36 terms
Terms | Definitions |
|---|---|
 discovery science | science based on observations, descriptions |
| inductive reasoning | derives general principles from a large number of specific observations (logic behind discovery science) |
| hypothesis-based science | science based on experimentation |
| deductive reasoning | derives specific principles from general observations (logic behind hypothesis based science) |
| theory | explains many observations and is supported by lots of evidence; generate new hypotheses |
| definition of life | 1. order/organization, 2. regulation, 3. growth and development, 4. energy utilization and transformation, 5. response to environmental stimuli, 6. reproduction via DNA replication, 7. evolution |
| 1. observation, 2. question, 3. hypothesis, 4. prediction, 5. experiment, 6. conclusion | steps in scientific method |
| biosphere, ecosystem, community, population, organism, organ system, organ, tissue, cell | order of physical scale of biology/ hierarchy of scale |
| domain (taxon), kingdom | order of taxonomic hierarchy |
| Eukarya, Bacteria, Archaea | the domains |
| Animalia, Plantae, Fungi | the kingdoms of domain Eukarya |
| independent variable | what you change/ control in an experiment |
| dependent variable | the result in an experiment |
| replication | repetition of an experiment |
| biotic | living |
| abiotic | nonliving |
| biosphere | #1 on the physical scale of biology/ hierarchy of scale (i.e. earth) |
| biome | #2 on the physical scale of biology/ hierarchy of scale (i.e. open ocean) |
| community | #3 on the physical scale of biology/ hierarchy of scale, all living things interacting in one area, (i.e. all plankton, fish, sharks, whales in open ocean) |
| population | #4 on the physical scale of biology/ hierarchy of scale, all individuals of a single species interacting in one area (i.e. all great white sharks in open ocean) |
| individual organism | #5 on the physical scale of biology/ hierarchy of scale (i.e. Abel the shark) |
| organ system | #6 on the physical scale of biology/ hierarchy of scale (i.e. Abel's digestive system) |
| organ | #7 on the physical scale of biology/ hierarchy of scale (i.e. Abel's stomach) |
| tissue | #8 on the physical scale of biology/ hierarchy of scale (i.e. Abel's stomach muscle |
| cell | #9 on the physical scale of biology/ hierarchy of scale |
| molecule | #10 on the physical scale of biology/ hierarchy of scale |
| atom | #11 on the physical scale of biology/ hierarchy of scale |
| bacteria, archaea | prokaryotes (domains) |
| prokaryotes | very small, simple cells, no organelles |
| eukarya | cells w/ nucleus, have organelles (a domain) |
| protist | unicellular |
| heterotrophs | eat other things, cannot make their own food |
| autotrophs | self-supply food, make their own food |
| animalia | ingest food (a kingdom of domain Eukarya) |
| fungi | digest food externally, then absorb it (a kingdom of domain Eukarya) |
| plantae | make own food by photosynthesis (a kingdom of domain Eukarya) |
