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.
a feedback mechanism that maintains homeostasis
Explanation:
Anhidorosis mostly directly interferes with a feedback mechanism that interferes directly with a feedback mechanism that maintains homeostasis.
Since anhidorosis is the inability to properly or normally sweat, it affects the process of homeostasis.
Homeostasis is an important characteristics of life.
It is the ability of organisms to maintain and sustain a balance environment within and outside of them.
Sweating is one such process by which the body carries out homeostasis. On a hot day, the body produces sweat which evaporates and release latent heat to cool the body. This inability affects the intricate balance between the environment and the body.

Answer:
Regions of the digestive system can be divided into two main parts: the alimentary tract and accessory organs.
Explanation:
Answer:The best explanation is;
The materials undergo decay when they collide, which results in the heating and subsequent melting and rising of materials
Explanation: A protoplanet is an embryo formed in a protoplanetary disc which has passed through a melting phase that enables the formation layered interior
In protoplanets the effects of partial melting of the components due to heating produced by radioactive decay and pressures from forces of gravity there is segregation of the melt and igneous composition such that the heavier melted metal can sink and be over laid by the lighter igneous rocks
Therefore, the best explanation is that the materials undergo decay when they collide, which results in the heating and subsequent melting and segregation by the sinking of the heavier melted materials and rising of the lighter igneous materials.
Answer:
Migration.
Explanation:
When an individual leaves an area, they are migrating.
