Answer 3

Calculation of Bacterial Growth

To calculate the number of bacteria after 5 seconds, we need to consider that the bacteria divide into 3 parts every second. If we start with one bacterium in a test tube, we can calculate the number of bacteria after 5 seconds by multiplying the initial number of bacteria by 3 raised to the power of 5 (since there are 5 seconds).

Let's calculate it step by step:

1. Start with 1 bacterium. 2. After 1 second, the bacterium divides into 3 parts, resulting in 3 bacteria. 3. After 2 seconds, each of the 3 bacteria divides into 3 parts, resulting in 9 bacteria. 4. After 3 seconds, each of the 9 bacteria divides into 3 parts, resulting in 27 bacteria. 5. After 4 seconds, each of the 27 bacteria divides into 3 parts, resulting in 81 bacteria. 6. After 5 seconds, each of the 81 bacteria divides into 3 parts, resulting in 243 bacteria.

Therefore, the correct answer is 243 bacteria (A).
