Answer 2

A) O and B can give blood to blood group B.

• Blood group B has antigen B and hence it contains antibody A.
• The blood group O does not have any antigen.
• So, the B blood group can take up blood only with B antigen or blood lacking any antigen.
• Hence, both B and O blood can be given to the person with blood group B.
• The blood group O has both antibodies.
• The blood group A has antigen A and antibodies against B.
• The blood AB has both antigens A and B. But it lacks antibodies.
• The positive and negative blood group is determined by the presence of the Rhesus factor or Rh factor.
• It is also a protein present on the surface of Red Blood Cells.
