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.

2. describe three situations in which ionic reactions go to completion.
Travka [436]

The  three situations in which ionic reactions go to completion is formation of a gas,  a precipitate and a slightly ionized product.

<h3>What are ionic reactions?</h3>

It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.

Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.
