Down
- 2. a heritable change in the characteristics within a population from one generation to the next; the development of new types of organisms from preexisting types of organisms over time
- 3. organism whose genome has been altered to contain one or more genes from another organism or species
- 5. a group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies
- 7. the process of becoming adapted to an environment; an anatomical, physiological, or behavioral change that improves a population's ability to survive
- 9. the process of obtaining information by using the senses; the information obtained by using the senses
- 10. a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation
- 12. the variety of organisms in a given area, the genetic variation within a population, the variety of species in a community, or the variety of communities in an ecosystem
- 13. a procedure that is carried out under controlled conditions to discover, demonstrate, or test a fact, theory, or general truth
- 14. variable experimental data collected through observation and measurement
- 15. a set of particles or interacting components considered to be a distinct physical entity for the purpose of study
- 17. the maintenance of a constant internal state in a changing environment; a constant internal state that is maintained in a changing environment by continually making adjustments to the internal and external environment
- 20. in biology, the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm
- 24. the scientific study of living organisms and their interactions with the environment
