Why is proper waste disposal necessary during a scientific investigation?

Answer and explanation

Correct answer: To protect health and the environment

The direct answer is option D: proper waste disposal protects health and the environment. Scientific investigations may produce broken glass, sharp objects, chemicals, biological material, or ordinary waste. If such material is left carelessly, it can injure people, cause poisoning or infection, pollute soil and water, or harm plants and animals. The reasoning is: identify the waste; follow the laboratory or school instructions; separate hazardous and ordinary waste; place each type in its correct container; clean the work area safely. Option A is wrong because disposal rules are not meant to make an experiment last longer. Option B is wrong because disposal does not aim to reduce the number of instruments. Option C is wrong because waste disposal must never hide data or results. Option D is correct because safety and environmental protection are its main purposes. Memory cue: safe science protects people, places, and living things.
