Big Era Three Farming and the Emergence of Complex Societies 10,000 ? 1,000 BCE. Join us for the world tour! STOP! I know what you?re thinking! Farming and complex societies? Where did they come from? I thought we were still hunting and gathering! Today 10k years ago 200k yrs ago Big Era 2 ?and changes have always been?and still are?part of human history. Let?s look for a minute at the changes that took place in Big Era Two. You DO remember Big Era Two, don?t you? Big Eras 3-9 Big Era 1 Farming and complex societies are the result of CHANGE? Today 10k years ago 200k yrs ago Big Era 2 Big Era Two is the era that covers the period from 200,000 to 10,000 years ago. Big Era Two was fraught with change. Shall we do a quick review?

Katie Bishop Dr. Heitschmidt English 10 January 21, 2013 The Tale of the Maid With them came a surly ferocious maid She cleaned a brothel, so ugly was she On her broad shoulders her kinky hair laid Her hair so naughty birds thought it a tree Her limbs and her body were long and gaunt The skin she had was as pale as a ghost Her feet; like clubs moved and clamored about Voice deep as a well, lake men she did boast Face bore a wart that resembled a horn Horse teeth she had such a big scary fright Dresses so tattered and looking forlorn She came on this journey; what a sad plight With a harsh and quick tongue she did retort Born a slave was she; a harsh history At the brothel she sat with no escort So secret was she with a life of mystery

Campbell's Biology, 9e (Reece et al.) Chapter 12 The Cell Cycle In this chapter, 24 questions are new, and 12 have been altered to incorporate new material from the textbook. As in the other chapters, any questions that depend on figures or introductory scenarios have been placed at the end of the chapter rather than in concept sequence. Multiple-Choice Questions 1) The centromere is a region in which A) chromatids remain attached to one another until anaphase. B) metaphase chromosomes become aligned at the metaphase plate. C) chromosomes are grouped during telophase. D) the nucleus is located prior to mitosis. E) new spindle microtubules form at either end. Answer: A Topic: Concept 12.1 Skill: Knowledge/Comprehension

Campbell's Biology, 9e (Reece et al.) Chapter 11 Cell Communication Students will encounter the topic of cell signaling repeatedly in this course and throughout their studies of biology. Therefore, the more confident they are regarding the basic principles, the more successful they are liable to be when encountering the topic. This chapter includes more higher-skill-level questions and makes connections to the principle of evolution as well as to other chapters of the text. Multiple-Choice Questions 1) Using the yeast signal transduction pathways, both types of mating cells release the mating factors. These factors bind to specific receptors on the correct cells, A) which induce changes in the cells that lead to cell fusion.

Campbell's Biology, 9e (Reece et al.) Chapter 7 Membrane Structure and Function Membranes and membrane transport are fundamental to cellular life. The concepts in this chapter require integration of concepts from previous chapters: the nature of water and hydrophobic versus hydrophilic molecules, the properties of lipid molecules and their role in regulating membrane fluidity, and the roles of proteins and carbohydrates in membrane function. The concepts of ion transport and electrochemical gradients across membranes are important foundations for the following chapters on energy metabolism. Finally, the bulk transport phenomena have important clinical significance in the immune system, during invasion by pathogens, and in cell signaling. Multiple-Choice Questions

Campbell's Biology, 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5, the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers, and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure, because this is central to understanding subsequent chapters on metabolism, molecular biology, and molecular medicine. Multiple-Choice Questions 1) Humans and mice differ because A) their cells have different small organic molecules. B) their cells make different types of large biological molecules.

Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1
