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.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.

the statements that apply here about binary star system are

"have stars that might appear to wobble"

"often have one star that is brighter than other"

a binary star is a star system consisting of two stars revolving around their common barycenter. systems of two or more stars are called multiple star systems.
