Question

Which are characteristics of type O blood? a: Has anti-A antibodies b: Has anti-B antibodies c: Has surface antigen O on its erythrocytes d: Has surface antigen A on its erythrocytes e: Has neither surface antigen A nor B on its erythrocytes

Answer 1

Answer:

E) Has neither surface antigen A nor B on its erythrocytes

Explanation:

Blood contains the blood fluid called plasma and blood cells of different types. The cells of the blood also contain antigens on their surface which could activate immune system to eradicate the pathogens.

On the basis of the presence of these antigens, the red blood cells are categorized into four types that is A,B, AB and O.

The person with blood group A will have A antigens on the red blood cells, B blood group will have B antigens on the blood group and with O blood group will not have neither A nor B antigen on its surface.

Thus, Option-E is the correct answer.

Answer 2

The characteristics of type O blood is that it has neither surface antigen A nor B on its erythrocytes. That is option E.

The ABO blood group are based on which of the two antigens, type A or type B, a person inherits from the parents.

It classifies blood types according to the different types of antigens in the red blood( erythrocytes).

These antigen are molecules that are either proteins or sugars.

They function to:

• transporting other molecules into and out of the cell,

• maintaining the structure of red blood cells, and

• detecting unwanted cells that could cause illness.

According to the ABO system,

• Absence of both antigens A and B results in type O blood.

• Presence of both antigens leads to type AB.

• Presence of either A or antigen leads to type A or B.

Therefore, the characteristics of type O blood is that it has neither surface antigen A nor B on its erythrocytes.
