हिन्दीConsider a population of 10 million cells. Given the per-capita birth rate of 0.002 (per unit time) and the per-capita death rate of 0.002 (per unit time), the expected number of cells after 10 generations is ____________.
Correct answer · Option 3
10 million
Explanation
Since per-capita birth rate equals per-capita death rate (b = d), the intrinsic rate of natural increase (r = b - d) is zero. Therefore, population size remains constant at 10 million.
