How can a cell, killed by heat in order to render it harmless, somehow still act to transform a second strain of bacterium from a noninfectious form into a disease carrier (i.e., a pathogen)?

    The second (noninfectious) strain of bacterium was changed into a disease carrier (i.e., pathogen) by something from the heat-killed cell.
    The second (noninfectious) strain spontaneously mutated into a deadly pathogen.
    The heat-killed cell wasnt really dead.
    Both the second and third answers above are correct.
