| Question | Answer |
|---|---|
| what charactersitics distinguish living organisms from nonlivin things? | growth and development, self-regulated metabolism, response to stimuli, and reproduction |
| -surrounds and protects cell-separates cell from encironment | plasma membrane |
| -Codes genetic instructions | DNA |
| -Internal structures for special functions | Organelles |
| -Bacteria and archaea-Single celled organisms-No membrane-bound organelles | Prokaryotic cells |
| -Organelles enclosed by membranes-Nucleus contains DNA | Eukaryotic cells |
| -Increases size and/or number of cells | Biological growth |
| -Changes that take place during an organism’s lifetime | Development |
| -All the chemical activities of the organism | Metabolism |
| -Homeostatic mechanisms regulate and balance the internal environment | Homeostasis |
| -Physical or chemical changes in the internal or external environment-Cause the organism to respond | Stimuli |
| -Low genetic variability | Asexual reproduction |
| -High genetic variability | Sexual reproduction |
| What are the hierarchical levels of biological organization? | molecules, macromlecules, organelle, cells, tissues, organs, organ system, organism, population, community, ecosystem, biosphere |
| -Transmits information from one generation to the next-Contains 4 types of nucleotides-Makes up genes-Codes for proteins | DNA |
| -Chemical and electrical signals | ProteinsHormonesCell signalingNeurotransmitters |
| -Explains changes in populations over time | Theory of Evolution |
| -Processes by which populations change overtime | Evolution |
| -Study of organisms and their evolutionary relationships | Systematics |
| -Science of naming and classifying organisms | Taxonomy |
| -Populations capable of breeding with one another | Species |
| What are the 3 domains and 6 kingdoms of living organisms? | Domains:Bacteria, Archaea, EukaryaKingdoms:Bacteria, Archaea, Protista, Plamtae, Animalia, Fungi |
| -Interactions between environmental conditions and genes-Takes place over many generations-An evolutionary process | Adaptation |
| -Charles Darwin and Alfred Wallace-Applies to populations, not individuals | Natural Selection |
| Darwin’s 4 Observations | -Individuals of a species vary-More offspring are produced than survive-Organisms compete for resources; some are better adapted to succeed-Best-adapted individuals survive to reproduce |
| -Chemical or physical changes in DNA-Can be inherited-Cause genetic variation | Mutations |
| -Process by which populations change over time as a result of selective pressures from changes in environment | Evolution |
| -All the genes in a population | Gene Pool |
| -Make their own food-Transform light energy to chemical energy through photosynthesis | Autotrophs |
| CO2 + water + light → sugars + oxygen | Photosynthesis |
| -use energy stored by producers through cellular respiration | Heterotrophs |
| sugars + oxygen → CO2 + water + energy | cellular respiration |
| -break down wastes and dead organisms | Decomposers (heterotrophs) |
| -draws specific conclusions based on information (facts) | Deductive reasoning |
| -draws general conclusions based on specific observations | Inductive reasoning |
| -The Scientific Method | -Observation-Question or problem-Hypotheses-Testable predictions-Experiments-Analyze data-Conclusions |
| -A tentative explanation for observations *Consistent with facts-Can be tested *Tests can be repeated by others-Can be rejected *Is falsifiable | The Hypothesis |
| -Deductive product of a hypothesis | Prediction |
| -Closely matches experimental group | Control group |
| -Differs from control group in 1 variable | Experimental group |
| -An explanation of the natural world-Based on testable hypotheses-Supported by reproducible observations | Scientific Theory |
