How are bacteria able to change their patterns of protein synthesis so quickly in response to environmental changes?

#Unit 3. Fundamental Processes
  1. mRNAs that are produced are short-lived and degraded within a few minutes of being synthesized.

  2. mRNA have long lifespans, allowing the bacteria to use them many times for translation.

  3. mRNA is stored for later use.

  4. Operons are activated in the presence of transcription factors.

A  plant species arrives at  an  island  for the first time, where it  is  exposed to  a  new set of  pollinators.  Over the course of 20 generations, the characteristics of its flowers change. The figures above show the frequency distribution of petal length in the original colonizing population (Figure 1) and 20 generations later (Figure 2). Which of these explanations is consistent with the observed change in petal length?
