If a "blood sample" from the lab reacted with anti-A antibodies, but not anti-B antibodies, what would the blood type be?Group of answer choicesAOBAB

Breakdown of the Problem

1. Identify the significance of the reaction with anti-A and anti-B antibodies.
2. Determine what each reaction indicates about the blood type.

Relevant Concepts

1. Blood types are determined by the presence of specific antigens on the surface of red blood cells:
   • Type A has A antigens and reacts with anti-A antibodies.
   • Type B has B antigens and reacts with anti-B antibodies.
   • Type AB has both A and B antigens and reacts with both anti-A and anti-B antibodies.
   • Type O has no A or B antigens and does not react with either.

Analysis and Detail

1. Given that the blood sample reacted with anti-A antibodies, this indicates the presence of A antigens.
2. Since the sample did not react with anti-B antibodies, it means that there are no B antigens present in the blood.

Verify and Summarize

• The presence of A antigens and the absence of B antigens confirm that the blood type must be A.

Final Answer

The blood type is A.
