Which two sentences describe unethical behavior by a scientist? Donnie is a geology researcher at Baxter's Laboratory in Seattle, Washington. He keeps his lab tidy; he believes that cleanliness and order help avoid expensive accidents that may occur in the lab. Donnie is also very determined; he continues performing an experiment until he reaches the conclusion that he wants and expects. Sometimes, when Donnie is unhappy with how an experiment has turned out, he chooses not to share his findings with the public or his colleagues. But he always makes sure to put on goggles and follow the proper safety procedure before beginning an experiment.
