Mitosis &amp; Meiosis: Thinking Scientifically
REY [17]

Answer:

65536 cells

Explanation:

starting from 1 cell at zero minutes  there will be 1 (2^0) cell; 2^0 = 1

after 15 minutes                    there will be 2 (2^1) cells

after another 15 minutes ( 30 min)        there will be 4 ( 2²) cells

after another 15 minutes ( 45 min)         there will be 8 (2³) cells

after n number of 15 minutes                  there will be (2^n) cells

calculate number of 15 minutes in 4 hours

4 hours = 4 × 60 minutes

number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16

using the formula above and substitute 16 for n in the formula

Number of cells = 2 ^n = 2^16 = 65536 cells
