Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins.

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 $3.71\times 10^{6}cells$
