Answer #1

The bacteria culture grow differently because:

Facultative anerobes are organism that uses oxygen to make ATP but if oxygen is not present, they can switch to the condition where oxygen is absent..Culture A represent , develops turbidity that this group of organism uses oxygen , that give turbidity . On the other hand, the group of anaerobes are not using for  oxygen for cellular respiration or making ATP and formed a sediments.

    A haploid strain of yeast is treated with a mutagen called EMS. The different steps in the treatment and the analysis are the following: Step 1: Two tubes, labeled A and B contain 0.2 ml each of same yeast liquid culture. The concentration of yeast cells in the liquid culture was determined by a measure of the turbidity of the culture. This concentration is 4.4 x 109 cells/ml.

    General Electric. Enron. Not two companies that you would expect to be mentioned in the same breath. After all, General Electric is repeatedly in the top of Fortune magazine's "Most Admired” companies, and Enron will go down in history as one of the greatest failures and financial scandals in U.S. corporate history. So why would we mention both of these firms together? Because the fact is that throughout the 1990s and into the early 2000s, these companies actually approached their...

In the initial column assays with soil-and-sand mixtures, P. fluorescens PfO-1 and E. coli SLH25 had the highest and lowest adhesion values, respectively. Therefore, the sand column assay was optimized to yield the greatest difference in percent adhesion for these two strains. PfO-1 bacteria grown in minimal medium to the logarithmic phase were washed and suspended in either minimal...
