No, it is nowhere near "homeostasis." Perhaps it is a homeostatic mechanism or a natural immunological response of the body.
Correct answer: B). The phagocytotic barrier, which is a part of innate immunity
The scenario represents the phagocytosis, which is a type of endocytosis by which the cell engulfs microbial pathogens. The main cells of the immune system that are involved in phagocytosis include macrophages, neutrophils, and dendric cells.
It is a mechanism which is used by the immune system to kill and processing of antigen that play an important role in innate immune response.
Hence, the correct answer would be option B.
The answer is single nucleotide polymorphisms (SNPs)
It checks for variation in nucleotide sequences in particular genes that may be different among people, especially in different races. An example is a gene for melanin that would determine the trait for skin color. Single nucleotide changes in the gene between population can be used to differentiate populations.
