Ann Quinlan was 21 y/o When she mixed Valium and alcohol by mistake. She was in a coma for about 6 years with no hope of ever getting well. Her parents fought for her to be allowed to be taken off of the machines and allowed to die. The courts ruled in her favor and she was slowly removed from the machines. But after having the machines removed she did not die and lived for about 10 more years. Her case started the “right to die” motion.
Answer:
C. The scientist's conclusion is flawed because the number of hours of sunlight changed and, therefore, the experiment is not controlled.
Explanation:
A controlled experiment is an experiment used to test a single variable at a time. The variable that is being tested is called the independent variable, and it is directly manipulated by a scientist. The rest of the variables need to remain unchanged in order not to get wrong results like the scientist in the given scenario.
As the scientist is trying to see how gamma rays affect marigolds, only the gamma ray exposure is supposed to change throughout the experiment. The amount of water remained the same, but the number of hours of sunlight didn't. That's why we don't know what exactly affected the growth of marigolds - the sunlight or the gamma rays? And that's why the scientist's conclusion is flawed.
