Answer:

hiiii too don't know sry can't help u out

Answer 2

If a prrson’s blood has A antigen it can donate blood to people with A antigen blood group( a and ab blood group)

If a person’s blood has B antigen it can be donated to people with B antigen blood group( b and ab blood group)

If a person’s blood has no antigen, it is O blood group. Ppl with o blood group can donate blood to anyone.

If a person’s blood has RH protein, it is positive blood group. If RH protein is not present, it is negative.
People with positive blood group cannot donate to people with negative blood group, but the vice-Vera is possible.

Thus, we can conclude that O negative is universal donor, while O positive is universal recipient

Hope this will help
