Question

the passage below describes an experiment. read the passage and then follow the instructions below. in her laboratory, addison studied the movements of tiny roundworms, which she kept in petri dishes containing worm food. she placed the same number of healthy worms on each of 18 dishes. addison kept six of the dishes at 15°c, six dishes at 20°c, and six dishes at 25°c for one hour. using a microscope, addison recorded 30 - second videos of the worms on each dish. later, she watched the videos and calculated the average speeds of the worms as they moved. identify the question that addisons experiment can best answer. does temperature affect the number of minutes per day that worms spend moving? is a worms speed affected by the temperature of its surroundings? does the number of worms on each dish affect how fast the worms move?

Explanation:

Addison varied the temperature of the worm - containing dishes and measured the average speeds of the worms. So, the experiment is focused on the relationship between temperature and worm speed.

Answer:

Is a worm's speed affected by the temperature of its surroundings?
