Explanation:

• "mixed culture" refers to a culture with multiple types of organisms, not a discrete mound of cells.
• "Petri dish" is the container, not the mound of cells.
• "colony" is defined as a discrete mound of cells (usually from a single cell or a group of the same cells) growing on a solid nutrient surface.
• "selective medium" is a type of growth medium that selects for certain organisms, not the mound of cells.
