Notes to InstructorsChapter 2 The Chemical Context of LifeChapter 3 Water and the Fitness of the EnvironmentWhat is the focus of these activities?Living organisms function in the real world, so they are subject to all the laws of chemistryand physics. In addition, biological organisms and systems are variable. No two organisms areexactly alike, and no two systems are identical in form or function. As a result, our analysisof such systems tends to deal with statistical averages or probabilities. This means that it isdifficult to understand biological systems without having a good basic understanding ofchemistry, physics, and math (including probability and statistics).The vast majority of introductory biology students have studied inorganic chemistry in theirhigh school and first-year college chemistry courses. Many students compartmentalize theirknowledge, however. In some cases, the compartmentalization is so extreme that the studentsfeel uncomfortable dealing with chemical formulas and ideas outside of chemistry classes.Therefore, it is generally useful to review some of the basic ideas in chemistry and, at thesame time, demonstrate how they can be applied to understanding biological systems.What are the particular activities designed to do?Activity 2.1 A Quick Review of Elements and CompoundsThe questions in this activity are designed to help students review and understand:•atomic/molecular number, mass number, and atomic/molecular weight and howthey can be used to determine the reactivity of elements;•various types of chemical bonds and how they affect the structure and energeticsof molecules; and•the difference between a mole and a molar equivalent and how a knowledge ofthese can be used in biological applications.Activity 3.1 A Quick Review of the Properties of WaterThe questions in this activity are designed to help students review and understand theproperties of water and how they support life. Students are asked to review these keyproperties:•H2O molecules are cohesive; they form hydrogen bonds with each other.•H2O molecules are adhesive; they form hydrogen bonds with polar surfaces.•Water is a liquid at normal physiological (or body) temperatures.•Water has a high specific heat.•Water has a high heat of vaporization.•Water’s greatest density occurs at 4°C.Notes to Instructors1
