A group of two or more atoms bonded together that forms the smallest identifiable unit of life.

A tiny specialized structure inside a cell, made up of molecules.

The basic building blocks of life made of organelles.

A group of similar cells that work together to perform a specific function.

A collection of different tissues joined together in a structural unit to perform a specific function.

Any individual living thing made of organs that work together.

The total number of organisms in a specific area or group.

An interacting group of various populations in a common location.

A community of organisms interacting with each other and their non-living physical environment as a single unit.

The global ecological system made up of all living things on earth.

As complexity increases, new functions and properties are generated

Structure and Function

Purpose(function) can be inferred based on their arrangement(structure)

microscopic, single-celled organism that lacks a nucleus.

Bacteria and Archaea cell

microscopic, single-celled organism that lacks a nucleus.

A single-celled organism that lacks a nucleus or other membrane-bound internal parts.

The theory that genetic information flows in one direction from DNA to RNA, and then to proteins

Law of Thermodynamics

Energy transformations are inefficient and some energy is released as heat

Process to regulate and maintain equilibrium

Positive feedback regulation

a biological process where an initial change in a system is amplified and reinforced, pushing the system further in the direction of the change until a specific goal or endpoint is reached.

Negative feedback regulation

a self-correcting process where a system's output reduces or reverses the original change to return conditions to a stable target level.

species change in ways that are adaptive to their environment

new, genetically distinct species form from existing populations
