The school physician performed an experiment to investigate the effects of aerobic exercise on high school freshmen. He examined 25 student volunteers and found them to be in good health. He then had the students perform aerobic exercises, such as jogging, swimming, and bicycling. The doctor recorded the students’ pulse rates before each activity, during each activity, and after each activity. Which was the dependent variable in this experiment?  A. the pulse rates B. the exercises C. the volunteers D. The physician

A real cell is too far away to study. • D. A real cell is too dangerous to study.

What is the dependent variable in this experiment?   • A. the amount of vitamin C •  B. the type of illness a person gets  • C. the brand of vitamin C being used • D. the number of illnesses a person gets

A graphic designer shows her plans for a new shopping mall by using a scale model of the actual mall. Why did the graphic designer most likely use a scale model and not another type of model? • A. She used a scale model because she wanted to show quantitative situations of shops.  • B. She used a scale model because she wanted to show something that is too large to see. •  C. She used a scale model because she wanted to show the patterns of behavior of shoppers.  • D. She used a scale model because she wanted to show a process that cannot be copied in real life.

. How is a mathematical model most limited in its use?  • A. It is limited by the existing data and variables.  • B. It is limited by ideas that can cause misconceptions. •  C. It is limited by the size of the object that is being modeled. •  D. It is limited by the model not behaving like the object it represents.
