The doctor set up a diagnostic test for George in which he received a low dosage of radioactive iodine compounds. The results of the levels of radioactive iodine in his blood were then compared to the levels of radioactive iodine in the blood of a healthy human. The results are shown in the graph below. 100 George 80 60 40 healthy human 20 3 Time After Admnistration of Radioactive lodine (days) 3. a. Write the hypothesis the doctor was investigating with this test. Answer: b. What was the purpose of giving a healthy human radioactive iodine compounds in this experiment? Answer: C. Do the results shown in the graph support the hypothesis? Explain your answer. Answer: Suggest why the graph for the healthy human rose after approximately two days. Answer: е.
