Q.
Consider a population of 10 million cells. Given the per-capita birth rate of 0.002 (per unit time) and the percapita death rate of 0.002 (per unit time), the expected number of cells after 10 generations is ____.
A) 100 million
B) 1 million
C) 5 million
D) 10 million
Explanation
[Solution from source] r = b − d = 0.002 − 0.002 = 0, so the population neither grows nor declines and stays at 10 million. Answer (4).
