Question 1
The formula for calculating the number of cells during exponential growth is:
- N_t = N_0 × 2^n
- N_t = N_0 + n
- N_t = N_0 / 2^n
💡 Hint: Focus on how cells multiply over time.
Question 2
Is the generation time crucial for predicting microbial growth dynamics?
- True
- False
💡 Hint: Think about its significance in fermentation and bioproduction.
