Step by step
Solved in 2 steps
- What type of growth is displayed in the graph?1. Draw and label the parts of the growth curve if it is exponentially growing and inoculated in the same nutritious medium under the same optimum conditions. Answer and draw this completely.Based on the growth curve, which ONE of the following best describes what would happen if sample of culture in the presence of drug B is inoculated onto drug-free growth medium? Select one: A. Growth present, but cell count increased by at least 99.9% of the original culture B. No growth after 24 hrs C. Growth at 24 hrs D. Not possible to predict because the culture could either be alive or dead E. Growth present, but cell count reduced by at least 99.9% of the original culture
- So is it fair to say that #1 treatment 1 has steady growth treatment 2 has stead growth treatment 3 has steady growth treatment 4 has very little growth treatment 5 has some growth treatment 6 steady growth #2 The carbon dioxide provided a good amount of growthExamine the following graph. Note that the growth rate increases slowly until the optimum is reached, andthen it declines steeply over higher temperatures. In other words, organisms tolerate a wider range oftemperatures below their optimal temperature than they do above the optimum. Explain this observation please explain the observationCalculate the growth rate and generation time of a culture that increases in the exponential phase from 5 x 102 to 1 x 108 cells in 12 hours.
- Please calculate E. coli generation time for each growth condition using slope method described in Week 5 on Brightspace and formulas provided. Be sure to express generation time either in,minutes or hours for all growth conditions. (You may use attached Excel file for data manipulations). Please compare growth condition and submit your recommendation to Matt. Be sure to elaborate on how and why nutrients and temperature play affect the growth rate. Suppose you want to calculate generation time of a neutrophile, but accidentally inoculated broth that has alkaline pH, what will happen to its generation time? Why?Indicate which of the following observations can be made when observing growth on nutrient agar. Check all that apply. please look at the attached imageexplain the liquid growth analysis process in your own words
- How can I answer following two question, that are about the growth curve above ^^Calculate doubling time (td) and specific growth rate (μ) by using logarithmic growth stage.The cell concentration measured in samples taken at certain intervals from a microorganism growth medium is given below. Calculate the doubling time and specific growth rate of this microorganism.
