Which describes the benefit of using Bdellovibrio bacteria to control microbes? Multiple Choice Bdellovibrio bacteria harbor a bacteriophage that can lysis (kill) pathogens such as Salmonella spp., Shigella spp., and E. coli. Bdellovibrio bacteria stimulate the immune system to more accurately detect and destroy pathogens such as Salmonella spp., Shigella spp., and E. coli. Bdellovibrio bacteria are predators of Gram-negative pathogens such as Salmonella spp., Shigella spp., and E. coli. Bdellovibrio bacteria release toxins (i. e., antibiotics) to kill off or inhibit pathogens such as Salmonella spp., Shigella spp., and E. coli.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
