To determine the correct response regarding the trend observed in the number of bubbles produced during Trial 1 over the 10-minute period, I would need to see the actual data from the table you mentioned. However, since I do not have access to that data, I can't analyze it directly.
If you could provide me with the specific numbers of bubbles produced at various times during Trial 1, I would be able to help you identify the trend accurately. Please share the data, and I'll assist you further!
