the concentration of salt is higher inside a cell than outside the cell. the concentration of water inside the cell is lower than it is outside. salt cannot pass through the cell membrane.
what will happen to the concentrations of water and salt?
a.
water will move into the cell through diffusion. the salt concentration will be greater inside than outside.
b.
water will move out of the cell through diffusion. the salt concentration will be less inside than outside.
c.
water will move into the cell through osmosis. the salt and water concentrations will become similar inside and outside the cell.
d.
water will move out of the cell through osmosis. the salt and water concentrations will become similar inside and outside the cell.

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.
