Final answer:
The bacteria count at the end of two hours in the given experiment is 8000.
Step-by-step explanation:
To find the bacteria count at the end of two hours, we need to apply exponential growth.
The count of bacteria is increasing at a rate of 2% per hour.
This means that each hour the count doubles.
Starting with an initial count of 2000, after the first hour, the count will double to 4000.
After the second hour, the count will double again to 8000.
So, the bacteria count at the end of two hours is 8000.
