(A transfusion of normal group O blood can trigger a severe transfusion reaction.). Because the H antigen is the precursor of the ABO blood group antigens, if it is not produced, the ABO blood group antigens are also not produced.f a person has blood group O, the H antigen remains unmodified. Therefore, the H antigen is present in the highest amounts in blood type O and in the least amounts in blood type AB. Two regions of the genome encode two enzymes with very similar substrate specificitiesâthe H locus (FUT1) and the Se locus (FUT2).
Today, very little honey is produced as comb honey. Comb honey is raw pure honey sections taken straight from the hive â honey bees' wax comb with no further handling at all. It is the most unprocessed form in which honey comes -- the bees fill the hexagon shaped wax cells of the comb with honey and cap it with beeswax.
So, a good rule of thumb is to be wary of ultra-filtrated honey, because there is a good chance it is smuggled honey from China or some other country. So, what should you do if you want good honey? Know The Source. Honey from local farmers is safe. Usually these farmers will not alter the honey in any way.
