What are the main topics of Libro Biologia 1 Estrada Polimodal.pdf?

Libro Biologia 1 Estrada Polimodal.pdf covers a wide range of topics related to biology, from the molecular to the ecological level. The book is organized into two blocks, each containing several chapters. Here is a brief overview of the main topics of each block:

Block 1: The cell: structural and functional unit of life

Chapter 1: The living beings: diversity and unity. This chapter introduces the characteristics of living beings, the classification of life forms, the origin of life and the evolution of living beings.
Chapter 2: The chemical composition of living beings. This chapter explains the levels of organization of matter, the biomolecules that make up living beings, such as proteins, carbohydrates, lipids and nucleic acids, and the role of vitamins and minerals.
Chapter 3: The cells. This chapter describes the cell theory, the shape and size of cells, the types of cells (prokaryotic and eukaryotic), the structure and function of cell organelles, and the transport of substances across the cell membrane.
Chapter 4: Cell metabolism. This chapter explores the concept of metabolism, the role of ATP and enzymes, the catabolic and anabolic processes, such as glycolysis, cellular respiration and photosynthesis, and the communication between cells.
Chapter 5: Cell division. This chapter examines the types of cell division (mitosis and meiosis), the cell cycle, the concept of ploidy, the origin of genetic variability and the process of cancer.

Block 2: The human organism as a complex and open system

Chapter 6: How does the human organism work? This chapter introduces the functions of the human organism (nutrition, relation and coordination, and reproduction), the concept of homeostasis, the levels of organization in the human body (tissues, organs and systems), and some examples of tissues (epithelial, connective, muscular and nervous).
Chapter 7: Health. This chapter defines health and its relation to quality of life, the factors that influence health, such as genetics, environment and lifestyle, how to prevent diseases, such as infectious diseases, non-infectious diseases and genetic diseases, and how to diagnose and treat diseases.
Chapter 8: The digestive system. This chapter explains the structure and function of the digestive system, which includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine and accessory organs (liver, gallbladder and pancreas), as well as the process of digestion and absorption of nutrients.
Chapter 9: The circulatory system. This chapter describes the structure and function of the circulatory system, which includes the heart, blood vessels (arteries, veins and capillaries) and blood (plasma and blood cells), as well as the process of blood circulation (systemic and pulmonary) and gas exchange.
Chapter 10: The respiratory system. This chapter analyzes the structure and function of the respiratory system, which includes the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli, as well as the process of respiration (ventilation and gas exchange).
Chapter 11: The excretory system. This chapter explores the structure and function of the excretory system, which includes the kidneys, ureters, urinary bladder and urethra,

Chapter 12: The nervous system. This chapter investigates the structure and function of the nervous system, which includes the central nervous system (brain and spinal cord) and the peripheral nervous system (sensory and motor neurons), as well as the process of nerve impulse transmission, the types of neurotransmitters and the effects of drugs on the nervous system.
Chapter 13: The endocrine system. This chapter examines the structure and function of the endocrine system, which includes the glands that produce and secrete hormones, such as the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries and testes, as well as the process of hormonal regulation, the feedback mechanisms and the disorders of the endocrine system.
Chapter 14: The immune system. This chapter explains the structure and function of the immune system, which includes the organs and cells that protect the body from foreign invaders, such as the lymphatic system, the thymus, the spleen, the bone marrow, the white blood cells and the antibodies, as well as the process of immune response, the types of immunity (innate and adaptive) and the diseases of the immune system (allergies, autoimmune diseases and immunodeficiency).
Chapter 15: The reproductive system. This chapter describes the structure and function of the reproductive system, which includes the organs and cells that are involved in sexual reproduction, such as the ovaries, fallopian tubes, uterus, vagina, testes, epididymis, vas deferens, prostate and penis, as well as the process of gametogenesis (oogenesis and spermatogenesis), fertilization, pregnancy, childbirth and lactation.
Chapter 16: Genetics. This chapter explores the concepts and principles of genetics, such as genes, chromosomes, DNA, RNA, protein synthesis, genetic code, mutations, gene expression and regulation, genetic engineering and biotechnology.
Chapter 17: Evolution. This chapter discusses the concepts and evidence of evolution, such as natural selection, adaptation, speciation, fossil record, comparative anatomy and molecular biology.
Chapter 18: Ecology. This chapter studies the concepts and applications of ecology, such as ecosystems, biomes, populations, communities, interactions (predation, competition, symbiosis), energy flow (food chains and webs), nutrient cycles (carbon cycle), biodiversity (species richness and evenness), conservation (endangered species) and environmental problems (pollution).

As you can see, Libro Biologia 1 Estrada Polimodal.pdf covers a lot of ground in biology. It is a comprehensive guide that will help you understand how life works at different levels of organization and complexity.
