A

Key Concept

Exponential Growth in Cell Culture

Explanation

The cell density in a culture that doubles every hour can be calculated using the formula $N = N_0 \times 2^t$, where $N$ is the final cell density, $N_0$ is the initial cell density, and $t$ is the time in hours. After 3 hours, the cell density would be $4 \times 10^4 \times 2^3 = 4 \times 10^4 \times 8 = 3.2 \times 10$
