BIO 1114 Lab Final Study Material

What should your hypothesis represent?

A possible explanation for a problem or observation

Which of the following phases are part of the four-phase model of the scientific method?

Conclusion, Hypothesis, Analysis

What do you do in the hypothesis phase?

Formulate a statement of predicted behavior

What is the purpose of a control group in scientific experiments? Graph the results. Manipulate the hypothesis to fit the data. Make calculations based on the raw measurements.

Option 3 only

When pillbugs are placed in a choice chamber, which of the following behaviors indicates a preference for the test substance?

Pillbug spends more time in chamber with test substance

How is a control group treated in a scientific experiment?

The control group receives all the same treatments except the experimental variable.

During which phase of the scientific method are the results of a test evaluated for agreement with the original predictive statement

analysis

Which phase of the scientific method might produce charts or graphs?

conclusion

Pillbugs detect the presence of food with a sense similar to which human sense? Sight Smell Touch Hearing

smell

How does a pillbug react when it is attracted to a substance?

moves toward it

Which best describes the diet of pillbugs?

omnivore

During the analysis phase of the scientific method, measurements like mean, range, and variation may be calculated. charts and graphs are created to represent the data. the raw data is summarized. the data's significance is examined to determine how much variation is attributed to chance. there is discussion of the results.

options 1, 3, 4

In an experiment determining the effects of antibiotics on the treatment of pneumonia in mice, two groups of mice with pneumonia are compared. One group, group A, receives no antibiotic, and the other group, group B, receives 10 mg/kg of body weight of a new antibiotic. Besides the administration of the antibiotic, there are no differences between the two groups of mice. What is the purpose of group A?

To calculate an approximate concentration of antibiotic to use in treating pneumonia in humans To ensure that the experiment is statistically valid To ensure that only the treatment with antibiotics has an effect on the pneumonia To measure how much antibiotic is most effective in treating pneumonia in mice Option 3 is correct

which phase of the scientific method comes first?
