Homework Answers
1) The most common and a good medium to support the best growth of bacteria is LB(Lysogeny broth) medium or nutrient broths.
2) The agar makes a media viscous and is used for cultivation of microbes supporting growth of a wide range of organism.The liquid medium does not posses agar as agar is a solidifying gel.The semi solid medium contains agar concentration 0.5% or less while the solid medium contains 1% and more concentration of Agar .
So , as in question above , 1% to 5% agar makes the medium solid.

The researchers grow and maintain the Ames test bacteria in liquid media containing histidine. They then prepare plates (semi-solid media) with media that lacks histidine. They also prepare tubes of media that is between the semi-solid and liquid media (soft agar) that contains trace amounts of histidine. They inoculate tubes of the soft agar with the mutant Ames test bacteria and add one of the following - 100 l of (1) chemical A in a solvent, (2) chemical B in...
