Where the phages and bacteria streaks intersect, this is going to form a clear halo zone called plaque.
It is because bacteriphage who infects bacteria or literally eats it will result into a clear zone on the bacterial lawn if it is present with some anti-bacterial factor, like bacteriphage. Bacteriophases digest the bacteria in its vicinity and you can see plaques indicating the inhibition of dissolution of bacterial cells.
Hope it helps, Good luck !!!!!

2- choose the correct option You streak an agar plate, using an inoculum from a tube of a broth culture of E. coli. After 1 day of incubation, you see confluent growth covering the whole surface of the plate. Which of the following errors would NOT explain this result? You put the plate in the fridge instead of the incubator You forgot to flame the loop between sections of the plate You picked additional culture up from the plate after...

what do you expect to happen in the long
Suppose that the price of corn, a crop produced in a perfectly (or purely) competitive industry, increased 208 % last year as demand for corn based ethanol fuel increased. What do you expect to happen in the long run for the corn industry given this recent success? Suppose the firms in the market for bacon, also a perfectly (or purely) competitive industry, experienced losses last quarter the to people becoming increasingly...
