Bacteria are growing in a liquid growth medium.There were 300,000 cells per milliliter during aninitial observation. The number of cells per milliliterdoubles every 3 hours. How many cells per milliliterwill there be 15 hours after the initial observation?A) 1,500,000B) 2,400,000C) 4,500,000D) 9,600,000

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

Bacteria are growing in a culture, and their number is increasing at the rate of 7% per hour. Initially, 500 bacteria are present.Determine an equation that gives the number, 𝑁, of bacteria present after 𝑡 hours.

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.

5 x 104 cells of Bacillus cereus were inoculated into fresh sterile nutrient medium and incubated at 30oC. After 2 hour lag phase, cells grew exponentially with a generation time of 30 minutes. How many cells would be present after 8 hours incubation? The growth of the bacterium in log phase can be expressed by the following equations: N1 = N0 2n & g = (T1 – T0) / n Where n = number of generations, N0 = initial number of cells at a particular time (T0), N1 = final number of cells at a particular time (T1), and g = generation time Group of answer choices 1.28 x 107 cells/ml 4.10 x 107 cells/ml 2.05 x 108 cells/ml 3.28 x 109 cells/ml 5.24 x 1010 cells/ml

A student adds 5 bacterial cells to a test tube containing fresh medium and incubates it for 3 hours at 37°C.  The bacterial population shows an initial lag phase of 20 minutes followed thereafter by a growth phase with a doubling time of 40 minutes.  Given this, what is the approximate number of bacterial cells present at the end of the incubation period?  (Note:  Assume unrestricted growth during incubation.)A.20 cellsB.40 cellsC.80 cellsD.160 cells
