The Process of Science Through Mutations/Cancer For each question, choose/fill in the best answer. In some cases there are "good" incorrect answers that may be partially credited. If you need clarification, please do not hesitate to ask. All answers must be readily discernible any questionable marks will be assumed incorrect. All questions worth one point unless otherwise noted. in order, what are the steps used in the process of a scientific study? A.) Generate hypotheses based on published literature, test hypotheses, and make conclusions supported by data. B.) Generate hypotheses, conduct experiments, research literature, make conclusions supported by the literature, and analyze data. C.) Make initial observations that generate questions, generate hypotheses, study the literature, and make conclusions supported by data. D.) Make initial observations that generate questions, study the literature, generate hypotheses, test the hypothesis with experiments and analyze the data, make conclusions that are supported by data, communicate results. E.) None of the above. In your own words, what is a scientific hypothesis? I observe that squirrels living In the southeastern United States are much thinner than squirrels living in the northeastern part of the country. I theorize that this is because the squirrels that live in the northeast have greater fat reserves for the winter months when food Is scarce. Is this a scientific theory? A.) No, because it cannot be proven B.) No, It is just a hypothesis: it has not been supported scientifically through experimentation C.) Yes, I am taking into consideration physiological reasons for their larger size, so it is scientific D.) Yes, it is a good, educated guess E.) None of the above In a well-designed experiment the sample size: A.) depends on the particular experiment B.) should be around one hundred C.) should be as large as possible with regard to background, demographic, or any other factors D.) should not be very large, so the data can be more easily interpreted E.) None of the above In medical studies, test subjects are often given a____, a harmless, inactive medication in order to reduce bias in the study. A.) Controlled variable B.) Double-blind test C.) Placebo D.) Supplement E.) None of the above

Explanation / Answer

To answer a question objectively, the basic structure of scientific study should have these 5 steps in a logical sequence.

2. Scientific Hypothesis

Making an assumption based on the observations and knowledge that one has about a phenomenon, but for which there is no scientific explanation available. Hypothesis has to be tested through experiments. The outcome of the experiments is pre-determined. However, results need not necessarily be always in tune with the hypothesis formed.

3. B

A scientific theory is an explanation that is confirmed by repeated experiments and observations. Scientific theories are not mere guesses.

4. A

Sample size depends on different factors of the experiment. The total size of the study population is one of the major deciding factors. Sample size will also vary depending on nature of the study i.e. whether it is a single group experimental study, study of continuous variables (such as concentration of a substance in a chemical) or time based experiments etc.

5. C

Placebo is used in a medical study to find out whether the effects of a drug treatment is effective than no treatment at all.
