Living things are made of cells, are based on a universal genetic code, obtain and use materials and energy, grow and develop, reproduce, respond to their environment, maintain a stable internal environment, and change over time.
The three major themes in the study of biology are diversity, interdependence, and evolution. Diversity concerns the observation and classification of the many different species of living things on Earth.

The foundation of biology as it exists today is based on five basic principles. They are the cell theory, gene theory, evolution, homeostasis, and laws of thermodynamics.
The first—purely biological—dimension embraces the three main principles variation, heredity, and selection structured in nine key concepts that form the core idea of natural selection.
There are seven characteristics of living things: movement, breathing or respiration, excretion, growth, sensitivity and reproduction.

The eight characteristics of life: adaptation through evolution, cellular organization, growth and development, heredity, homeostasis, reproduction, metabolism, and response to stimuli. All organisms we consider to be living show all eight of these traits.

The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
This division focuses on the study of individual branches of life. There are four primary categories: botany, human biology, microbiology and zoology.
- Evolution. evolution by natural selection is biology’s core unifying theme and can be seen at every level in the hierarchy of life.
- the relationship of structure and function. …

Biology is the natural science that involves the study of life and living organisms. Without biology, it would be difficult to understand the anatomy of humans, animals, and other creatures.
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, regulation, homeostasis, energy processing, and evolution. When viewed together, these nine characteristics serve to define life.
Some examples of non-living things include rocks, water, weather, climate, and natural events such as rockfalls or earthquakes. Living things are defined by a set of characteristics including the ability to reproduce, grow, move, breathe, adapt or respond to their environment.
The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells. All living organisms is made of cells. Although fire needs oxygen to burn, this does not mean it is living.
By definition, cellular organization is the components that make up the cell and how they are arranged inside it. Each component called an organelle, performs a specific function vital for the cell. This page will explore the basic functional components of the cell and cell shape and its size.
Branches of biological study include microbiology, physiology, ecology and genetics; subdisciplines within these branches can include: microbial physiology, microbial ecology and microbial genetics.
Three unifying themes found in biology are diversity and unity of life, interdependence of organisms, and evolution of life.
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. … Parts of a cell. A cell is surrounded by a membrane, which has receptors on the surface.

the idea the writer wishes to convey about the subject—the writer’s view of the world or a revelation about human nature. To identify the theme, be sure that you’ve first identified the story’s plot, the way the story uses characterization, and the primary conflict in the story.
Themes and Meanings The central theme of Betrayal is, as its title indicates, deception and betrayal in human relationships.
The cell (from Latin cellula ‘small room’) is the basic structural and functional unit of life. Every cell consists of a cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. … There are four main tissue types in the body: epithelial, connective, muscle, and nervous. Each is designed for specific functions.
A cell is defined as the smallest unit of an organism with a nucleus. An example of a cell is a unit in the tissue of an animal muscle. Any of various devices, or units within such devices, that are capable of converting some form of energy into electricity.

Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies–human medical research, plant research, animal research, environmental system research–at the cellular level or the ecosystem level or anywhere in between.
Biology examines the structure, function, growth, origin, evolution, and distribution of living things. It classifies and describes organisms, their functions, how species come into existence, and the interactions they have with each other and with the natural environment.
The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
