Final answer:
The rate of change in the number of fruit flies per hour in Vance's experiment from 1 pm to 4 pm is -90.67 flies per hour.
Step-by-step explanation:
The question posed is related to rate of change in the number of fruit flies per hour during Vance's experiment, which falls under the subject of Biology, specifically within the domain of genetics and population studies. The rate of change represents how much one quantity changes in relation to another quantity. In this case, we want to find the rate of change in the number of fruit flies per hour from 1 pm to 4 pm in Vance's experiment.
To calculate the rate of change, we can use the formula:
Rate of change = (change in number of fruit flies)/(change in time)
In this case, the change in number of fruit flies is -90.67 (assuming a decrease in the number of fruit flies), and the change in time is 3 hours. So the rate of change would be:
Rate of change = -90.67 flies per hour
Therefore, option C represents the rate of change in the number of fruit flies per hour in Vance's experiment from 1 pm to 4 pm.
