If a scientist carried out a growth experiment on a prokaryote in media without a nitrogen source you would expect:Question 3Answera.Not enough information to determineb.Normal growthc.No growthd.Intermediate growth

When preparing growth media for Enterococcus durans, one must add amino acids, vitamins, and other growth factors in order for the organism to grow properly. This organism is said to be __________.ANSWERnitrogen fixingphototrophicautotrophicfastidious

How would you differentiate a normal growth pattern from a bacterial growth pattern?

Which of the following is an example of a metabolic activity that could be used to measure microbial growth?Group of answer choicesstandard plate countMPNdirect microscopic countglucose consumptionturbidity

You inoculated a pure culture of unknown bacteria into a tube containing thioglycollate medium to study their metabolic relationship with oxygen. The culture was incubated for an appropriate length of time at the optimal growth temperature of the organism. When you examined the culture, you observed that although the organism grew throughout the medium, the growth was denser at the surface. What would you conclude about the oxygen requirements for this unknown species?ANSWERThe unknown is an obligate anaerobe.The unknown is an obligate aerobe.The unknown is a microaerophile.The unknown is a facultative anaerobe.
