Apart from suffering from recurrent and prolonged infections, Marie Curie also experienced the following signs and symptoms: fatigue, rapid heart rate, pale skin, easy bruising, prolonged bleeding from cuts, and dizziness. Bone marrow transplant was not an option at that time and so blood transfusion was the treatment of choice.

Explain the reasoning behind these other signs and symptoms that Curie experienced. Assume her blood group was A negative. Which blood groups can she receive? Which blood groups can she not receive? Explain why.
