Transcribed Image Text:Gregory accidentally introduced one bacterial cell into the pasta salad while preparing food
for the class picnic. The salad sat at room temperature for two hours before the picnic.
QUESTION: How many bacterial cells are in the salad after that time, assuming the generation
time is 30 minutes?
1. Use the formula to calculate the size of a bacterial population over time (Nf): N₁ = (N¡) 2n
。 N₁ = Total number of cells in the population at some point in the growth phase
• Ni = Starting number of cells
Ο
n (exponent) = generation number
。 2n = Number of cells in that generation
