Questions & Vocabulary
| Question | Answer |
|---|---|
| Biology | Scientific study of life |
| Cells | The structural and functional units of life |
| All animals from ants to plants to people, are composed of what? | Cells |
| What are the abilities of a cell? | Can regulate its internal environment, take in and use energy, and respond to its environment. |
| What are some properties of life? | Order, Response to Environment, Reproduction, Growth & Development, Energy Processing, Evolutionary Adaptation, Regulation |
| Reproduction | Organisms reproduce their own kind |
| Order | Life is characterized by highly ordered structures |
| Response to Environment | All organisms respond to environmental stimuli "Venus flytrap rapidly closing its trap in response to a fly landing on it" |
| Energy Processing | Organisms taking in energy and using it to power other activities |
| Growth & Development | Inherited info encoded in DNA controls the pattern of growth and development in all organisms |
| Regulation | Organisms have regulatory mechanisms that maintain a beneficial internal environment " Lizards sunbathe to raise their temps on cold mornings" |
| Evolutionary Adaptation | Adaptation such as the red panda's warmth-providing tail, evolve over generations as individuals with heritable traits that are best suited to their environments have greater reproductive success. |
| Taxonomy | The branch of biology that names and classifies species, arranges species into a hierarchy of broader groups, from genus, family, order, class, and phylum, to kingdom. |
| What is the goal of taxonomy? | To reflect the evolutionary history and relationships of organisms |
| Domains | The highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. Archaea, Bacteria, Eucarya. |
| Domains Bacteria and Archaea both consist of microscopic organisms with ________ . | Simple Cells |
| Organisms with complex cells are called what? | Eukaryotes - Domain Eukarya |
| Protists | A diverse collection of single-celled organisms |
| Plants which produce own food by photosynthesis | Kingdom Plantae |
| Decompose organic wastes an absorb the nutrients into their cells | Kingdom Fungi |
| Animals- Obtain food by eating other organisms | Kingdom Animalia |
| Biosphere | All life on Earth and the places where life exists Ex. Regions of land, bodies of water, lower atmosphere |
| Ecosystem | All organisms in a particular area, as well as the physical components with which life interacts ( soil, water, light) Ex. Forests, Shoreline |
| Community | All the organisms in an ecosystem Ex. Trees, Grass, Animals |
| Population | All individuals of a particular species living in a community |
| Organism | An individual living thing |
| Organs and Organ System | Body parts that perform a specific function |
| Tissue | A group of similar cells performing a specific function |
| Cell | The fundamental structural and functional unit of life |
| Organelle | A membrane enclosed functional structure in a cell |
| Molecule | A chemical structure consisting of two or more units called atoms |
| Science | A way of knowing - an approach to understanding the natural world |
| Data | Recorded observations - the evidence on which scientific inquiry is based |
| Inquiry | A search for information and explanations of natural phenomena |
| Hypothesis | A proposed explanation for a set of observations "If this, Then that" |
| Experiment | A scientific test, often carried out under controlled conditions |
| A scientific ______ is much broader in scope and is supported by a large and usually growing body of evidence . | Theory |
| Independent Variable | Factor that is manipulated by researchers |
| Dependent Variable | Measure used to judge the outcome of the experiment This variable depends on, or is affected by the manipulated variable |
| Controlled Experiment | When an experimental group is compared with a control group |
| The goal of technology is to...? | Apply scientific knowledge for some specific purpose |
| How is science and technology related? | Scientists use new technology in their research, and scientific discoveries often lead to the development of new technologies |
| Evolution | The process of change that has transformed life on Earth from its earliest forms to the vast array of organisms living today |
| Natural Selection | A mechanism for evolution |
