A culture of bacteria grows in a petri dish, and its population is graphed over time. Which statement is true about the bacteria population?
1 Answer
Verified archiveThe correct statement is: “The bacteria population doubles every 5 hours.”
Explanation: In many bacterial cultures, especially when nutrients are abundant, the population can exhibit exponential growth, which means it doubles at regular intervals. If the experiment is set up in a way that allows for unchecked growth, this doubling every 5 hours is a common characteristic of bacterial growth in ideal conditions.
