While examining the cell culture of certain bacterial species under a microscope, the researcher notes that all cells do not look the same. The researcher, therefore, concludes that the cell culture is contaminated in the sense that it contains different bacterial species. Is it possible that the researcher concluded incorrectly? (and please explain why)
a. yes or b. no
Homework Answers
Yes it can be possible that the researcher concluded incorrectly because it is possible for one bacterial species only to show different shapes.Bacterial morphology is affected by a number of factors and their combination like nutrient access,cell division,attachment,dispersal,predation ,motility etc.So it may be possible that different bacterial cells in the culture must be getting affected by differences in these factors and therefore they have different shapes.

A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 1.10 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 4.00 μm/s , with an uncertainty in the velocity of 1.00 % . E. coli bacterial cells are around 1 μm ( 10−6 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just...

You isolate individual bacterial plasmids from cells and run a gel electrophoresis. You know that there are three possible forms the bacteria DNA can take: superhelical/supercoiled (form1), nicked/open circle/no supercoiling (form II), and linear (form III). a) List the forms from most compact to least compact: b) All three forms have...
