Because the separation of the sister chromatids during anaphase is an irreversible step, the cycle will not proceed until the kinetochores of each pair of sister chromatids are firmly anchored to spindle fibers arising from opposite poles of the cell.

When cilia are present, there can be many of them, extending along the entire surface of the plasma membrane.

Therefore, the pK a is a quantitative measure of how easily or how readily the acid gives up its proton [H + ] in solution and thus a measure of the "strength" of the acid.
