Shown below is a culture of bacteria growing on an agar plate.The diameter of one of the colonies is 3.5 mm.Calculate its cross-sectional area.____ mm2Write your answer to 1 decimal place.

In the viable plate count method, a measured sample of a culture is evenly spread across an agar surface and incubated. Each _____ represents one _____ from the sample. A. cell, cell B. cell, colony C. colony, cell D. species, colony E. generation, cell Question 29 options:

The bacterial shape of the cells in Figure 1.1 would best be described as Group of answer choicesbacillus.spiral.ovoid.columnar.coccus.

A sterile agar plate, I, is streaked with a pure culture of bacteria by means of aseptic techniques. Paper discs treated with the antibiotics Aureomycin (A) and penicillin (P) are placed at opposite sides of the plate, as shown in the diagram above. The plate is examined after a 24-hour incubation period, and a clear ring is discovered around disc A, but not around disc P. Within the clear ring around disc A, a single bacterial colony with physical characteristics like those of the pure culture is observed. A second sterile agar plate, II, is then streaked with this single colony and also incubated with antibiotics.

When a bacterial cell is placed in a solution with higher solvent concentration and low solute concentration, relative to it's cellular contents, this osmotic possibility is _______Group of answer choiceshypotonichypertonicisotonic
