What is biologia general?
Biologia general is the branch of science that deals with the study of living organisms, from their origin to their diversity, structure, function, reproduction, evolution and interaction with their environment. It encompasses various disciplines such as botany, zoology, microbiology, ecology, genetics, molecular biology and more. Biologia general aims to understand the nature of life, its origin, its diversity, its mechanisms and its patterns.
Why is biologia general important?
Biologia general is important because it helps us to understand ourselves and our place in the natural world. It also helps us to appreciate the beauty and complexity of life, as well as its challenges and problems. By studying biologia general, we can learn about the origin and evolution of life on Earth, the diversity and classification of living beings, the structure and function of cells and organisms, the processes of inheritance and variation, the mechanisms of adaptation and natural selection, the relationships between organisms and their environment, the impact of human activities on biodiversity and ecosystems, and the solutions for a sustainable development.
Who are the authors of biologia general?
The authors of biologia general are Marta Cervantes Ramírez and Margarita Hernández Hernández. They are both distinguished Mexican biologists and professors at the National Autonomous University of Mexico (UNAM). They have extensive experience in teaching biologia general at various levels of education. They have also participated in several research projects and publications related to biologia general. They have written this book with the aim of providing a comprehensive and updated source of information on biologia general for students and teachers.
Main Content
Structure and organization of biologia general
Units and chapters
The book is divided into five units that correspond to the main themes of biologia general. Each unit contains several chapters that develop specific topics within each theme. The units are:
Unit 1: The nature of science. This unit introduces the concept and characteristics of science as a way of knowing the natural world. It also explains the scientific method, its steps and applications.
Unit 2: The unity of living beings. This unit deals with the common features that define life and distinguish living beings from non-living things. It also describes the structure and function of cells as the basic units of life.
Unit 3: The continuity of life. This unit focuses on the processes that ensure the transmission and expression of genetic information from one generation to another. It also covers the topics of mitosis, meiosis, gametogenesis, fertilization, embryonic development, DNA structure and function, gene expression and regulation.
Unit 4: Evolution and biological diversity. This unit explains the origin and history of life on Earth, as well as the mechanisms that generate variation and change in living beings over time. It also covers the topics of natural selection, adaptation, speciation, classification, phylogeny, and the diversity of domains, kingdoms, and phyla of living organisms.
