Human blood types in the abo blood group are identified by
group of answer choices

a. microscopic examination of white blood cells

b. a series of enzyme controlled reactions

c. antigen-antibody reactions

d. clotting factors in the plasma

C. antigen-antibody reactions

Explanation:

human blood group is determined by the presence of antigens on the red blood cells which are specific proteins.

so specific antibodies are used against these antigens to determine the type of blood group after the reaction.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
