the following statement true or false? Give an explanation for your answer.“Infection by a bacteriophage results in certain species of bacteria becoming pathogenic.”

The statement is true. Bacteriophages, also known as phages, are viruses that infect bacteria. Some bacteriophages are known to carry genes for bacterial toxins. When these phages infect bacteria, they can introduce these toxin genes into the bacterial DNA, transforming the bacteria into a pathogenic strain. This process is known as lysogenic conversion. Therefore, infection by a bacteriophage can indeed result in certain species of bacteria becoming pathogenic.
