Kanye, Taylor's lab partner decided to perform a standard plate count from a sample of E. coli. Understanding that the plates should have 30 - 300 colonies, Kanye decide to aim for exactly 100 colonies.
If the original sample contained 1 x 10^8 CFU/ml, what is the total dilution that would yield 100 colonies?

Total dilution is 10^5 that would yield 100 colonies.

Explanation:

1 x 10^8 cfu/mL * 1/x = 100 colonies

x= 10^6 cfu/ml

So,

1*106cfu/ml *0.1 ml plated  

=10^5

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
