Explanation:

In general, the presence of more bacteria in a water sample can lead to discoloration (like a yellowish or greenish tint) due to bacterial growth, metabolic by - products, or the presence of organic matter associated with bacteria. The right - hand water sample has a yellow color, while the left - hand one is clear. So, based on the observation of color (a common indicator of bacterial presence in such simple visual tests), the water sample in the right test tube (the yellow - colored one) is likely to have more bacteria.

Answer:

The water sample in the right test tube (the yellow - colored one) has more bacteria.
