A researcher is studying a colony of bacteria that doubles every 3 hours. If the initial population is 500 bacteria, how many bacteria will there be after 15 hours?

--- ### How A Researcher Tracking Bacterial Growth With a 3-Hour Doubling Time Reaches 16,000 Cells After 15 Hours In the fast-evolving world of microbiology, understanding how microbes multiply under controlled conditions reveals key insights into infection dynamics, biotech applications, and medical research. Right now, audiences across the U.S. are drawn to this topic—driven by growing interest in microbiome science, infection control, and the powerful implications of exponential growth in real-world settings. When a scientist studies a bacterial colony that doubles every 3 hours, starting with just 500 cells, the progression offers a clear, predictable pattern: each doubling cycles through measurable growth—turning 500 into 1,000, then 2,000, and so on. This isn’t science fiction—it’s a measurable, predictable process that research labs track closely to anticipate microbial behavior in clinical or industrial environments.
