INTRODUCTION
The new MCAT Examination reflects an assessment of students knowledge of concepts and scientific skills, along with the ability to apply those skills and concepts to the analysis of problems and questions related to biological systems. The 375-minute exam evaluates this knowledge in four major areas: (1) Biological and Biochemical Foundations of Living Systems (95 minutes), (2) Chemical and Physical Foundations of Biological Systems (95 minutes), (3) Psychological, Social, and Biological Foundations of Behavior (95 minutes), and (4) Critical Analysis and Reasoning Skills (90 minutes). Ten Foundational Concepts outline the topics included within these major areas. This book addresses Foundational Concept 4 under Chemical and Physical Foundations of Biological Systems, including those areas of physics that underlie an understanding of questions related to these areas:
Foundational Concept 4: Complex living organisms transport materials, sense their environment, process signals, and respond to changes using processes understood in terms of physical principles.
The content categories for this foundational concept that are included in this book are:
4A. Translational motion, forces, work, energy, and equilibrium in living systems
4B. Importance of fluids for the circulation of blood, gas movement, and gas exchange
4C. Electrical circuits and their elements
4D. How light and sound interact with matter
4E. Atoms, nuclear decay, and electronic structure
In testing students scientific inquiry and reasoning skills, MCAT questions will ask them to combine their knowledge with these inquiry and reasoning skills: (1) Knowledge of Scientific Concepts and Principles, (2) Scientific Reasoning and Problem Solving, (3) Reasoning About the Design and Execution of Research, and (4) Data-Based and Statistical Reasoning. Questions in this book emphasize these skills from all areas of inquiry and reasoning: identifying scientific principles and the relationships between them, using various representations (verbal, symbolic, and graphical), identifying observations and applications related to physics concepts, using mathematical equations to solve problems, reasoning about physics concepts, evaluating explanations and predictions, drawing conclusions from observations and evidence, identifying independent and dependent variables, analyzing graphical information to draw conclusions, and using data to make predictions or explain relationships between variables.
