Answer: Arithmetic growth.
- A Arithmetic growth
- B Geometric growth
- C Exponential growth
- D Logarithmic growth
Correct answer: A. Arithmetic growth
Explanation: In arithmetic growth only one product of mitosis keeps dividing, so cell number rises linearly with time.
Geometric growth (where both daughter cells keep dividing) produces this classic S-shaped curve: a slow lag phase, a rapid exponential phase, and a levelling-off stationary phase as nutrients or space become limiting - the same fundamental pattern seen in population growth.
