Beschreibung / Inhaltsverzeichnis:
Surveys of Biological Progress, Volume I is an 11-chapter text that covers the advances in some aspects of biology, including growth and development, gene, virus, hormones, and ecological studies. This book starts with an introduction to the status of biological education in school curriculum and to the nature of gene actions. The subsequent chapter deals with the salient features of tracer methods and their application in biological and biochemical studies. Considerable chapters are devoted to various topics of biological interest, including nutrition, reproduction, growth and development, virus-causing tumors, and the link between hormones and sex differentiation. These topics are followed by a discussion on the specific activities of growth hormones and their link with the phenomena of tissue growth and differentiation. The concluding chapters consider the improvement in plant breeding methods and the effect of environmental factors on vitamin C content of food plants. These chapters also review the contribution of ecological studies in delineating population issues. This book is of value to biologists, and biology teachers and students.
