Thymocytes with very low interaction avidity with self MHC of no potential value because these thrombocytes cant able to detect antigens.
In order to detect the antigen, thrombocytes must see them in the context of self-MHC(Major histocompatibility complex) molecules.
Answer - c. T cells must recognize self MHC in order to recognize the antigen.

answer all the questions answering one question is not helpful 1. A helper T cell is capable of helping another cell because it expresses a protein on its surface that binds to a different protein on the surface of the cell being helped. What are these proteins (on the T cell, and on the cell being helped)? CD28, and B7 TNF, and TNFR Class I MHC, and TCR CD40L, and CD40 CTLA-4, and B7 2. Helper T cells are restricted...

Question 5 (2 points) Which is the most appropriate sequence of events in B cell signaling? Question 5 options: A) Antigen binds BCR, intracellular receptor kinases (such as Fyn, Lyn or Blk) are activated, Syk is recruited to ITAMs on Igα/Igβ. B) Antigen binds BCR, Syk is recruited to ITAMs on Igα/Igβ. intracellular receptor kinases (such as Fyn, Lyn or Blk ) are activated, C) Syk becomes activated, the BCR can now bind an antigen, and intracellular kinases are activated....
