Show Answers:

  1. Archaea
    One of two prokaryotic domains, the other being Bacteria
  2. bioinformatics
    The use of computers, software, and mathematical models to process and integrate biological information from large data sets
  3. controlled experiment
    An experiment in which an experimental group is compared with a control group that varies only in the factor being tested.
  4. deoxyribonucleic acid (DNA)
    A nucleic acid molecule, usually a double-stranded helix, in which each polynucleotide strand consists of nucleotide monomers with a deoxyribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T); capable of being replicated and determining the inherited structure of a cell's proteins.
  5. eukaryotic cell
    A type of cell with a membrane-enclosed nucleus and membrane-enclosed organelles. Organisms with eukaryotic cells (protists, plants, fungi, and animals) are called eukaryotes.
  6. genomics
    The study of whole sets of genes and their interactions within a species, as well as genome comparisons between species
  7. inductive reasoning
    A type of logic in which generalizations are based on a large number of specific observations.
  8. hypothesis
    A testable explanation for a set of observations based on the available data and guided by inductive reasoning. A hypothesis is narrower in scope than a theory.
  9. model organism
    A particular species chosen for research into broad biological principles because it is representative of a larger group and usually easy to grow in a lab.
  10. inquiry
    The search for information and explanation, often focusing on specific questions.
  11. prokaryotic cell
    A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles. Organisms with prokaryotic cells (bacteria and archaea) are called prokaryotes
  12. negative feedback
    A form of regulation in which accumulation of an end product of a process slows the process; in physiology, a primary mechanism of homeostasis, whereby a change in a variable triggers a response that counteracts the initial change.
  13. natural selection
    A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
  14. science
    An approach to understanding the natural world.
  15. system biology
    An approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the interactions among the system's parts.
  16. theory
    An explanation that is broader in scope than a hypothesis, generates new hypotheses, and is supported by a large body of evidence.
  17. technology
    The application of scientific knowledge for a specific purpose, often involving industry or commerce but also including uses in basic research.
