| Question | Answer |
|---|---|
| how is Ecology helping us? | This helps us evaluate environmental issue, such as the causes and consequences of global climate changes |

| what is the modern term for what Darwin call "Descent with modification? | evolution |
| observation, where _________ and ________ among _________ occurs following the conculsion | natural selection overproduction and competition and individual variation in conculsion unequal reproductive sucess (Natural selection) |
| natural selection | a process in which organisms with certain inherited characteristics are more likely to survive and reproduce than have orgnaisms with other chacteristics different reproductive sucess |
| observation 1 over production and competition | any population of a species has the potential to produce far more off spring than the environment can possibly support with avaible recourse such as food and shelter. this overproduction leads to competition among the varying individual limits |
| observation 2 individual vartion | no two individuals in a poluation are exactly alike. |
| conclusion unequal reproductive sucess | in the struggle for existence those individual, with traits best suited to local enviroment will, on average have greatest reporductive sucess. |
| artificial selection | evidence for the power of unequal reproduction |
| what mechanisms did DArwin propose for evolution? | natural selection |
| what three-word phrase summarizes this mechanism? | unequal reprodutive sucess |
| science | any method of learning about the natural world that follows the scientic method see discovery science, hypothesis-driven science |
| discovery science | the process of scienctific in quiry that focueses on describing nature see also hypotheiss-driven science |
| hypothesis-driven scinece | the process of scientific inquiry that uses the steps of scientific method to answer questions about nature see also discovery scienfitic method. |
| theory | a broad and comprehensive statement about hte world that is supported by the accumulation of great deal of verifiable evidence |
| what way does modern genetic engineering depend on common ancestry shared by all of life on earth? | genetic engineering is made possible by the fact that all life uses chemically indetical DNA, a result of our evolution from a common ancestor |
| what are the steps to scientifc method? | observation question, hypothesis, prediction, experement revise or repeat |
| controlled experiement | an experiment of this type is designed to compare an experiemental group with a control group |
| DNA technology | methods used to study or manipulate genetic material |
| a biosphere is to ecosphere as a ______ is to kingdom | domain |
| is composed of multiple cells a characteristic of all living organisms. True or Flase? | Flase because not all cells are composed of multiple cells. |
| Bacteria | a icroscopic, simple, nucleus-free organism found growing in a riverbed |
| kuarya/animalia | a thimble- sized organism that feeds on algae growing in a pond |
| Eukarya/fungi | an inch tall organism gorwing on the forest floor that consumes material from dead leaves |
| eukarya/ plantae | a foot-tall organisms capable of producing its own food from sunlight |
| hypotheses usually are narrow in scope; theories have broad explanatory power. true or flase? | True |
