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:
a. Its consideration of environment impact (such as accommodation for fish) became a model for future dam projects on western rivers
Explanation:
The Columbia River project was a project of great significance for the whole region, especially for the state of Washington. This project had many positive impacts such as production of electricity, irrigation for more than half of the farmlands, development of the area, opening up new jobs. One very big problem though was the impact on the species of fish in the river. As most of them are migratory species, with the building of the dam they were stopped in their movement, thus they became restricted to the upper part of the river. Also, the water and composition of the water changed, and all of these things contributed to significant reduction of the populations of the native species of fish.
This is trueeeee absolutely
