4. You have a culture of yeast that is at a density of 8x107 cells/mL. You dilute the sample 1:10, then 1:1,000 again, and finally you dilute the sample an additional 1:5. You add0.1 mL of the final dilution to a spread plate. Assuming that most of the cells in the original culture were living, how many colony- forming units do you expect to count on your pour plate the next day?

The proteobacteria in the genus Pseudomonas are important spoilers of food. The rate at which food spoils is dependent on temperature. The data in the Figure show the relationship between the square root of the growth rate (how fast the population is growing per day; unitless) and the temperature of the culture. Does typical refrigeration (temperature lowered to 4C) appear sufficient to limit growth rate compared to room temperature (20C)?
Many of the first prokaryotes to be cultured in a scientific lab were human or animal pathogens. Why would these species he more readily cultured than non-pathogenic prokaryotes? Pathogenic prokaryotes are hardier than non-pathogenic prokaryotes Non-pathogenic prokaryotes require more supplements in their growth media Most of the necessary culture conditions could be inferred for pathogenic prokaryotes Pathogenic bacteria can grow as free bacteria, but non-pathogenic bacteria only grow as parts of large colonies.
Figure 13.6 Which of the following statements is true? a. Gram-positive bacteria have a single cell wall formed from peptidoglycan. b. Gram-positive bacteria have an outer membrane. c. The cell wall of Gram-negative bacteria is thick, and the cell wall of Gram-positive bacteria is thin. d. Gram-negative bacteria have a cell wall made of peptidoglycan, while Gram-positive bacteria have a cell wall made of phospholipids.
Prokaryotes stain as Gram-positive or Gram-negative because of differences in the_______. a. cell wall b. cytoplasm c. nucleus d. chromosome
Yeast is a facultative anaerobe. This means that alcohol fermentation takes place only if: the temperature is close to 37°C the atmosphere does not contain oxygen sugar is provided to the cells light is provided to the cells
What type of micrograph is shown below? Is the organism pictured prokaryotic or eukaryotic? How can you tell?
Which of these statements is true? An antibiotic is any substance produced by a organism that is antagonistic to the growth of prokaryotes An antibiotic is any substance produced by a prokaryote that is antagonistic to the growth of other viruses An antibiotic is any substance produced by a prokaryote that is antagonistic to the growth of eukaryotic cells An antibiotic is any substance produced by a prokaryote that prevents growth of the same prokaryote.
Which of the following is not a property of an endospore? a. resistant to boiling-must be autoclaved to be killed b. metabolically inactive c. can potentially survive millions of years d. provides a method to preserve bacterial DNA under harsh conditions e. is the portion of the bacterial cell that undergoes conjugation
Sterile normal saline is used in most surgical procedures as an irrigation solution. During certain surgical procedures, such as those for malignancy, the surgeon may request that sterile water be used for irrigation instead of saline following excision of the cancerous mass. Why is normal saline usually used in healthy tissues?
At the health center, a fecal sample was taken from a feverish student. Organisms with corkscrewlike flagella and no endomembranes but with cell walls that lack peptidoglycan were isolated as the cause for the illness. These organisms probably belong to the group: a. chlamydias. b. spirochetes. c. Euryarchacota. d. Cyanobacteria. e. Archaea.
