       time: The time (in minutes) that the cells were sus-
             pended in the solution.

        cal: The amount of calcium uptake (nmoles/mg).

        The `calcium' data frame has 27 rows and 2 columns.

        Howard Grimes from the Botany Department, North Car-
        olina State University, conducted an experiment for
        biochemical analysis of intracellular storage and
        transport of calcium across plasma membrane.  Cells
        were suspended in a solution of radioactive calcium for
        a certain length of time and then the amount of
        radioactive calcium that was absorbed by the cells was
        measured.  The experiment was repeated independently
        with 9 different times of suspension each replicated 3
        times.
