Question

An individual has 'O' blood group if his/her blood sample _______
a. Clumps only when antiserum A is added
b. Clumps only when antiserum B is added
c. Clumps when both antiserum A and antiserum B are added
d. Does not clump when either antiserum A or antiserum B is added

Answer 1

Hint: Blood consists of red platelets, white platelets, and platelets in a fluid called plasma. Your blood group is distinguished by antibodies and antigens in the blood. Antigens are protein atoms found on the outside of red platelets.

Complete answer:
- There are four sorts of blood groups according to the ABO blood group framework. These are A, B, AB and O. Individuals with A blood group have antigen A on its RBC and antibodies B in the blood.
- Also, an individual with the B blood group has antigen B on its RBC and antibodies in the blood. An individual with an O blood bunch has no antigen on its RBC and An and B antibodies in the blood.
- An individual with AB blood group has both An and B antigen on the RBC and no antibodies are available. An individual is said to have an O blood group when her/his blood test doesn't cluster when either antibody A or B is included.
- This is on the grounds that he/she isn't conveying any antigen with which antiserum An or B will respond and shape a group.
- A portion of these antigens is additionally present on the outside of different kinds of cells of different tissues.
- A few of these red platelet surface antigens can originate from one allele (or an elective rendition of quality) and aggregately structure a blood group framework.
- Antibodies are proteins found in plasma. They're important for your body's common safeguards.
- They perceive unfamiliar substances, for example, germs, and caution your invulnerable framework, which pulverizes them.

Hence, the correct answer is option (D).

Note: A blood classification (otherwise called a blood gathering) is a characterization of blood, in view of the presence and nonappearance of antibodies and acquired antigenic substances on the outside of red platelets (RBCs). These antigens might be proteins, starches, glycoproteins, or glycolipids, contingent upon the blood bunch framework.
