Proteus vulgaris has a doubling time of roughly 28 minutes. If an initial population of 500 cells is allowed to grow for 6 hours

romanna [79]

<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

<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 = $\frac{360min}{28min}=12.857times$

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 = $500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells$

Hence, the final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

Describe relationship between observation and scientific theory

SOVA2 [1]

37. Observation and scientific theory are both related. Because it needs hypothesis and experiment to be able to have an actual data to show. For example: If you want to know how a monggo seeds grow on a wet cotton. Then you should be preparing the needed things and perform the experiment. You need to observe to be able to get the scientific theory of how this experiment works. That’s how observation and scientific theory is related. They will always be together in science.
