Low temperature is the most responsible factor for lack of plants in polar regions.

<u>Explanation:</u>

Due to extreme low temperatures in the polar areas, the soil in this area is completely frozen. In this case, the roots of the plants do not grow very deep. Therefore, there is little or no thick vegetation in this region.

The polar climate is a place where the available temperature is usually lower than cold, icy, snowy and does not get direct sunlight.  The Polar Regions, also known as frigid areas. These are planet regions that cover the geographical poles (north - Arctic and south - Antarctic) and are located in the polar Circle.

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
