Solution please
Step by step
Solved in 2 steps
- In a viable plate count, each _________ represents a _________fromthe sample population.a. cell, colony b. colony, cell c. hour, generation d. cell, generationDefine the following terms that are commonly used describe colonies: 1. Form - 2. Elevation - 3. Margin -How would you record your observation of a plate containing 305 colonies?A plate with 15 colonies?
- One of the following is INCORRECT about Spread plate a-Allow aerobic bacteria to grow b-The sample is spread on agar surface by a sterile glass spreader c-Only Surface colonies emerge after incubation d-Exclude Heat-sensitive bacteria.In General, the most suitable description for the origin of each colony formed on the surface of a solid medium is: a-Cluster of cells b-Colony forming unit c-Pair of cells d-Single cellAs revealed by different colony types, would there be a different species of bacteria/microorganism that can be found in any given environment?
- propose a hypothesis regarding the organisms (staphylococcus, escherichia, pseudomonas, and bacillus) that will be resistant to the most disinfectants, and why? if the hypothesis is supported, what specific experimental results will be observed? what would be the independent and dependent variable? zone size, disinfectant type, colony countHi, I have the answer for A, but I am not sure for B and C. For: A, I believe B. B, I think its low colony forming unit count C, I am not sure about it.What event is required but not sufficient to cause an infectiousdisease?
- What factors might give rise to variation in the sizes of the colonies?Complete the colony morphology for the colonies pictured above: 1. Form - 2. Elevation - 3. Margin - 4. Surface - 5. Chromogenesis -As shown in this diagram, you perform a ten-fold serial dilution of a culture to determine the number of colony forming units (CFU) per mL it contains. You do a plate count with these growth results (no. of colonies for each dilution): 1:10 too many to count; 1:100 too many to count; 1:1,000 312; 1:10,000 38; 1:100,000 no growth. The number of CFU per mL in the original culture was: A. 38 B. 380,000 C. 38,000 D. None of the other four answers (Correct answer not given) E. 10,000
