At ASU graduation during the festivities, your great aunt brings a potato salad to share. Your auntie places the potato salad on a picnic table in the hot sun at 1:00 pm – where it continues to sit all day. This potato salad is starting to look funny and it smells quite bad! With your special training in bacterial population ecology, you estimate the population size of E. coli bacteria in this dish to be 300,000 cells at 4:00 pm and 600,000 cells at 5:00 pm. Able to replicate in one hour, how many bacteria will be there by 6:00 pm? (One growth cycle). Select only ONE answer choice. Hint: because this is a population has been growing all day, it may be running out of resources – hence the logistic growth equation is probably appropriate. We will assume a carrying capacity of 2,000,000 cells.
