Which statements help explain this result? Check all that apply.The bottle was 1/2 full at 11:35 a.m. and doubled again after 5 minutes.The bottle was 1/4 full at 11:30 a.m. and doubled twice after 10 minutes.The bottle was 1/2 full at 11:35 a.m. and more bacteria were added to fill the bottle.Exponential growth involves a constant multiplicative rate of change.Exponential growth involves a constant additive rate of change.
Use the fact that the bacteria is doubling every five minutes. What fraction of the bottle was full at 11:20 a.m.?

The bacteria took 1 hour and 40 minutes to fill the initial bottle. Explain how it only took 10 minutes to fill 3 additional empty bottles.
Because the bacteria growth is exponential, the number of cells doubles at a constant rate. While it took a long time to reach the volume of one bottle starting from a single cell, once the bottle was full, all those cells doubled simultaneously. If the doubling time is 5 minutes, the one full bottle would produce enough cells to fill a second bottle in just 5 minutes. Then, those two full bottles would double again in the next 5 minutes, producing enough cells to fill two more bottles (for a total of four bottles) in only 10 minutes total.
At 10:05 a.m., there are 2 microscopic bacteria cells in the bottle. At 10:15 a.m., there are 8 cells in the bottle.
