A biology lab cultures stem cells. Each day, the population increases by 15%. If the initial count is 800 cells, how many cells are present at the end of day 5?

**Why the Future of Stem Cell Labs Grows Daily — and How Many Cells Rise in Just 5 Days** Every day, a single stem cell lab culture expands by 15%, turning steady science into a quiet daily growth story — one that’s reshaping conversations in both research and public dialogue. With cells multiplying not like plants or bacteria, but with precise mathematical rhythm, this process holds real implications for medicine, biotech innovation, and how we approach regenerative healing. Today, 800 stem cells kick off a prediction: what becomes of that number exactly by day 5, and why does it matter? **The Science Behind Daily Growth**
A biology lab culturing stem cells works with controlled environments where conditions maximize viability and growth. Stem cells replicate asexually — each cell divides into two, often maintaining stemness under ideal lab settings. When increasing by 15% per day, scientists apply consistent parameters — temperature, nutrients, and treatments — to sustain exponential progression. This pattern mirrors real-world trends in synthetic biology, where precision drives predictable output over time. Day 5 captures how carefully managed biology translates into measurable cell count growth, not magic, but measurable biology. **How Does 800 Cells Multiply Over 5 Days?**
Calculating daily compound growth starts with understanding the formula: final count = initial count × (1 + rate)^days. For a 15% daily increase, that’s multiplying by 1.15 each day.
