Question 1
A biologist starts with 250 cells. After 3 hours, the culture has increased to 40,000 cells. Calculate how many generations occurred and what is the specific growth rate (μ).
💡 Hint: Use log calculations for determining generations and remember to convert time appropriately.
Question 2
If a bacteria doubles every 15 minutes, how many cells would result from 200 initial cells after 2 hours? Calculate the number of cells and explain the steps.
💡 Hint: Calculate the total time in consistent units to determine how many doubling times fit into 2 hours.
