Lysogenic bacteriophages contribute to bacterial virulence because bacteriophages kill human cells. carry plasmids. kill the bacteria, causing release of endotoxins. produce toxins. give new gene sequences to the host bacteria.

give new gene sequences to the host bacteria.

Explanation:

Bacteriophages are viruses that infect bacteria. Viruses are the most numerous organisms on earth and play functions in the biotic component of virtually every ecosystem. They are distinct biological entities and the main feature of this group is the dependence on specific hosts for reproduction, hence known as obligate intracellular parasites. In the lysogenic cycle, phage nucleic acid recombines with that of the bacteria forming a prophage and replicates in the host cell from one generation to another without cell lysis. By doing this, the bacteriophages give new gene sequences to the host bacteria, contributing to bacterial virulence.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
