  1. jeez! this is just too easy! there's something called google if you didn't know.

    LOOK IT UP! ARE YOU IN 6TH GRADE?


  2. Manipulated variable is what you change in the experiment

    Controlled variable is what stays the same in the experiment. It's controlled

    Responding variable is what the outcome is in your experiment

    I think that would be either A or B

  3. Controlled would be like how fast you run and how long (distance) you run

    Responding variable would be how long you wait after the run before you count your pulse

    Manipulated varible would be how long (time) u run.

    Im not 100% sure about these
