1. blood type A has antigen A on the red cell membrane.
2. blood type B has antigen B on the red cell membrane.
3. blood type AB has both antigen A and B on the cell membrane.
4. blood type O has no antigen at all on the red cell membrane.
Question 2. the best answer is b - transportation of oxygen.
Sickle cells have an abnormal type of hemoglobin that is unable to carry oxygen in the same capacity that normal, healthy hemoglobin does.
