Nuclear fusion of hydrogen produces more energy than nuclear fission of uranium. a student claims that this means that fission–based power plants are safer, and we should not build fusion–based plants. which most accurately disputes the student's argument? (2 points)
the most dangerous aspect of nuclear power is radioactive waste, which fusion does not produce.
both nuclear fission and fusion produce large amounts of greenhouse gases.
nuclear fusion produces far more dangerous chemicals than nuclear fission does.
the more energy a power plant produces, the safer it is.

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.
