Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment and are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Answer:
TCR
Explanation:
Helper T cells are the CD4T cells that are present in the inactive form. These cells have receptors for antigens on their surface. These antigen receptors are called T-cell receptors (TCRs). The function of TCR is to recognize and bind to specific foreign antigen fragments that are presented in antigen–MHC complexes. Different helper T cells have their unique TCRs to recognize a specific antigen–MHC complex. The CD4 proteins of helper T cells also interact with the MHC antigens and help maintain the TCR–MHC coupling.
