1.1 Levels of Organization
Ecosystem- highest structured level in which life is organized, includes biotic and abiotic factors
Community- all organisms living in an area, biotic
Population- interacting group of one species
Organism- individual living organism
Organ System- group of organs working together in a body
Organ- structure made of several tissues to perform a specific function
Tissue- unit of similar cells, perform functions in multicellular organisms
Cell- unit of living matter, separated from environment my membrane
Molecule- a cluster of atoms
DNA- genetic material inherited by organisms

1.2-1.3 The Process of Science
Hypothesis- An educated guess or explanation with reasoning about a experiment or fact
Observation- Notes you take using your senses
Qualitative Observation- An observation made using your senses: ex: smell, color, texture, appearance
Quantitative Observation-An observation made having to do with the numbers: ex: weight, measure, height, length
Inference- A prediction you make using what you know (background information)
Conclusion- Your overall opinion/result using your data tested
Inductive Reasoning- Starting from general and reasoning to specific
Deductive Reasoning- Starting from specific and reasoning to general
Control Groups (+/-)- positive: a control experiment that you know will give you the results you want, negative: a control experiment that you know will give you the opposite result of what you want
Constants- something that stays the same within all variations of an experiment
Data- Information that is collected from an experiment or test
Independent Variable- The variable that keeps going throughout the experiment (ex. time)
Dependent Variable- The data that changes depending on the independent variable
Title- States all that is shown in the graph and all that you are testing

1.4 Evolution, Unity & Diversity
Prokaryote- organism, has cell(s) with no nucleus
Eukaryote- organism, has cells with a nucleus and internal structures
Bacteria- group of prokaryotes, "new"
Archaea- group of prokaryotes, "old," Found in extreamofiles/extreme atmospheres
Eukarya- organism made of eukaryote cells, includes protists, plants, fungi, and animalia
Protists- make own food molecules by photosynthesis
Plants- use photosynthesis, has cells with strong walls made of cellulose
Fungi- decompose remains of dead organisms and absorb nutrients
Animalia- eat other organisms, its cells lack rigid walls, usually motile

1.5 Properties of Life
Order- all organisms show complex organization
Regulation- mechanisms maintain internal environment within limits that sustain life
Growth and Development- each species has its own growth pattern and development characteristics
Energy Utilization- transformation of energy to perform
Response to Environment- all organisms respond to environmental factors
Reproduction- DNA creates precise reproduction, organisms reproduce their own kind
Evolution- reproduction creates ability for species to change over time

1.6 Evolution Explains the unity and diversity of life
Natural Selection- process through which organisms in a species with a favorable trait for survival pass on this trait to their offspring, whereas organisms with unfavorable traits die and don't pass on these traits, resulting in species having traits better geared for survival over time
Heritable Variations- differences that can be passed on
Environmental Factors- elements in the environment that affect a species' chance of survival
Reproductive Success- the success with which an organism reproduces, natural selection favors species with high reproductive success
