Intro to Bio
Fundamental building blocks of
Living and non-living.
Smallest unit of an element that still retains the element’s properties.
Two or more joined atomsof the same or different elements.
The “molecules of life” are complex carbohydrates, lipids, proteins, DNA, and RNA.
Smallest unit that can live and
on its own or as part of a multicellular organism.
Organized cells and substances that interact in a specialized activity.
Two or more tissues interacting in some task.
A parrotfish eye, for example, is a sensory organ used in vision.
Organs interacting physically, chemically, or both in some task. Parrotfish skin is an organ system with tissue layers, organs such as glands, and other parts.
Individual made of different types of cells.
Cells of most organisms, including this Red Seaparrotfish, are organized as tissues, organs, and organsystems.
Group of single-celled or multicelled individuals of the same species occupying a specified area.
This is a fish population
All populations of all species occupying a specified area.
A community that is interacting with its physical environment. It has inputs and outputs of energy and materials.
All regions of the Earth’s waters, crust, and atmosphere that hold organisms.
Earth is a rare planet; without its abundance of free-flowing water,there would be no life.

to do work.
Substance that is necessary for survival, but that an organism can’t make for itself.
Organisms that make their own food using energy andsimple raw materials from the environment
Organisms that get
by feeding on tissues, wastes, or remains of other organisms.
Obtain energy by breaking down remains and wastes.
Set of processes by which an organism keeps its
Molecule or structure that responds to a
of cells in multicelled species.
Multistep process by which the first cell of a new individual becomes a
from parents to offspring.
Energy Flow Summary
• Usually starts with energy from the sun
• Transfers from one organism to another
• Flows in one direction
• Eventually is lost as heat
Each species is given a unique
(system devised by Carolus Linnaeus).
A type of organism
Group of species that share a unique set of traits
8 Levels of Classification
One system sorts all organisms into one of three domains:
Single- or multicelled
Larger, more complex
(Fungi, Protists ,Plants, Animals)
Smaller, less complex
Single celled to multi-celled colonial
organisms- that are
plants, animals, or fungi
Live in extreme environments
Mental process of judging the quality of information before deciding whether or not to accept it.
The systemic study of nature
How Science Works:
Researchers make and test potentially falsifiable predictions about how the naturalworld works.
Generally, scientific inquiry involves forming a
then making and testing
based on the hypothesis.
A hypothesis that is not consistent with the results of scientific tests is modified or discarded!!
A group of objects or individuals that display or are exposed to a variable under investigation.
A group of objects or individuals that is
to an experimental group
