Because of apoptosis, a) internal factors of the cell that transfer phosphate groups from one molecule to another in order to increase the energy of the receiving molecule b) proteins attach to receptors in the cell membrane to initiate cell division c) skin cells that form the embryonic webbing between chimpanzee fingers are destroyed d) cancer cells break away from a tumor and spread to other parts of the body

Imagine a self-reactive t cell that has not undergone clonal deletion in the thymus (that is to say, it has escaped central tolerance). if it encounters self antigen in the absence of an infection or inflammation, what will happen to this self-reactive t cell? (select two answers) (a) the t cell undergoes clonal expansion. (b) the t cell gains effector functions. (c) the t cell undergoes apoptosis. (d) the t cell becomes activated. (e) the t cell becomes anergic.
