This exercise uses the population growth model. The count in a culture of bacteria was 400 after 2 hours and 25,600 after 6 hours. (a) What is the relative rate of growth of the bacteria population? Express your answer as a percentage. (Round your answer to the nearest whole number.) 104 % (b) What was the initial size of the culture? (Round your answer to the nearest whole number.) 200 x bacteria (c) Find a function that models the number...
Growth of Bacteria The growth rate of Escherichia coli, a common bacterium found in the human intestine, is proportional to its size. Under ideal laboratory conditions, when this bacterium is grown in a nutrient broth medium, the number of cells in a culture doubles approximately every 20 min. (a) If the initial population is 20, determine the function Q(t) that expresses the growth of the number of cells of this bacterium as a function of time t (in minutes). (b) How long would...
Given the same initial bacterial colony of 1000 and an initial exponential growth rate of 30%, and a carrying capacity of 10 000 bacteria, what is the logistic growth population 10 hours after the start? (Round your answer to the nearest whole number) A. 6619 B. 5910 C. 7281 D. 10000
E. coli has a doubling time of 20 minutes, if a piece of meat is contaminated with 1 E. coli cell how many cell would it contain after 12 hours? What about 24 hours?
In the year 2000, the population of a certain country was 276 million with an estimated growth rate of 0.5% per year a. Based on these figures, find the doubling time and project the population in 2120 b Suppose the actual growth rates are ust 0.2 percentage points lower and higher than 0.5% per year 0.3% and 0.7%). What are the resulting doubling times and projected 2120 population? a. Let y(t) be the population of the country, in millions, t...
please answer both questions and show necessary work 4. If Bacterium X has a generation time of 60 minutes and 10 Bacteria X cells are inoculated into broth, how many hours will it be before there are 10° Bacteria Y colls in the broth culture? You MUST SHOW YOUR WORK to get credit. (2 % pts. total) 5. Using the graph below, draw the expected growth curve for a bacterial microorganism that spends 60 minutes in the lag phase, undergoes...
Modeling Exponential Growth and Decay A biologist recorded a count of 360 bacteria present in a culture after 7 minutes and 1200 bacteria present after 20 minutes. a. To the nearest whole number, what was the initial population in the culture? The initial population was around bacteria. b. Rounding to four decimal places, write an exponential equation representing this situation. B(t) = c. To the nearest minute, how long did it take the population to double? The doubling time of...
