either positive or negative, so that is why only blood type O- is the universal blood type, not O+. :) ~Ctmusicgirl7PCH=AB
Can an ab positive blood donate to an o positive?
It depends what you consider to be "blood". Whole blood, collected directly from a volunteer blood donor, is rarely used in modern transfusion medicine. Rather, whole blood is separated into blood components, predominantly red cells, platelets and plasma. Each component may then be transfused to a patient for specific needs. AB negative red cells or whole blood may be only transfused to AB recipients (Rh positive or negative). AB, Rh negative platelets mat be given to any blood type recipient. AB plasma (Rh is of no importance for plasma), considered the "universal" plasma, may be given to any blood type recipient and is always in extreme shortage.

If a donor recipient dies can the organ be re used?
Usually the donor's transplanted organ is not transplanted again - it puts a lot of stress on the organ. And depending on how long the donor recipient has been on immuno-suppression for, some of the other organs may not be used (it can affect the kidneys a lot).
What blood can you transplant with O blood?
A person with O- (O negative) blood is considered a universal donor. That means that every blood type that exists can receive blood from a person with O- blood. (A+, A-, B+, B-, AB+, AB-, O+, O-) A person with O+ (O positive) blood, on the other hand, can donate to any type as long as it is positive. ( A+, B+, O+ or AB+)
Which law helps to allow donation without cost to the donor?
I think you may be talking about income tax deductions, possibly. These actually aren't "without cost to the donor', since the deduction applies to income, not the amount of tax due. It does mean that giving a charity $100 may only "cost" the donor $80 or so in the long run, since otherwise the donor would have been required to pay taxes on the $100.
What blood type can blood type ab receive?
Type ab blood can receive types a, b, ab, and o blood, not just type ab blood. Type ab is known as the "universal receiver", as it can receive any blood type, while type o is the "universal donor", meaning type o can be given to any person.
