Question

1.The universal donor is considered a universal donor because

A.it lacks antibodies, therefore it will not agglutinate if exposed to the other blood types
B.It lacks any of the antigens present on the other types, therefore the antibodies of the other blood types will not cause agglutination
C.it has both types of antigens present, therefore it will not agglutinate with the other blood types
D.it has both types of antigens and antibodies therefore it poses no risk of agglutination with the other blood types

2.A person With A+blood type can:
A.receive blood from A+,AB or O+
B..receive blood from A-,AB- or O-
C.receive blood from A-,A-, O+ or O-
D. can only receive blood from O-​

Answer 1

1. A: type o- is considered the universal donor. The important part is that type o doesn’t have antibodies.

2. C: I am assuming that you mistyped and that the C should read A+, A-, O+ or O-. You can find this information online by searching blood typing compatibility. But A blood will negatively react with the B antibodies meaning A can’t receive AB blood
