Why is a person with type AB blood able to receive a blood transfusion from a donor with any of the major blood types (A, B, AB,
Alisiya [41]

Answer:

ABO blood grouping system is based on presence or absence of three types of antigen on red blood cells. A and B blood group have A and B antigens respectively. AB blood group has both A and B antigens. O blood group does not have any antigen.

A body with particular blood type will consider other blood group foreign ( because it has different antigen ) and produce antibodies against it. A person with blood type A can not be given B type blood because the antibodies in his body will destroy RBCs with B antigen which may even prove fatal.

AB blood type person can receive blood from both A and B blood groups because he has antigens for both of them so it will produce antibodies for neither of them. He can also receive O type blood because O blood does not have any antigen so it can be given to any person without incompatibility reaction.  

However, AB individual can only donate blood to AB individual because his blood cells have both A and B antigens. So, he can only donate blood to an individual who does not produce antibodies for both A and B blood groups and that would only be another AB blood type individual.

Which the following statements typifies tropical rain forests? A. They are usually composed of at least ten distinct layers, or
Novosadov [1.4K]

        The right answer here is option C. They occur in areas with ancient, mineral-poor soil.

         An example of that is Amazonia in Brazil, it's one of the biggest forests on earth, and at the same time, we know its soil is poor, but at the same time it has some special materials that can be found there, such as niobium. This forest is, too, rainy almost all the time, and this many trees maintain the temperature of the whole earth stabilized. These kinds of forests can grow in this soil because of the burlap, that's organic materials from its own trees. It's consumed by them, and through this way, it survives and extends its size when humans don't use its resources too much.

Earth’s polar caps quickly losing ice. Coral reefs bleaching to a chalky white. Stronger storms devastating islands and cities, claiming lives and destroying homes. Those aren’t claims of what our world faces in a warmer future. Those climate change impacts are already happening — and due to worsen. That’s the finding of a new report from the United Nations Intergovernmental Panel on Climate Change, or IPCC. The United Nations issued a summary of the new assessment on September 25. It’s the panel’s first comprehensive update on how human-driven climate change is upsetting not only Earth’s oceans, but also its frozen regions, or cryosphere. Just how severe things get will depend on whether most countries lower their releases of climate-warming greenhouse gases — or just continue pumping large quantities of them into the air. The report focuses on two potential scenarios. One involves cutting greenhouse gases enough to limit global warming to around 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels. By the way, the world is already more than halfway there; global temps have warmed by 1.1 degrees C (2 degrees F) since 1900, according to a second new report. Prepared by the World Meteorological Organization, it was released September 22. In a second scenario, pollution continues at its current pace to where Earth eventually warms some 4 degrees C (7.2 degrees F). Science News for Students took a look at the report’s predictions. They offer a scary view of potential changes that would impact societies and our natural world. They’re based on the latest available science.
