Composed of electrons, protons, & neutrons

atoms

Union of two or more atoms of the same OR different elements

molecules

The structural & functional unit of all living things

cell

A group of cells with a common structure & function

tissues

Composed of tissues functioning together for a specific task

organ

Composed of several organs working together

organ system

An individual; complex individuals contain organ systems

organism

Smallest taxonomic level

species

Organisms of same species in a particular area

population

Interacting populations in a particular area

community

A community plus the physical environment

ecosystem

Regions of the Earth’s crust, waters, & atmosphere inhabited by living things

biosphere

State the hierarchy of life in order please. highest to lowest)

Biosphere → Ecosystem → Community → Population → Organism → Organ System → Organ → Tissue → Cell → Molecule → Atom

When a new property builds upon another below it; ex. the hierarchy of life

emergent properties

Which is NOT one of the 5 characteristics of life?

innate survival instincts

the sum of all chemical reactions in a cell/organism

some release energy, some require energy

metabolism

A state of biological blance

homeostasis

The activities done in response to the environment

behaviors

Being able to ____ helps organisms be better to function in a particular environment.

adapt

Adaptations due to genetic differences in a population over time leads to ____

evolution

the study of grouping organisms into categories in order to organize the variety of life

taxonomy

What are the three domains?

Bacteria, Archaea, Eukarya

Largest taxonomic level

domain

bacteria.

bacteria

extremophiles, lovers of extreme environments

archaea

What four kingdoms are within Domain Eukarya?

Animalia, Fungi, Protista, Plantae

You, me, dogs, cats, that one groundhog named Phil

Animalia

Mushrooms, mold

Fungi

Amoeba, algae, seaweed

Protista

Plants

Plantae

What order do these terms follow for organism classification?

family, order, species, phylum, genus, class

phylum, class, order, family, genus, species

Scientific names using Genus species

binomial nomenclature

What is the correct way to present genus species names?

capitalize Genus, lower case species, italicize

what scientific investigation typically follows

scientific method

What are the steps to the Scientific Method in order?

observation → hypothesis → experimentation → conclusion

observation

educated prediction; testable; ex. “if…then…”

hypothesis

What the investigator changes for an experiment

Independent Variable (experimental variable)

What’s measured, depends on the changing variable

Dependent Variable (responding variable)

DRY-MIX stands for?

Dependent, Responding, Y-axis, Manipulated, Independent, X-Axis

What is DRY-MIX used for?

Graphing variables

A test group that does not have the conditions other groups are exposed to

control group

conditions that are kept the same in all experimental groups

constants

backed by many experiments; how or why something happens

scientific theories

predict what will happen under certain conditions; backed by math

scientific laws
