You calculated the generation time of a strain of Pseudomonas aeruginosa as 40 minutes. How long would it take (in hours) for three generations to grow?ANSWER120 hours3 hours2 hours0.21667 hrs (13 minutes)

Exactly 200 bacteria are inoculated into fresh sterile growth medium at 9am and maintained at an optimum incubation temperature throughout the day. If the bacteria had a generation time of 30 minutes and there was a 1 hour lag period, how many generations will then take place by 3pm? The growth of the bacterium in log phase can be expressed by the following equations: Nt = N0 2n & g = (T – T0) / n Where n = number of generations, N0 = initial number of cells at a particular time (T0), Nt = final number of cells at a particular time (T), and g = generation time Group of answer choices 8 10 12 20 24

Suppose it takes 6 hours for a certain strain of bacteria to reproduce by dividing in half. If 40 bacteria are present to begin with, the total number present after 𝑥 days is𝑓⁡(𝑥)=40⋅16𝑥.Find the total number present after 1, 2, and 3 days.There will be bacteria present after 1 day, after 2 days and after 3 days.

A bacteria culture initially contains 100 cells and grows at a rate proportional to its size. After an hour the population has increased to 420.(a) Find an expression for the number of bacteria after t hours.P(t) = 100·4.2t (b) Find the number of bacteria after 4 hours. (Round your answer to the nearest whole number.)P(4) = bacteria(c) Find the rate of growth after 4 hours. (Round your answer to the nearest whole number.)P'(4) = bacteria per hour(d) When will the population reach 10,000? (Round your answer to one decimal place.)t = hr

You are growing bacteria in the lab and have added a drug that stops the bacteria from growing and kills them at an hourly rate of 0.8 per capita. What is the mean lifetime of a bacterium in this population?Group of answer choices8 hours1.25 hours0.2 hours0.8 hours

A bacteria culture P grows according to dPdt =kP. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions.1. What is the relative growth rate?Answer: k= 2. What was the initial size of the culture?Answer: P0= 3. Find an expression for the number of bacteria after t hours.Answer: P(t)= 4. When will the population reach 1000000?Answer (in hours): t=
