Written by an experienced teacher and examiner, Cambridge IGCSE Biology Workbook helps students build the skills required in both their theory and practical examinations. The exercises in this write-in workbook help to consolidate understanding and get used to using knowledge in new situations, develop information handling and problem solving skills, and develop experimental skills including planning investigations and interpreting results. This accessible book encourages students to engage with the material. The answers to the exercises can be found on the Teacher's Resource CD-ROM.

    

    A man who sees cartoon characters running across the room; a girl whose world turns all Alice in Wonderland; another who transforms into a ragdoll whenever she even thinks about moving.The brain is the most complex structure in the universe. Neurologists must puzzle out life-changing diagnoses from the tiniest of clues. It’s the ultimate medical detective work. In this riveting book, one of the UK’s leading neurologists will take you with her as she follows the clues of her patients’ symptoms. It’s a journey that will open your eyes to the unfathomable intricacies of our brains, and the infinite variety of human capacity and experience.

    Do you want your students to just take psychology or to experience psychology? Laura King's approach to introductory psychology embodies a balanced consideration of functioning behavior as well as dysfunction and a view of psychology as an integrated whole.

    Using meticulous multidisciplinary science, as well as reviewing the history of our understanding about evolution, this book makes the case that aging is not something that “just happens,” nor is it the result of wear and tear or a genetic inevitability. Rather, aging has a fascinating evolutionary purpose: to stabilize populations and ecosystems, which are ever-threatened by cyclic swings that can lead to extinction.When a population grows too fast it can put itself at risk of a wholesale wipeout. Aging has evolved to help us adjust our growth in a sustainable fashion as well as prevent an ecological crisis from starvation, predation, pollution, or infection.This dynamic new understanding of aging is provocative, entertaining, and pioneering, and will challenge the way we understand aging, death, and just what makes us human.

    Author Dr. Bruce Lipton is a former medical school professor and research scientist. His experiments, and that of other leading-edge scientists, have examined in great detail the processes by which cells receive information. The implications of this research radically change our understanding of life. It shows that genes and DNA do not control our biology; that instead DNA is controlled by signals from outside the cell, including the energetic messages emanating from our positive and negative thoughts. Dr. Lipton's profoundly hopeful synthesis of the latest and best research in cell biology and quantum physics is being hailed as a major breakthrough showing that our bodies can be changed as we retrain our thinking.

    The text's major theme "Changes, Choices, and Constraints" explores: Contemporary "changes "in families and their structure Impacts on the "choices "that are available to family members ""Constraints ""that often limit our choices Through this approach, students are better able to understand what the research and statistics mean "for themselves"! Marriages and Families balances theoretical and empirical discussions with practical examples and applications. It highlights important contemporary changes in society and the family. This text is written from a sociological perspective and incorporates material from other disciplines: history, economics, social work, psychology, law, biology, medicine, family studies, women's studies, and anthropology. "More about the themes: " "Changes"Examines how recent profound structural and attitudinal changes affect family forms, interpersonal relationships, and raising children. It reaches beyond the traditional discussions to explore racial-ethnic families, single-parent families and gay families as well as the recent scholarship by and about men, fathers, and grandfathers. Contemporary American marriages and families vary greatly in structure, dynamics, and cultural heritage. Thus, discussions of gender roles, social class, race, ethnicity, age, and sexual orientation are integrated throughout this book. To further strengthen students understanding of the growing diversity among today's families, the author included a series of boxes that focus on families from many cultures. "Choices"On the individual level, family members have many more choices today than ever before. People feel freer to postpone marriage, to cohabit, or to raise children as single parents. As a result, household forms vary greatly, ranging from commuter marriages to those in which several generations live together under the same roof. "Constraints"Although family members choices are more varied today, we also face greater macro- level constraints. Our options are increasingly limited, for example, by government policies. Economic changes often shape family life and not vice versa. Political and legal institutions also have a major impact on most families in tax laws, welfare reform, and even in defining what a family is. Because laws, public policies, and religious groups affect our everyday lives, the author has framed many discussions of individual choices within the larger picture of the institutional constraints that limit our choices.To learn more about the new edition, click here to visit the showcase site.
