- theory
- comprehensive ideas which are broad explanatory power
- homeostasis
- tendency of a system to maintain internal stability
- Plantae
- photosynthetic, autotrophic
- domain
- highest group in taxonomic hierarchy (Eukarya, Bacteria, Archaea)
- eukaryote
- has a nucleus ("true seed")
- deductive reasoning
- establishing specific principles based on general observations
- adaptation
- features that evolved by means of natural selection
- Animalia
- eats other organisms, heterotrophic
- ecosystem
- all living organisms and nonliving factors interacting in a given area
- community
- all living organisms in an ecosystem
- Bacteria
- prokaryote, made of smaller simpler cells, unicellular
- hypothesis
- educated guess/tentative answer to a question
- replication
- repetition of an experiment
- population
- all organisms from one species in an ecosystem
- tissue
- a group of cells with the same function
- Fungi
- decomposes dead matter, digests matter externally then absorbs the nutrients, heterotrophic
- protist
- unicellular eukaryotes
- autotrophic
- makes own food
- species
- organism with common traits that can successfully interbreed
- biotic
- living
- biosphere
- the whole planet
- discovery science
- science based on observations, descriptions
- kingdom
- second highest group in taxonomic hierarchy (domain Eukarya has 3: Animalia, Plantae, Fungi)
- prokaryote
- has no nucleus
- independent variable
- what you change
- natural selection
- heritable variations are exposed to environmental factors that favor the reproductive success of some individuals over others
- Eukarya
- eukaryote, more complex cells than Bacteria and Archaea, can be unicellular or multicellular
- organ
- a group of tissues working together for a specific function
- inductive reasoning
- establishing general principles based on specific observations
- heterotrophic
- eats others
- dependent variable
- the result
- control group
- a group that does not receive a treatment and is being compared to a group that receives it
- cell
- smallest unit of life
- abiotic
- nonliving
- organ system
- a group of organs working together for a common purpose
- Archaea
- prokaryote, made of smaller simpler cells, unicellular
- evolution
- genetic change in a population or species over generations
- organism
- one individual
