Incomplete question. The full question reads;
Two students are planning an experiment that will test how planaria (aquatic flatworms) respond to different environments. They will conduct two investigations—one that tests the worms’ responses to different water temperatures and one that tests the worms’ responses to different levels of acidity. Student 1 wants to buy two groups of flatworms and use a different group for each investigation. Student 2 thinks the same group of worms should be used for both investigations.
Do you think either student’s method would give more accurate results? Why or why not? Explain your response.
Answer:
No.
Step-by-step explanation:
This is the case because it could be observed that only Student 2 thinks the same group of worms should be used for both investigations. This ultimately would result in more accurate results as both specimens can be compared to see if there's a difference in the way they respond to different environments.
However, by using a different group for each investigation, Student 1 may more likely get less accurate results.
