Question

Five separate SIM tubes were inoculated with organisms A through E. Which tubes produce hydrogen sulfide gas?

In this image, there are five labeled test tubes (A, B, C, D, and E) held in a blue test tube rack. Each test tube contains a liquid with varying colors and characteristics, indicating different experimental or observational results. - **Test Tube A**: Contains a liquid with distinct layers of dark brown and pink. This may indicate a reaction or separation of substances within the tube. - **Test Tube B**: Features a gradient from dark at the bottom to clear at the top. This suggests a settling process or density gradient. - **Test Tube C**: Appears to contain a uniformly light yellow liquid, indicating no visible reactions or layers present. - **Test Tube D**: Also holds a light yellow liquid similar to Tube C, suggesting comparable contents or conditions. - **Test Tube E**: Displays a dark layer at the bottom with a transition to a lighter color at the top, similar to Tube B but with more defined separation. These variations in color and layering within the test tubes could be part of an experiment demonstrating chemical reactions, solubility tests, or microbial growth under different conditions. Each distinct appearance may correspond to specific scientific observations or conclusions.
