"Biology is the scientific study of life."
The study of life and living organisms, including their structure, function, and behavior.
Cell Theory: The notion that cells are the basic unit of living organisms is one of the most fundamental principles of biology.
Evolution: The theory of evolution explains how living things change and adapt over time. This is a critical concept in biology that has been extensively researched and challenged throughout history.
Genetics: The study of heredity and variation in living organisms, including the mechanisms behind these processes, is central to modern biology.
Ecology: This field deals with how living organisms relate to their environment and how they interact with one another. Understanding the fundamental tenets of ecology is crucial to understanding the complexities of natural systems.
Microbiology: This area of study deals with the properties and behavior of microscopic organisms like bacteria, viruses, and fungi.
Anatomy and Physiology: Anatomy explores the structure of living organisms, while physiology examines their functions.
Biochemistry: This discipline focuses on the chemical processes within living organisms and the chemical reactions necessary for life.
Biotechnology: The application of scientific and engineering principles to the manipulation of living organisms is a key area of research today.
Neuroscience: This field of study focuses on the structure and function of the nervous system and how it affects behavior and cognition.
Immunology: The study of how the immune system and body responses to foreign objects or diseases.
Biostatistics: Includes the methods and processes used to collect and analyze data in biology.
Anatomy: The study of the structure and internal workings of living organisms.
Physiology: The study of how living organisms function and perform various biological processes like respiration, digestion, and circulation.
Zoology: The study of animal life, including animal behavior, genetics, and ecology.
Botany: The study of plant life, including plant structure, growth, and reproduction.
Evolution: The study of the origin and development of living organisms over time.
Microbiology: The study of microorganisms such as bacteria, viruses, and fungi.
Cell Biology: The study of the smallest unit of life, the cell, including its structure and function.
Genetics: The study of how traits are inherited from one generation to another and how genes work.
Ecology: The study of how organisms interact with each other and their environment.
Biochemistry: The study of chemical processes within living organisms.
"All organisms are made up of cells that process hereditary information encoded in genes."
"Hereditary information encoded in genes can be transmitted to future generations."
"Another major theme is evolution, which explains the unity and diversity of life."
"Energy processing allows organisms to move, grow, and reproduce."
"All organisms are able to regulate their own internal environments."
"Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations."
"Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use."
"Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the world around them."
"Life on Earth emerged more than 3.7 billion years ago."
"Life on Earth is immensely diverse."
"Prokaryotic organisms such as archaea and bacteria..."
"Eukaryotic organisms such as protists, fungi, plants, and animals..."
"These various organisms contribute to the biodiversity of an ecosystem..."
"They play specialized roles in the cycling of nutrients and energy through their biophysical environment."
"It is a natural science with a broad scope."
"All organisms are made up of cells that process hereditary information encoded in genes."
"All organisms are able to regulate their own internal environments."
"Evolution explains the unity and diversity of life."
"Energy processing allows organisms to move, grow, and reproduce."
