1. Tom and Jane participate in a Red Cross blood drive. Both are first-time donors. As part of the screening process, their blood is typed. Tom is A+. Jane is AB+. 1.1. What ABO antibody is found in Tom’s blood?

Antibody B

Explanation:

According to the ABO antibody grouping, there are two types of antibodies (antibody-A and antibody-B) in the plasma as well as two antigens (antigen A and antigen B) in the red blood cells.

When an individual has a blood group A, he/she has Antigen A in the red blood cell and antibody  B in the plasma.

When it is blood group B, the individual has antigen B and antibody A.

When the blood group is O, the individual has no antigens but have antibody A and antibody B.

When the blood group is AB, the individual has no antibodies but have Antigen A and antigen B

Therefore, Tom has antibody B in his blood because he is A+

ANTI- B ANTIBODIES

Explanation: ABO blood group system is the classification of human blood based on the inherited properties of the red blood cell(erythrocytes) which are determined by the presence or absence of the antigen A and B carried on the surface of the red blood cell.

The four(4) main blood groups that are defined by the ABO system are; A, B, AB and O.

BLOOD GROUP A; Has A antigens in the red blood cell with anti- B

antibodies in the plasma.( Which correlates with Tom's)

BLOOD GROUP B; Has B antigens in the red blood cell with anti- A antibodies in the plasma.

BLOOD GROUP AB; Has A antigens and B antigens in the red blood cell and no antibodies in the plasma.

BLOOD GROUP O; Has no antigens but has both anti- A and anti- B antibodies in the plasma.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
