3. Which among the following is correct about Blood Group B ?
[A] It has B antigen on its red cells and Anti A antigen in its plasma
[B] It has B antigen on its red cells and Anti B antigen in its plasma
[C] It has no antigens on its red cells but, anti A antigen in its plasma
[D] It has B antigen on its red cells but no antigen in its plasma
Show Answer
Correct Answer: A [It has B antigen on its red cells and Anti A antigen in its plasma]
Notes:
The red blood cells have both A and B antigens, but the plasma does not contain anti-A or anti-B antibodies. It has B antigen on its red cells and Anti A antigen in its plasma.
4. From which part, Coconut coir is obtained?
