<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is 
<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 = 
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 = 
Hence, the final population of Proteus vulgaris after 6 hours is 
 
        
             
        
        
        
Punnet square
Let's call black 'B' and white 'b'
Being intermediate, gray cats will have the alleles 'Bb'
Being recessive, white cats will have the alleles 'bb'
          <u>       Gray  </u>
          |<u>  </u>|<u>  B   |  b |</u>
White |b|<u>  Bb | bb|</u>
          |b|<u>  Bb | bb|
</u>
^Apologies for the awful drawing XD
Bb = Gray
bb = White
So the cats can have gray or white fur (A)

Answer:
If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use
