Textbook Question
Chapter 1, Problem 17RQ
You performed an experiment in which you measured the volumes of nine slices of potato, then soaked the slices in solutions of different salinities for 30 minutes. At the end of 30 minutes, you again measured the volumes of the nine slices. The changes you found were:
- a. What was the independent variable in this experiment? What was the dependent variable?
- b. Can you tell from the information given whether or not there was a control in this experiment? If there was a control, what was it?
- c. Graph the results of the experiment using the most appropriate type of graph.

A well-designed experiment will contain both positive and negative controls. Which of the following is a false statement?
Choose one from the following:
(A) a positive control experiment is missing some of the components of the experiment and should give a negative result
(B) a positive control experiment contains all of the components of an experiment and should give a positive result
(C) a negative control experiment is missing the element being tested and should give a negative result
(D) if there are multiple components of an experiment, there should be multiple negative controls
(E) if a negative control experiment give positives results, it is likely that the experiment is contaminated
What is the independent and dependent variables? Also what are the controlled variables and the controls in this experiment?
What is the independent variable?
What is the dependent variable?
Suggest a control for this experiment?

She believes that one needs to combine no snacking with the elimination of carbohydrates in their meals. Please explain how Dr. Vanier may test this hypothesis by describing the research design. Specify the independent variable(s), dependent variable(s), and the name of the design. Finally, describe what she needs to find (i.e., what type of effect and what it looks like) in the experiment to support her hypothesis.

You need to draw your own diagram and use short sentences to explain the steps and/or important points, deductions.

After the week of treatment all students are given the same test. What is the dependent variable? Select the best answer. The students. The amount (250 mg). Time. The test scores.

Question 1 options: A) the change in the dependent variable may be solely attributed to the change in the independent variable B) any and all effects on all experimental values are measured C) the change in the dependent variable may be solely attributed to the change in the extraneous variable D) the change in the independent variable may be solely attributed to the change in the complex variablearrow_forwardA biology student is investigating the claim that the temperature can be predicted by counting cricket chirps. He has collected data and comes up with the linear model T=39.2+0.233r, where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. Interpret the slope of the equation. The model predicts a decrease of 0.233 degrees for each increase of 1 chirp per minute. The model predicts a decrease of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 0.233 degrees for each increase of 1 chirp per minute.arrow_forwardWhich question will your experiment investigate?
