The fоllоwing describes а scientific investigаtiоn. Pleаse read the text and then answer the question that follows. A research scientist was studying lizards. The scientist wanted to know if lizards would run faster if they consumed more glucose. All the lizards would be the same species. The lizards would be fed crickets that would be injected with 0%, 5%, 10%, 15%, 20%, and 25% glucose. The lizards would be fed in their housing, not while racing because you don’t want them to get sick. The scientist made a lizard sized racetrack which included little infrared light beams connected to a computer. When the lizards ran down the track a computer would record their time when they went through the lights. The scientist found that lizards that ate crickets with 25% glucose ran the fastest (10 m/s). Lizards that ate crickets with 5% glucose ran the slowest (2 m/s). Lizards that ate crickets with 20% glucose ran (8 m/s), those that ate crickets with 15% glucose ran (6 m/s), and those that ate crickets with 10% glucose ran (4m/s). (m/s = meters per second) List two controlled variables from the experiment.
