Arrange these components of the mammalian immune system as it first responds to a pathogen in the correct sequence
pathogen is destroyed
lymphocytes secrete antibodies
antigenic determinants from pathogen bind to antigen receptor on lymphocytes
lymphocytes specific to antigenic determinants from pathogen become numerous.
only memory cells remain
i -> iii -> ii -> iv -> v
iii -> ii -> i -> v -> iv
ii -> i -> iv -> iii -> v
iv -> ii -> iii -> i -> v
iii -> iv -> ii -> i -> v

The correct order is III -> IV -> II -> I -> V

Explanation:

During the initial immune response, the antibodies present on B-lymphocytes binds to the antigenic determinant or epitope present on the pathogen.

This interaction between pathogen and lymphocyte trigger the production of more lymphocytes specific to the particular antigenic determinant. These B-lymphocytes then differentiates into memory B cells and plasma cells. Plasma cells secrete the antibodies against the pathogen.

These antibodies destroy the pathogen by making the pathogen recognized by phagocytic cells or by activating the complement system of the body and at the end, only memory cells remain in the body which is used to generate a quick immune response in subsequent infection. Therefore, the right answer is III -> IV -> II -> I -> V.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
