HELP: (pls don't copy and paste from an article, it makes it obvious) Explain how mercury found in an aquatic environment can accumulate in biomagnification, and explain how limiting consumption of large predatory fish, such as swordfish, may be necessary for individuals trying to avoid high mercury concentrations.

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.
