Biology - ✔️✔️the scientific study of life (Survey of the diversity of life on earth)
Fundamental principle is evolution
Some properties of life (only eden ever gives responses related to relationships) - ✔️✔️-
Order
-Energy processing
-Evolutionary adaptation
-Growth and development
-Responses to the environment
-Regulation - body temperature, blood flow
-Reproduction
Reductionism - ✔️✔️from complex system to simpler ones
-Biologists today complement reductionism with systems biology, the exploration of a
biological system by analyzing the interactions among its parts
The Biosphere - ✔️✔️the entire population of Earth inhabited by life; the sum of all the
planet's ecosystems
An ecosystem - ✔️✔️consists of all the living things in a particular area, along with all the
nonliving components of the environment with which life interacts, such as soil, water,
atmospheric gases, and light

tissue - ✔️✔️-is a group of cells that work together, performing a specialized function
cell - ✔️✔️-life's fundamental unit of structure and function
Some organisms are unicellular, which performs all functions of life. While some
organisms are multicellular and have a division of labor among specialized cells

-Two or more atoms held together by covalent bonds
Emergent properties - ✔️✔️-new properties that arise with each step upward in the
hierarchy of life, owing to the arrangement and interactions of parts as complexity
increases
Ecology - ✔️✔️-The study of how organisms interact with each other and their
environment
-Survey of the diversity of life on earth
Exploration of ecological relationships
Evolution - ✔️✔️-Underlying process that accounts for the diversity of life on Earth
-It is the process of change that has transformed life on Earth from its earliest
beginnings to the diversity of organisms living today
-Enables us to understand how organisms vary with their environment
-Evolution explains unity and diversity
Adaptation - ✔️✔️-is an inherited characteristic of an organism that enhances its survival
and reproduction in a specific environment
-Variation within a species, some of this variation is heritable
Synthesis - ✔️✔️-interactions between living organisms and their coevolution
