Bio Ch 1.4 Voc
Biology Chapter 1.4 Vocab / biodiversity is in Sect 1.5
| Question | Answer |
|---|---|
| Science | In biology, the observation, identification, experimental investigation, and theoretical explanation of natural phenomena. |
| model organism | An organism studied by many different researchers so that they can compare their results and determine scientific principles that apply more broadly to other species. |
| scientific method | A series of steps to test the validity of a hypothesis. This approach often involves a comparison between control and experimental groups. |
| Ecology | The study of interactions among organisms and between organisms and their environments. |
| Anatomy | The study of the structure or form of an animal’s body or organs. |
| Physiology | The study of how the structures of an animal’s body function. |
| cell biology | The study of individual cells and their interactions with each other. |
| molecular biology | A field of study spawned largely by genetic technology that looks at the structure and function of the molecules of life. |
| Reductionism | An approach that involves reducing complex systems to simpler components as a way to understand how the system works. In biology, reductionists study the parts of a cell or an organism as individual units. |
| systems biology | A field of study in which researchers investigate living organisms in terms of their underlying networks—groups of structural and functional connections—rather than their individual molecular components. |
| Hypothesis | In biology, a proposed explanation for a natural phenomenon based on previous observations or experimental studies. |
| Prediction | An expected outcome based on a hypothesis that can be shown to be correct or incorrect through observation or experimentation. |
| Testable | With regard to a hypothesis, one that can be shown to be consistent or inconsistent with data that are obtained via experimentation. |
| Falsifiable | With regard to a hypothesis, one that is falsifiable can be shown to be incorrect via additional observations or experimentation. |
| Theory | a broad explanation of some aspect of the natural world that is substantiated by a large body of evidence. Incorporates observations, hypothesis testing, and the laws of other disciplines such as chemistry and physics. A theory makes valid predictions. |
| DNA | is the genetic material and that it is organized into units called genes. |
| Knowledge | The awareness and understanding of information. |
| discovery-based science | The collection and analysis of data without the need for a preconceived hypothesis; also called discovery science. |
| hypothesis testing | A strategy for testing the validity of a hypothesis; also known as the scientific method. |
| control group | The sample in an experiment that is treated just like the experimental group except that it is not subjected to one particular variable. |
| experimental group | The sample in an experiment that is subjected to some type of variation that does not occur for the control group. |
| Repeatable | Refers to the idea that experiments are valid only if the same results are obtained on multiple occasions. |
| hypothesis testing steps 1-5 | 1, observations of natural phenomenon. 2, these observations lead to a hypothesis to explain the phenomenon. 3, experimentation to determine if predictions are correct. 4, data from experiment are analyzed. 5, hypothesis is accepted or rejected. |
| Biodiversity | the variety of life-forms that exist now and existed in the past. |
