blood plasma
The differentiation among blood
groups results from the presence of a certain type of protein on the surface of

B antigen has the blood group AB.
Subduction is a land procedure that happens at united limits of structural plates where one plate moves under another and is constrained or sinks because of gravity into the mantle. Districts, where this procedure happens, are known as subduction zones.
Subduction is not generally joined by pressure and push blaming in the abrogating plate. This is particularly genuine when the overriding plate is either not pushing toward the subducted section in respect to the asthenosphere, or it is moving endlessly.
