What is the role of TNF family members in the development of peripheral or secondary lymphoid organs.
slamgirl [31]

The growth of lymphoid tissue in the gut is fueled by TNFa. Because TNF/Rorc(gt)/ mice, who express higher amounts of TNF but lack RORgt+ LTi cells, also generate lymphoid tissue in sites of inflammation, the development of this ectopic lymphoid tissue was not contingent on the presence of conventional RORgt+ LTi cells. Surprisingly, these animals produced a number of lymph nodes that resembled those of wild type animals in both structure and function. When stromal cells were activated during the late stages of embryogenesis and when an organogenic pathway that permitted the formation of lymph nodes was activated, TNF generation by F4/80+ myeloid cells located inside the anlagen was crucial.

Which of the following is NOT one of the
Dimas [21]

The way that does not successfully classify protists is their size. Thus, the correct option is C.

<h3>What are Protists?</h3>

Protists may be defined as one of the diverse taxonomic groups and particularly a kingdom of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that generally include the protozoans, most algae, and often some fungi.

On the basis of the way that Protists reproduce, they can be subdivided into three types: Sexually reproducing protists, asexually reproducing protists, and conjugation-based.

On the basis of how protists get energy and food, they are again subdivided into three categories.

  • Animal-like protists: Heterotrophs that have the ability to move.
  • Plant-like protists: Autotrophs that have the ability of photosynthesis.
  • Fungi-like protists: Heterotrophs have cells with cell walls.

On the basis of the way that they move, they are subdivided into two types: Motile protists and non-motile protists. They generally move with the help of cilia, flagella, and pseudopodia.

Therefore, the size is not one of the following ways that protists are grouped. Thus, the correct option for this question is C.
