Question

dependent amount of weight loss (5) Suggest a control treatment for each of the following experiments: a. (1 pt.) Plants are exposed to different intensities of light and the amount of oxygen produced during photosynthesis is recorded. depend ut Ditterent intensities of light. b. (1 pt.) Frogs are captured from polluted ponds. The investigator records the number of limb deformities froy Cciplilled from Ponds. Clean c. (1 pt.) Patients taking different doses of a new medication were monitored for weight loss. talking different doses of rew medication

Answer 1

Q 5.a. A control plant is kept under the full sunlight condition.

Reason: Since this experiment has variable light intensity, the best control will be the natural sunlight condition to compare the production of oxygen under different light intensity.

Q 5.b. Frogs captured from clean pond

Reason: The probable cause for deformities hypothesized in this experiment is pollution in the pond. So, the best comparison will be with the frog which has been captured from the clean pond.

Q 5.c.Patient taking prescribed dose of the old medication available.

Reason: The experiment wants to check the role of the new medicine and the effect of dose on weight loss as compared to the other medication available. So the best control will be the patient who is under the old medication process.
