Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
Explanation:
Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.

Mutations can be categorized based on the kind of effect they have on an organism. Blue eyes in humans are a result of a mutation in the OCA2 gene, which controls the production of pigment melanin in the iris.
This mutation is an example of a neutral mutation. Such mutations have no effect on an organism’s survival.
