A culture medium consisting solely of dextrose and inorganic salts would be considered a ____________ medium.
a. complete
b. differential
c. complex
d. minimal
e. selective
In this case, a minimal medium consist typically of a carbon source which serves as energy source (in this example, the dextrose) and inorganic salts which serves as elements source in order to produce protein and nucleic acids. So, the correct answer is minimal

1. The type of genetic exchange between bacterial cells that can happen between isolated DNA and a live bacterial cell is: a. conjugation b. transduction c. transversion d. transformation 2. An Hfr strain of E. coli with genotype a+b+c+d+e+f+ is mated with an F¯ auxotrophic strain with the genotype a¯b¯c¯d¯e¯f¯. Conjugation is stopped at 10 minute intervals and the genotypes of the resulting conjugants are determined. The following results are obtained: after 10 minutes e+ after 20 minutes a+ e+...
