The colonies on the petri dish arose from A) cells that where live in the liquid culture
because colonies on the petri dish are formed only when the cells are alive
And inoculating of petri dish is the method to check whether the cells are alive or not on the liquid medium.
Add Answer to:
When a petri dish was inoculated from liquid culture, the colony on the petri dish arose...

The shape of a colony of bacteria on a Petri dish is circular. Find the approximate increase in its area if its radius increases from 10 mm to 16 mm. The estimated change in area is mm2 (Type an exact answer in terms of t.) Sociologists have found that crime rates are influenced by temperature. In a town of 100,000 people, the crime rate has been approximated as C = (T-60)2 + 100, where C is the number of crimes...

Q4.14. The image below is from the video showing bacteria growing across a giant Petri dish with zones of increasing antibiotic concentration. The nodes (dots) represent places where researchers sampled, and color changes correspond to mutations for resistance in bacterial strains. Which of the following is demonstrated by the research results? Mutations conferring antibiotic resistance happen because bacteria need them in order to survive. O Antibiotic resistance can evolve independently multiple times during a single experiment. Individual bacterial cells can...

You are studying neurons in the lab by growing them in culture (in a petri dish outside the body). You grow them in an incubator at 37 degrees C. With this experimental setup, you can easily change the extracellular ion concentrations by switching the cell culture medium (the fluid that surrounds the cells).Intracellular concentrationMedium 1 (extracellular concentration)Medium 2 (extracellular concentration)K+140 mM4.5 mM50 mMNa+10 mM135 mM100 mMCl-12 mM125 mM120 mMa.If you switch from Medium 1 to Medium 2, will the intracellular...

gRNA plasmid?
Plate counting Last week you transformed the PMD2 plasmid that contains the ORNA sequence. The yeast cells were selected on a YNB + histidine + methionine plate in order to make sure that only the cells that contain the plasmid grow and give a colony. Simply count the number of colonies that grew...

Materials and methods We need to have all our tubes already sterilized, and the petri dish that we are going to use in this experiment. Our dishes must be labelled on the bottom part and the tubes in one side with our initial names, bench number and the number given to the bacteria. Take inoculum tubes, the sterilized tubes, and the plates near to our non-dominant hand. Lift the Bunsen burner: we need to attach the hose of the Bunsen...

PART IV: We can model the equilibrium process using BB's to represent molecules and petri dishes to separate "reactant molecules" from "product molecules." 1) Consider the simple equilibrium A = B For this BI Кф [A] and we'll assign a value to Koq of 8. Keq = 8.0 Get 2 petri dishes and place 27 BB's in one of them. These represent 27 "A" molecules, while the empty dish shows that there are "B" molecules. no [B] value is 8...

5. A slide mount of a fungal specimen is prepared. A slide and coverslip are flame-sterilized. The coverslip is prepared and set on two hardened strips of sterile paraffin on the slide. Molten sterile Sabouraud dextrose agar is cooled to near-solidification point, then inoculated with mold and streamed under the coverslip with a sterile Pasteur pipette. Once the agar has solidified, the slide is placed into a sterile Petri dish and allowed to incubate at room temperature for four days...

6. Transposon mutagenesis was performed to identify genes that are involved in the biosynthesis of theA amino acid alanine. A wildtype culture of E. coli was infected with a defective phage carrying Tn10 A and the culture was plated on LB-tet media to obtain tet-resistant colony forming units. (LB is a rich growth media for E. coli and contains all amino acids required for bacterial growth) Individual CFU were then transferred to a multiwell plate containing liquid LB-tet media and...
