question 16 of 25
a single staphylococcus aureus cell gets into a wound on someones foot. staphylococcus aureus is a bacterium that can cause infections in broken skin.
s. aureus divides by binary fission approximately once every 30 minutes. calculate the number of s. aureus cells in the wound after 30 minutes, one hour, and 12 hours.
after 30 minutes:
s. aureus cells
after one hour:
s. aureus cells
after 12 hours:
s. aureus cells

×10^y

Explanation:

Step1: Calculate after 30 minutes

Binary fission doubles cells. $1 \times 2 = 2$

Step2: Calculate after 1 hour

2 divisions: $2 \times 2 = 4$

Step3: Calculate after 12 hours

Number of divisions: $\frac{12 \times 60}{30} = 24$. Cells: $2^{24} = 16777216$

Answer:

2, 4, 16777216
