    Q. What is the definition of  Selective Permeability?
    answer choices
    The movement of materials across the cell membrane that requires NO ENERGY from the cell.
    The movement of materials through (or across) the cell membrane
    The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

    Q. In the given scenario what will happen to the organism: salt is poured onto eggplant.
    answer choices
    Water will move out of the eggplant cells and the cells will shrink.
    Water will move out of the eggplant cells and the cells will swell.
    Water will move into the eggplant cells and the cells will swell.
  • Question 14
    30 seconds
    Q. In the given scenario what will happen?  An egg is placed in pure water for 48 hours.
    answer choices
    The egg will gain water and swell.
    Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
