| Question | Answer |
|---|---|
| Renewable resource and example | can replenish itself within a lifetime, ex: water, trees |
| Nonrenewable resource and example | will eventually run out, ex: coal, oil |
| Abiotic and give an example | nonliving thing, ex: rocks, wind, water |
| Biotic and give an example | living thing, ex: grass, trees, animals |
| Natural selection | occurs in nature; survival of the fittest |
| Artificial selection | humans manipulate genetics to produce what they want |
| Name and explain the ranges from the chart | Optimal range (top; where things are thriving); Zone of physiological stress (downslope); Zone of intolerance (no tolerance for conditions that exist) |
| Organize the levels from smallest to largest | organism, population, community, ecosystem, biosphere |
| Psuedoscience and give three examples | doesn't follow scientific principles, ex: Mind reading, alchemy, astrology, palm reading |
| What are the steps for the scientific method? | 1) Come up with a question, 2) Hypothesis, 3) Experiment, 4) Analysis of the data, 5) Make a conclusion, 6) Determine if the hypothesis is supported |
| Variable | thing that is changed |
| Experimental group | receives the variable |
| Controlled group | is left alone |
| What are the 3 phases of matter? | solid, liquid, gas |
| blind experiment | scientist knows what is going on, the experimental group does not |
| double blind experiment | neither the experimental group nor the scientist knows what is going on |
| What does the double blind experiment reduce? | bias |
| Voc. Matching | |
| What starts as one population and splits into 2? | Divergent evolution |
| What goes from 2 populations and evolves into 1? | Convergent evolution |
| when two species spend enough time together they start to look like each other | Coevolution |
| When over a long period of time enough mutations take place for a new species to emerge | Speciation |
| Small advantageous mutations that have accumulated over countless generations | Evolution |
| competition occurs within members of the same species | Intraspecific competition |
| competition occurs between two different species | interspecific competition |
| Plays the greatest role in determining an organisms range; too much or too little, animals need specific things | critical factor |
| specific gene traits that control adaptations | Inheritance |
| When both organisms benefit | Mutualism |
| When one organism benefits and the other is neither harmed nor helped | commensalism |
| when one organism benefits and the other is harmed | parasitism |
| nature should exist for its own sake regardless of human needs | Ecocentrists |
| Human centered | Anthropocentrists |
| Biological community and its surrounding physical environment | Ecosystem |
| a specific area where an organism inhabits | Niche |
| Trait that allows a species to survive more easily and reproduce | Adaptation |
| A particular environment where an organism can live | Habitat |
| all conditions that surround living organisms | Environment |
| concepts and ideas from multiple fields of study | Interdisciplinary |
| degradation or an undesired change in soil, air or water that affects the health of living things | Pollution |
| began with a public awakening to threats of pollution and toxic chemicals to humans and other species | Modern environmentalism (Rachel Carson) |
| explores issues ad problems all over the entire world not just a local community | Global environmentalism |
| area that belongs to no individual and is shared by the entire society | Commons |
| the greater the demand for something the higher the price | Supply & Demand |
| does the risk out way the benefit? Is it worth the risk | Risk Analysis |
| measurement of a persons resource use | Ecological footprint |
| when human needs are met so that the population can survive indefinitely | sustainability |
| Write out voc. | |
| Close system | nothing enters or leaves the earth in large quantities |
| Biodiversity | the number of different species present in an ecosystem |
| Developed country | High income, higher life span, lower population growth |
| Developing country | Low income, lower life span, higher population growth |
