Answer:
12-14 october
Explanation:
The probable period of exposure is calculated as follows:
- Know  the range of the incubation period 
- Start counting back from the days of the first case by subtracting the first number of incubation period range
-  Count back the days from the last case by subtracting the last number of incubation period range. 
- This will give a range which will be the period of exposure.
From the question,
- Incubation period range 1-15
- Date of first case = october 15
- Therefore, first date of exposure = 15 -1 = 14
- Date of last case = 22
- Therefore, last date of exposure = 27 - 15 = 12
- Thus, the range is 12-14 october which is the probable period of exposure. 
 
        
             
        
        
        
Answer:
Mitosis
