Pre-Lab Questions 1. What determines if a bacterial cell is Gram-positive or Gram-negative? (5 points) Amount and location of the peptidoglycan molecule in the prokaryotic cell wall determines whether a bacterial cell is Gram-positive or Gram-negative. 2. In this lab, both viruses and prions were introduced as acellular organisms. Do some research and describe […]

NEGATIVE STAINING Negative staining provides a more detailed assessment of a microbe’s morphology and helps prevent any distortion of the mi- crobe’s ultrastructure by the staining procedure. It also makes the outline of the cells highly visible. Nigrosin and bacterial cells are negatively charged. Therefore, negative staining works because like charges repel each other, preventing
What type of graph would be appropriate for this data set? Why? A line graph is most appropriate because it can best display the relationship between the variables. 7. Graph the data from Table 4: Water Quality vs. Fish Population (found at the beginning of this exercise). 18 8. Interpret the data from

What would be your control? Possible Control: Aquarium with no fish. Measure the dissolved oxygen level in a fish tank at normal room conditions, and repeat this measurement every time you make an observation of the number of fish. [Use only one type of fish for your experiment, and control other variables such as light,
