Exam Board: OCR Level: A level Subject: Science / Biology First teaching: September 2015 First exams: June 2017 An ActiveBook is included with every Student Book, giving your students easy online access to the content in the Student Book. They can make it their own with notes, highlights and links to their wider reading. Perfect for supporting work and revision activities. Student Book 1 supports a standalone AS course and provides the first year of a two-year A level course; Student Books 1 and 2 together support the full A level course. A cumulative approach to learning constantly builds on what has previously been taught. The chapter openers highlight prior learning requirements and link to future learning. The required maths skills are highlighted at the start of each chapter providing opportunities for students to check understanding and remedy gaps. Bigger spreads require students to read real-life material that's relevant to the course and use knowledge in new contexts. Accompanying questions require students to analyse how scientists write, think critically and consider issues. Preparing for your exams sections highlight the key differences between preparing for an AS and full A level exam. Practice question spreads provide opportunities for students to regularly check their understanding using questions written in the style of the new exams from day one.

The Arctic Charr is a fish of wild places. It is the fish that is capable of thriving in the harsh conditions found in the fresh waters of the far north where no other fish can. Its toughness in these extreme environments, its stunning beautiful colours (more usually associated with tropical fish) and the speed with which it is known to adapt to new environments, ensure that "charismatic" is used in any description of this species. Although widespread and often abundant, surprisingly little is known about Arctic Charr in 21st century Scotland. In this volume, two ecologists with a life-long passion for this species, distil what is known, and just as importantly what is not, about Scottich Arctic Charr.

Biostatistics for the Biological and Health Sciences brings statistical theories and methods to life with real applications, emphasis on real data, and a friendly writing style. It suits a variety of students in their first statistics course and uses minimal algebra. Abundant examples and emphasis on real data help you develop skills in critical thinking, technology and communication. This collaboration from 2 biological sciences experts and the author of the #1 statistics book is an excellent introduction that is also highly readable, understandable and relevant. The 3rd Edition incorporates the latest methods used by professional statisticians. It offers a wealth of new data sets, examples, and exercises (such as those involving clinical trials, COVID-19, biometrics, and anthropometrics) and includes features that address all recommendations included in the Guidelines for Assessment and Instruction in Statistics Education (GAISE) as recommended by the American Statistical Association.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Life does not exist without the intestine. The source of the heart and mind exists in what makes the intestine move, searching for food or reproduction. Higher living animals have been borne from the intestine and sustained by it. This suggests that the heart and mind is located in the internal organs. The character of a patient who underwent the simultaneous transplant of the heart and lungs, has been replaced by that of the donor. The author thinks that the heart and mind dwells in the intestine such as the heart, the reproductive organ and the face. He, a world-famous doctor for the development of artificial organs, has searched for the origin of the heart and mind by elucidation of the evolution of the vertebrate in his own way.
