How do cocci and rods differ in morphology? Give an example of a bacteria with each morphology. correct answers Cocci are spherical or ovoid (ex: Streptococcus or Staphylococcus) while rods/bacillus are cylindrical/longer than it is wide (ex: Bacilli or Salmonella). Using a microscope, could you differentiate a coccus from a spirillum? A pathogen from a nonpathogen? correct answers Yes, a coccus is spherical while a spirillum is curved or spiral. No regarding the pathogens from nonpathogens. ...

A cotton fiber consists mainly of cellulose, whereas a potato tuber contains mainly starch. Cotton is tough, fibrous and virtually insoluble in water. The starch present in a potato tuber is neither tough nor fibrous and can be dispersed in hot water to form a turbid solution. Your friend says that this is because starch and cellulose are made of monomers with vastly different properties. You need to set your friend straight. How would you go about doing this? Cellulose and starch are both p...

How to measure antimicrobial activity? : Make a very dilute suspension of the pathogen in growth medium and aliquot equal volumes into a series of culture tubes. Add increasing concentrations of the antibiotic to the tubes, from ~1 μg/ml to ~1 mg/ml. Allow all cultures to grow overnight. The tube with the lowest concentration of antibiotic in which there was NO GROWTH of the bacteria represents the MIC. MIC: minimal inhibitory concentration lowest concentration of an agent that complet...
