Biology - Ch1
| Term | Definition |
|---|---|
| biology | the scientific study of life |
| evolution | the process of change that has transformed life on earth from its earliest beginnings to the diversity if organisms living today |
| emergent properties | new properties that arise with each step upward in the hierarchy of life, owing to the arrangement and interactions of pars as complexity increases |
| system biology | an approach that attempts to model the dynamic behavior of whole biological systems based on a study of the interactions among the system's parts |
| global climate change | increase in temperature and change in weather patterns all around the planet, due mostly to increasing atmospheric co2 levels from the burning of fossil fuels. the increase in temperature, called global warming, is a major aspect of global climate change |
| eukaryotic cell | a type of cell with a membrane-enclosed organelles. organisms with eukaryotic cells (protists, plants, fungi, and animals) are called eukaryotes |
| prokaryotic cell | a type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles. organisms with prokaryotic cells (bacteria and arcaea) are called prokaryotes |
| dna | a double-stranded, helical nucleic acid molecule, consisting of nucleotide monomers with a deoxyribose sugar and the nitrogenous based adenine, capable of being replicated and determining the inherited structure of the cell's proteins |
| genes | the units of inheritance that transmits information from parent to offspring |
| gene expression | the process by which information encoded in dna directs the synthesis of proteins or, in some cases, rnas that are not translated into proteins and instead function as rnas |
| genome | the entire "library" of genetic instructions that an organism inherits |
| genomics | studying whole sets of genes of a species as well as comparing genomes between species |
| bioinformatics | the use of computational tools to store, organize, and analyze the huge volume of data that results from high-throughput methods |
| negative feedback | accumulation of an end product of a process slows that process |
| positive feedback | an end product speeds up its own production |
| bacteria | one of the two prokaryotic domains, the other being archaea |
| archaea | one of the two prokaryotic domains, the other being bacteria |
| eukarya | the domain that includes all eukaryotic organisms |
| natural selection | evolutionary adaption where the natural environment "selects" for the propagation of certain traits among naturally occurring variant traits in the population |
| science | a way of knowing |
| inquiry | the search for information and explanation, often focusing on specific questions |
| data | recorded observations |
| inductive reasoning | a type of logic in which generalizations are based on a large number of specific observations |
| hypothesis | a tentative answer to a well framed question - an explanation on trial |
| controlled experiment | an experiment in which an experimental group is compared with a control group that varies only in the factors being tested |
| theory | an explanation that is broader in scope than the hypothesis, generates new hypotheses, and is supported by a large body of evidence |
| model organism | a species that is easy to grow in the lab and lends itself particularly well to the questions being investigated |
| technology | the application of scientific knowledge for a specific purpose, often involving industry or commerce but also including uses in basic research |
