Final answer:

For a person with A+ blood type, B+ and B- blood types are incompatible because they contain B antigens that would provoke an immune response in an A+ individual.

Step-by-step explanation:

When considering blood type compatibility for donation, it is crucial to understand that certain blood types cannot be mixed or transfused without causing an adverse immune response. A person with blood type A+ can receive A+, A-, O+, and O- blood. The compatibility is based on the presence of certain antigens on the surface of red blood cells, as well as antibodies in the plasma. For A+ individuals, receiving blood types that contain B antigens, such as B+ and B-, would be incompatible and potentially dangerous because the person's immune system would recognize the B antigens as foreign and mount an immune response against them.
