When a bacterium is introduced to a new environment with plenty of nutritional resources,binary fission will allow for rapid growth of the population (2-4-8-16-32-64 ...etc.).However,there is usually a slight lag before the rapid growth begins.What is the best explanation for this lag period?

A)It takes time for bacterial cells to duplicate enough organelles to digest new media.
B)It takes time to induce and amplify the production of the enzymes needed for binary fission.
C)Binary fission becomes more and more efficient after each cell division.
D)The new media contains compounds that turn on repressor proteins.
E)Structural genes act more slowly than metabolic genes.
