Question 1. The best answer is C - antigen on the red blood.

The ABO  blood classification is based on the red blood cells. In summary:

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.

it would lead to upper respiratory infections and pneumonia.
