In a transfusion involving the A and O blood types, does it make a difference which blood type belongs to the recipient and which to the donor?

Yes. Different blood types infused into another person can cause serious problems (unless the donor is O-).

Explanation:

O- can be used for anyone; it is the universal blood type.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less
