Impact Figures motivate and inspire students by demonstrating the dramatic impact of recent discoveries in biology.
These figures have been carefully developed to provide a balance between realism and teaching effectiveness.
Examples include new material on global growth of photosynthetic protists (Chapter 28 endangered molluscs (Chapter 33 and the impact of a pathogenic chytrid fungus on amphibian population declines (Chapters 31 and 34).
Introducing the global nature of climate and its effects haegemonia the solon heritage 2.01 trainer on life at the beginning of the chapter provides a logical foundation for the rest of the material.The burgeoning importance of nucleic acids throughout biology has prompted us to expand our coverage of DNA and RNA structures in this first unit.These Evolution sections, highlighted by a new Evolution banner, demonstrate to students that evolution is central to every area of biology.In developing the Ninth Edition, we have continued to balance the old and the new to provide students with a basic understanding of plant anatomy and function while highlighting dynamic areas of plant research and the many important connections between plants and other organisms.Unit Eight Ecology Our revision was informed by the fact that biologists are increasingly asked to apply their knowledge to help solve global problems, such as climate change, that already are profoundly affecting life on Earth.Selected figures have been rendered in a 3-D art style to enhance understanding.One major revision goal was to provide more explicit discussion of the evolutionary aspects of plant biology, such as the coevolution of insects and animal pollinators (Chapter 38).Also, we encourage students to connect what they learn about DNA replication and chromosome structure in Chapter 16 to the material on chromosome behavior during the cell cycle in Chapter.Other revisions aim to keep students focused on fundamental concepts amid the details of complex systems.Make Connections, questions are integrated into each chapter in selected Concept Checks, figure legends, Impact Figures, and in the end-of-chapter assessment section. .Throughout the unit, new state-of-the-art images and material on current and compelling topicssuch as circadian rhythms fm database editor 2013 (Chapter 40 novel strains of influenza (Chapter 43 the effects of climate change on animal reproductive cycles (Chapter 46 and advances in understanding brain plasticity and function (Chapter 49)will.Data Analysis Tutorials connect students with real data from online databases and guide them in analyzing and interpreting data in a controlled environment.Changes include the reorganization of the Item Library to match the Key Concepts structure in the text.In Chapter 9, we simplified the glycolysis figure and emphasized pyruvate oxidation as a separate step to help students focus on the main ideas.This section also directs students to the eText and Study Area for additional resources.Make Connections Tutorials in MasteringBiology connect content from two different chapters using art from the book.Expanded MasteringBiology online resources include: Improved User Interface: MasteringBiology has been streamlined to make the system more user-friendly and efficient.So, for example, Chapter 27 now presents new findings on the evolutionary origin of bacterial flagella.Each, make Connections, question challenges students to move beyond memorization and gain a deeper understanding of biological principles by asking them to relate the content of a chapter to what they learned earlier in the course.For example, Chapter 22 now presents research data on adaptive evolution in soapberry bugs, fossil findings that shed light on the origins of cetaceans, and an Impact Figure on the rise of methicillin-resistant Staphylococcus aureus.
Chapter 55 now explores restoration ecology together with ecosystem ecology because successful restoration efforts depend on understanding ecosystem structure and function.
