    Hairlike projections used by some bacteria to propel themselves about are called ____.

    • Flagella

    • Cilia

    • Pediculosis

    • Both a and b

    Correct Answer
    A. Both a and b
    Explanation
    Both flagella and cilia are hairlike projections used by some bacteria to propel themselves about. Flagella are long, whip-like structures that rotate in a propeller-like motion, allowing bacteria to move in a straight line. Cilia, on the other hand, are shorter and more numerous, covering the entire surface of the bacterium and beating in a coordinated manner, allowing the bacteria to move in a wavelike motion. Therefore, the correct answer is both a and b, as both flagella and cilia serve as means of bacterial locomotion.
