In Countdown #50, Jimmy Olsen interviews an incarcerated Joker about the murder of Duela Dent, who had called herself the Joker's Daughter. The Joker states that he never had any daughter, and expresses awareness of the Multiverse's existence and of shifts in reality. The Joker appears as he did before Batman #655.
All blood is made of the same basic elements, however not all blood is alike. There are eight common blood types. In an emergency, blood type O- can be given to anyone because it is most likely to be accepted by all blood types. O- is the Universal Donor. Type A+ can donate to A+, AB+. Type A- can donate to A-, A+, AB+, AB-.
More than just two blood types are not compatible with each other. The four basic types of blood are: A, B, AB, O(not counting Rh).Type A blood can only receive blood from type A and type O. However, type A blood can donate their blood to type A and type AB. Because if a person needs a blood transfer, it MUST be from a donor with a compatible blood type. Otherwise, the transfer will kill the recipient. More elaborately, bl â¦ ood types are determined by the presence of two types of compounds in the blood.
