Acknowledgments

Each chapter of this book was thoroughly reviewed several times as it moved through the development process. Reviewers were chosen on the basis of their demonstrated talent and dedication in the classroom. Many of these reviewers were already trying various approaches to actively engage students in lectures, and to raise the scientific literacy and critical thinking skills among their students. Their passion for teaching and commitment to their students was evident throughout this process....

Anorexia and Bulimia

Eating disorders that make you underweight cause health problems as severe as those caused by overweight. Anorexia, or self-starvation, is rampant on college campuses. Estimates suggest that one in five college women, and one in 20 college men restrict their intake of Calories so severely that they are essentially starving themselves to death. Others allow themselves to eat, sometimes very large amounts of food (called binge eating), but prevent the nutrients from being turned into fat by...

Analyzing and Applying the

Review Figure 15.25 on the preceding page. How would you expect the carrying capacity of the population to change if the flies are supplied with a greater amount of food What other factors might influence carrying capacity in this environment 2. Imagine two human populations, each of which is made up of 5 million individuals. In one population, over 50 of the members are in the age group 0-20 years and about 2 are over 65. In the other, about 20 are 0-20 years old, and about 20 are over 65....

Recreational Drugs and the Nervous System

Drugs affect each of us differently because of differences in overall metabolism, weight, and gender. The gender difference is clearly illustrated by the way alcohol consumption affects males and females. It takes the liver one hour to metabolize one drink a 12-ounce beer, a 6-ounce glass of wine, or a mixed drink with one ounce of alcohol in a person who weighs approximately 150 pounds. Prior to its metabolism, the alcohol moves from the stomach throughout the body via the circulatory system....
