Reproduction can be either asexual or sexual. a. using a specific example, describe how organisms can reproduce asexually. discuss two evolutionary advantages of asexual reproduction. b. identify three ways that sexual reproduction increases genetic variability. for each, explain how it increases genetic diversity among the offspring.

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.
