Why is blood type ab+ considered the universal receiver?

Well, there are four main blood types with two variations of each (so 8 in all):
A+
A-
B+
B-
AB+
AB-
O+
O-
Now, A blood has the presence of the A antigen in it, and so it can't mix with B blood (most of the time).
B blood has the B antigen.
AB has BOTH antigens in it
O has no antigen whatsoever.
So if AB has both antigens, wouldn't it be able to receive antigens from A and/or antigens from B? And same with O, which has no antigens, which has no effect on whatever type of blood it's introduced in (which is why O is considered "the universal donor").
Now, the difference between + & - is simple, and has almost no impact on a person. If a person has +, they have Rh in their blood (it's another type of antigen), and if a person has -, the Rh factor isn't there. So if a person has positive, they have Rh, so more Rh blood can be added to it, and so can blood without the presence of Rh.
Hope this helps!

Answer from: kamorex

AB+ blood group is considered as the universal receiver because it has no antibodies that can attack the antigens on the red blood cells of the other blood types.

Further Explanation:

The blood group system (ABO) in human beings is classified by the availability of a particular antigen present on the red blood corpuscle. The presence of allele IBi or IAi helps in classifying whether the antigen B or A is attached to RBCs. If the allele iO is present, that means no antigen is attached.

Thus, the table represents the present of the allele in different blood group:

Blood group GenotypeAntigen present on red blood cell

AIAIA or IAiA

BIBIB or IBiB

OiiA and B

ABIAIBnone

The A (blood group) has only A antigen and B (blood group) has only B antigen. The blood group AB has B and A antigens present on the RBC. Any infusion between the B and A blood group is not possible due to the production of specific antibody against the antigen by the body. Whereas, the AB blood group consist of both B and A antigen thus it can accept A, B and O blood group. It has not antibody that can attack. Thus, an individual with AB blood group is a universal receiver.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
