Answer:
No, they shouldn't because they´re incompatible
Explanation:
Compatibility among blood groups is given by the presence of <em>antigens</em> in the <em>red blood cells</em>, those are controlled by genes that can be either allelic or linked by proximity in the same chromosome. There are 33 blood groups system and approximately 300 antigens. The grouping is based on patterns of reaction in antisera testing. The most relevant blood groups systems for compatibility are:
ABO system: Refers to the presence of antibodies in the serum; A have antigen <em>A and contains antibodies against B; B have antigen B and contains antibodies against A, O doesn´t have antigens but contains antibodies against both, and AB have both antigens but doesn´t contain antibodies</em>
RH system: Rhesus system: Indicates the presence or absence of the immunogenic D-antigen, as RH+ or RH-.
<em> </em>
<em>Based on these concepts, an </em><u><em>O donor can only accept O blood type</em></u><em>, because it has antibodies for either A, B or AB, and transfusion will trigger </em><u><em>immunological response</em></u><em>, however, O blood type can donate to either group.</em>

Answer:
In economics, productivity refers to the ratio of what is generated to what is needed to manufacture it. This ratio is usually expressed as an average, with the total production of a group of goods divided by the total input of labour or raw materials, for example. The amount of output divided by the volume of inputs is generally referred to as productivity. In other words, it assesses how effectively a country's development inputs, such as labour and capital, are used to generate a given amount of output.
