Project: Blood Typing In the early 1900s, the Austrian immunologist Karl Landsteiner discovered that all blood is not the same. Blood serum drawn from one person clumped when mixed with the blood cells of another. The clumping was caused by different antigens, proteins, and carbohydrates that trigger antibodies and fight infection. Landsteiner classified blood types based on the presences or absence of the antigens A, B, and Rh in blood cells. The Venn diagram in the figure below contains eight regions representing the eight common blood groups. A AB AB A 0 R Human blood types In the Venn diagram, blood with the Rh antigen is labeled positive and blood lacking the Rh antigen is labeled negative. The region where the three circles intersect represents type AB*, indicating that a person with this blood type has the antigens A, B, and Rh. Observe that type A, B, and Rh. O blood (both positive and negative) lacks A and B antigens. Type O lacks all three antigens, In blood transfusions, the recipient must have all or more of the antigens present in the donor's blood. This discovery rescued surgery patients from random, often lethal transfusions. This knowledge made the massive blood drives during World War I possible. Eventually, it made the modern blood bank possible as well. Complete each question below, taking care to justify clearly your reasoning as to why you selected your answer.

Explain in reference to the explanation above and in terms of the Venn diagram. Question 2: What is the blood type of a universal donor? Explain in reference to the explanation above and in terms of the Venn diagram. Question 3: Answer and explain in the mathematical context. a. Can an A person donate blood to an A person? b. Can an A person donate blood to an A* person? Reflect: What is your potential impact in a crisis? Are you a universal donor? Are you a + or -?
