Questions Related to fluid connective tissue

Which of the following is a universal blood donor?

biology animal tissues fluid connective tissue tissues of animals animal tissues and its type

  1. A

  2. B

  3. AB

  4. O

Show answer
Correct Option: D
Explanation:

A person with blood group O is considered as universal donor as it does not contain any antigens which can trigger the production of antibodies in a person with any of the other three blood groups i.e. A, B or AB. Thus, option D is correct.

How many possible genotypes are there for ABO blood groups in man?

  1. Three

  2. Four

  3. Six

  4. Eight

Show answer
Correct Option: C
Explanation:
 Genotype   Blood types
 $I^AI^O$ or $I^AI^A$ A blood type
 $I^AI^B$  AB blood type
 $I^BI^O$ or $I^BI^B$  B blood type
 $I^OI^O$  O blood type

There are six possible genotypes for the ABO blood groups in human.
The chart here shows the different genotypes, that make up the blood groups.
Therefore, the correct answer is option C.

Which of the following blood group is a universal donor?

  1. $AB^{+ve}$

  2. $O^{+ve}$

  3. $AB^{-ve}$

  4. $O^{-ve}$

Show answer
Correct Option: D
Explanation:

People with type O- negative blood are the universal donor for the whole blood. That means that, anyone can receive this blood type. Being O- negative, this blood group is compatible with all the blood groups, A${^+}$and A${^-}$ve, B${^+}$ve, B${^-}$ve, and AB${^+}$, AB${^-}$ve. And the chances of rejection is the least.
Therefore, the correct answer is option D.

A person with blood group O has

  1. Only anti- A antibodies

  2. Only anti- B antibodies

  3. Both anti- A and anti- B antibodies

  4. Both A and B antigens

Show answer
Correct Option: C
Explanation:

The blood group found in human beings are of four principal types: A, B, AB and O. These types are differentiated on the basis of two antigens A and B and two antibodies A and B present in the blood types. The specific combination of antigens and antibodies determines an individual's blood type. A person with blood group O has no antigen on the surface of the RBC but has both, anti- A and anti- B antibodies in his plasma.

Therefore, the correct answer is option C.
