Answer:
D: 4.6 x ![10^{9}](https://tex.z-dn.net/?f=10%5E%7B9%7D)
Explanation:
4.6 x 10^{9} = 4,600,000,000
Earth is approximately, 4.6 billion = 4,600,000,000 = 4.6 x 10^{9}
<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is ![3.71\times 10^{6}cells](https://tex.z-dn.net/?f=3.71%5Ctimes%2010%5E%7B6%7Dcells)
<u>Explanation:</u>
We are given:
Proteus vulgaris divides and doubles every 28 minutes
Total time given = 6 hours = 360 min (Conversion factor: 1 hr = 60 min)
Number of times Proteus vulgaris doubles in 6 hours = ![\frac{360min}{28min}=12.857times](https://tex.z-dn.net/?f=%5Cfrac%7B360min%7D%7B28min%7D%3D12.857times)
Calculating the number of bacteria after 6 hours under ideal conditions:
We are given:
Initial population = 500 cells
Number of times it doubles = 12.857 times
Final Proteus vulgaris population = ![500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells](https://tex.z-dn.net/?f=500%5Ctimes%202%5E%7B12.857%7D%3D3709476.8%3D3.71%5Ctimes%2010%5E%7B6%7Dcells)
Hence, the final population of Proteus vulgaris after 6 hours is ![3.71\times 10^{6}cells](https://tex.z-dn.net/?f=3.71%5Ctimes%2010%5E%7B6%7Dcells)
Firstly, if you can't avoid it, you need to evade the area, or otherwise hide, don't find anyway near it. Don't let it through any of yourself.
