A group of scientists have been asked to conduct a study on how hazardous waste will affect the surrounding plant and animal
life. The scientists decided that the best way to complete the study is to conduct a controlled experiment in a laboratory. Which
of the following is the most likely reason the scientists will use a controlled experiment instead of placing hazardous waste in an
area to see if effects?
O
They expect the hazardous waste in the natural environment will have less of an effect than hazardous waste in their
controlled environment.
O They think using a controlled experiment will provide them with more results.
○ They can use different species than the plants and animals found in the real ecosystem.
O They can study the effects of hazardous waste without harming surrounding plant and animal life.

The most likely reason the scientists will use a controlled experiment instead of placing hazardous waste in an area to see its effects is: - They can study the effects of hazardous waste without harming surrounding plant and animal life. In a controlled experiment, scientists can create a setup where they expose a specific group of plants or animals to the hazardous waste while keeping another group unaffected. This allows them to observe and measure the direct impact of the waste without causing harm to the natural ecosystem. By controlling the variables and conditions in the experiment, scientists can isolate the effects of the hazardous waste and analyze them accurately. Furthermore, conducting a controlled experiment enables scientists to establish a baseline for comparison. They can observe how the plants or animals react when exposed to different concentrations of hazardous waste, helping them understand the potential consequences on a controlled scale before extrapolating to real-world scenarios. Overall, using a controlled experiment provides a controlled and ethical way for scientists to study the effects of hazardous waste without risking harm to the surrounding plant and animal life, ensuring accurate results and minimizing environmental impact.
