Final answer:
The population of the yeast cell after 5 hours cannot be determined.
Step-by-step explanation:
The population of the yeast cell can be calculated using the formula for exponential growth: P = P0 * (1 + r)^t, where P is the final population, P0 is the initial population, r is the relative growth rate, and t is the time in hours. In this case, the initial population is not given, so we cannot determine the exact population after 5 hours.
Therefore, the correct answer is option 1) Cannot be determined.
