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.
Caesar's bad traits were really a matter of perception. He achieved much success as a military leader who consolidated power and defeated enemies which led to amassing large amounts of foreign territory. He was very unpopular with the aristocrats of his time due to a number of his policies. He favor the poor and that angered the wealthy in his land. He also was suspected of aiming to become King of Rome due to his massive amount of power, this was not supported by the political system or the people of his time. He also had no fear of violence, even on massive scales. He committed many massacres on people, some in other lands, some who he promised retribution to due to being held captive as a child.
It's expression of subjective feelings, contractions, and first-person point of view.(:
