Please find the answer below:

On EMB agar containing E.coli, what should the colony morphology be?

Answer: a. Shiny metallic green surface on colonies

Explanation: EMB agar is a differential microbiological medium. It inhibits the growth of the gram-positive bacteria and is used to indicate and distinguish the different organisms by different colours. For E.coli, on EMB agar, there is a characteristic green sheen

    E. coli cells were spread on two agar plates [one containing only agar (plate 1) and the second containing streptomycin (plate 2) which kills all cells except those that are resistant mutants]. Both plates were allowed to grow for several generations. Cells were collected from the agar plate WITHOUT streptomycin and spread again on a fresh agar plate containing streptomycin (plate 3). More mutants were observed on plate 3 than were observed on plate 2. The experiment demonstrates A. how...
