  9. Each of the following steps is involved in scientific thought except questioning ideas. making observations. evaluating evidence. preserving bias.

  10. In which aspects of science are ethics involved? running experiments with humans and other animal reporting results of controlled experiments publishing scientific studies All of the above

  11. All objects in the universe are subject to scientific skepticism the law of gravity the law of indirect observation. the International System of Units.

  12. In which three areas can studying science aid a nonscientist? health, consumer issues, and solving community problem health, consumer issues, and following universal laws consumer issues, following universal laws, and reinstating conventional wisdom health, critical thinking, and reinstating conventional wisdom

  13. What is a control group? a group of people in a scientific study a group of scientists in charge of conducting an experiment a group that serves as a standard of comparison in an experiment a group that receives only an experimental treatment

  14. In a controlled experiment, what do scientists measure? how many dependent variables they have how many independent variables they have how the dependent variables change in response to changes in the independent variable how the independent variables change in response to changes in the dependent variable

  15. What is the main reason for running a controlled experiment? to make observations to test a hypothesis to formulate new questions to get information for a study

  16. Which of these could be useful in a microbiology lab? electron microscopy sterile technique Both (a) and (b) Neither (a) nor (b)

  17. Which of the following is true about theories and hypotheses? A hypothesis is highly tested, but a theory is not testable. A hypothesis is a general explanation, but a theory is a specific prediction. One hypothesis can lead to many theories Several related hypotheses can be incorporated into a theory

  22. A scientist is investigating a new treatment for a disease that affects thousands of people. Many people with this disease volunteer to be part of the study. Which of the following is an ethical concern that the scientist must address before conducting the study? The scientist must ensure that the treatment will be effective. The scientist must ensure that the study’s results will not be shared with other scientists The scientist must inform the volunteers about the potential dangers of participating in the study. The scientist must demonstrate the treatment on him or herself.

  23. Which of the following is an example of scientific skepticism?
