1. The aspect of MacConkey agar allows for the determination of which bacteria are lactose fermenters and which are not.
2. An agar that uses a high salt concentration to limit the growth of one type of bacteria over another would be considered
3. A blood agar plate contains sheep red blood cells and allows for the determination of hemolytic capabilities for all bacteria that grow on the agar. This would make this type of agar.
4. EMB agar uses lactose and two dyes that allow it to be between the blue-black colonies of E. coli and the pinkish colonies of all other enteric bacteria.
