Answer:
1) By 11:30pm
2) Shortly before midnight (few minutes to 12:00am)
Explanation:
Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:
I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour
II) Split 1 hour into two (60minutes makes 1 hour)
I hour/2 = 30 minutes
Definitely, the bottle will be half filled by 11:30pm
2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out
