If you inoculate 1*10^6 CFU/ml E.coli, assuming a population doubling time of 20 minutes. Calculate the total number of cells present in a 100 ml flask of LB broth after 6 hours.
Initially, the number of cells was 1*10^6 CFU/ml * 100 ml = 1*10^8 CFUThe number of 20-minutes intervals in 6 hours is 18.The expected number of bacteria is 2^18*1*10^8 = 262144*10^8. It is approximately...

Do you think more genetic variation would help a species survive, or do you think less genetic variation would help a species survive? Why?
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.Genetic variation is advantageous because it enables some individuals and, therefore, a...

why d-block elements elements are called as outer transition elements and f-block elements as inner transition elements?
The d-block elements are called transition metals and have valence electrons in d orbitals. The inner transition elements are those who have their last 3 shells incompletely filled. The f...
