NCEA Level 3: Animal Plant Responses

Subject : NCEA
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Period of dormancy - usually seasonal - which growth and development cease and metabolism is greatly reduced






2. The process by which evolution selects for genes that cause individuals to provide benefits to their relatives






3. Reversible growth or turgor movement in response to a non directional stimulus






4. This is a non-directional response to a stimulus or a change in activity rate in response to a change in the intensity of the stimulus






5. The environmental agent that resets the biological clock e.g: change in light - temperature






6. The natural period of the rhythm if there are no external cues.






7. A polygamous mating system involving one female and many males






8. A polygamous mating system involving one male and many females






9. The periodic passage of groups of animals (especially birds or fishes) from one region to another for feeding or breeding






10. When one organism has power over another






11. Derived or originating internally






12. Cause responses that alter conditions in the internal environment






13. A change in an organism's surroundings that causes the organism to react.






14. Second in order of importance






15. Behaviors that have been developed by experience rather than by having them from birth






16. Derived or originating externally






17. Yearly activity period - approximately 360 days






18. Chemical messengers that are manufactured by the endocrine glands - travel through the bloodstream - and affect other tissues






19. To change the start times of a rhythm - but not its period






20. Having more than one spouse at a time






21. Having from birth; occurring naturally rather than being learned






22. A plant hormone that brings about dormancy in buds - mantains dormancy in seeds - and brings about stomatal closing - among other effects.






23. Serves as a navigational cue. Many birds use star patterns and movement for navigation.






24. Of or relating to or occurring in the night






25. Cessation from or slowing of activity during the winter






26. Light receptor pigment in photoperiodism. Pr (red-light absorbing) vs Pfr (infrared light absorbing) In short-day plants - it stops flowering but in long-day plants it induces flowering






27. Special structures that allow living organisms to sense the conditions of their internal or external environment






28. Working together between species or in a species






29. When organisms orient themselves either towards or away from a stimulus






30. A single receptor is used to calculate the direction of a stimulus






31. Of or relating to biological processes occurring at 24-hour intervals






32. Plant that generally requires long nights-- 12 or more hours of darkness to begin the flowering process.






33. This is the growth towards or away from a stimulus coming from one direction. If the movement is towards the stimulus it is positive - if it is away from the stimulus it is negative






34. Having a daily cycle or occurring every day






35. Stimulates cell division and growth of lateral buds. Causes dormant seeds to sprout.






36. Orienting or directing homeward or to a destination






37. When an animal is active around sunrise and sunset.






38. A colored chemical compound that absorbs light - producing color






39. An innate mechanism in living organisms that controls the periodicity of many physiological functions






40. Movement of the whole organism towards or away from a stimulus coming from one direction






41. Foe - opponent - adversary






42. A cue using the earths magnetic field






43. First in order of importance






44. When the amount of random turning is related to the intensity of a stimulus (unorientated response)






45. Mating behaviour in which a number of males and females mates with each other.






46. The period of daylight - specific for any given species - that triggers a long-day or a short-day response in organisms






47. A special case of polymorphism based on the distinction between the secondary sex characteristics of males and females.






48. The lobes of the brain that receive signals from the receptors in the eyes






49. Type of behavior in which an animal sends out stimuli—such as sounds - visual displays - or chemicals—in order to attract a member of the opposite sex






50. The resemblance of an animal species to another species or to natural objects
