Campbell's Biology, 9e (Reece et al.) Chapter 4 Carbon and the Molecular Diversity of Life This chapter focuses on the chemistry of carbon and organic compounds. Students should be able to identify the nature of the bonds between carbon and other elements (nonpolar versus polar), the different types of weak bonds and interactions, the various types of isomers, the basic functional groups of organic molecules, and their relative solubility in water. The abiotic formation of organic molecules from inorganic molecules is important in the origin of life. Multiple-Choice Questions 1) The element present in all organic molecules is A) hydrogen. B) oxygen. C) carbon. D) nitrogen. E) phosphorus. Answer: C Topic: Concept 4.1 Skill: Knowledge/Comprehension

Campbell's Biology, 9e (Reece et al.) Chapter 2 The Chemical Context of Life This chapter presents basic chemical principles for understanding the chemical context of living organisms, from atomic structure to the nature of chemical bonds and an introduction to chemical equilibrium. These questions focus on elements most important to life or the study of life, including the elements that comprise organic molecules and important trace elements. Some isotopes are important in geologic dating and in biological tracer studies. How elements participate in forming different types of chemical bonds is essential to mastering subsequent topics on the behavior and properties of biological molecules, structures, and energy metabolism.

Introductory Questions #1 Name the seven main properties of life. (Pg. 3) Which of the hierarchial levels of biology is the lowest in regard to carrying on and sustaining all life activities and is the fundamental unit of life? (pg 5) Introductory Questions #1 3. In your own words briefly describe what ?emergent properties? are. 4. How is negative feedback different from positive feedback? (pg. 11) What do these mechanisms do for a living thing? 5. Name the three domains of life. Which domain includes four out of the six kingdoms of life? 6. Why is natural selection considered the ?mechanism? for evolutionary adaptations to occur? 7. How is a hypothesis different from a theory?

Assignment 2 ? Chemical Bonds In this world there are many different kinds of living organisms. All organisms are composed of atoms, that bond together to make the necessary components of a living organism. There are three identified chemical bonds that are recognized, they are ionic bonds, covalent bonds and hydrogen bonds. All bonds are not created equal, just ask the electrons!

Crystalline solid - solids with regular, repeating geometric arrangements of atoms, ions, or molecules Amorphous solids - noncrystalline solid with random arrangement of atoms or molecules ? **crystalline solids are more common and well-known ? Arrangements can be thought of as packing marbles together in a box (especially since atoms are spherical) We can reduce space between atoms--but not eliminate it--by rearranging the atoms in the structure "packing efficiency" - percentage of total volume that is actually occupied by atoms in a crystal lattice Affected by density of the material ? ? ? Types of Structures ? ? Cubic Crystal lattices: ? ? ?
