The first system to classify blood types is known as<u> A-B-O system</u>.
<u>Option: D</u>
<u>Explanation:</u>
The blood group system "ABO" is the categorizing of human blood centered on the hereditary characteristics of red blood cells means erythrocytes as measured by the presence or absence of A and B antigens on the surface of the red cells. Thus individuals may well have blood type A, type B, type O or type AB.
It was absent until 1900, when Karl Landsteiner established the concept at the Vienna University why some blood transfusions were effective while others were lethal. Landsteiner established the blood group mechanism ABO by combining each of his staff's red cells and serum.

It is their properties. it is made up naturally due to the ions
Answer:
76.1 amu
Explanation:
Let us recall that isomers refer to two different compounds with the same molecular formula but different atom to atom connectivity and different chemical properties. When two compounds are isomers, we can essentially represent them with exactly the same molecular formula.
Now propane-1,2-diol and propane-1,3-diol are both represented by the molecular formula C3H8O2 since they are isomers of each other. When two compounds have the same molecular formula, they must essentially have the same molecular mass. Hence the molecular mass of propane-1,3-diol is also 76.1 amu.
