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. Derived or originating externally






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






3. A cue using the earths magnetic field






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






5. Plant that generally requires short nights-- less that 10-12 hours of darkness to begin the flowering process.






6. When one organism has power over another






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






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






9. Located in the brain; secretes hormone melatonin; in some species - it regulates the biological clock and biorhythms






10. A biological clock that enables a migrating bird or insect to fly using the sun and continuously adjust its angle to the sun while flying.






11. Aggressive or defensive social behavior (fighting - fleeing - submitting) between individuals of the same species






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






13. Foe - opponent - adversary






14. Plant hormone that stimulates fruit ripening and leaf drop






15. Having only one spouse at a time






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






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






18. Cause responses that alter conditions in the internal environment






19. Derived or originating internally






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






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






22. Cessation from or slowing of activity during the winter






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






24. 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






25. Willing to submit without resistance to authority






26. Yearly activity period - approximately 360 days






27. Second in order of importance






28. Diagram showing the periods of activity and rest of an organism over a number of twenty four hour periods so that trends in activity can be identified






29. Any area that an animal defends against other animals






30. A hormone that promotes seed and bud germination - stem elongation - and leaf growth; stimulate flowering and development of fruit; affect root growth and differentiation






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






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






33. Disposed to attack; militant; assertive; pushing






34. Prolonged relationship between male and female - associated with joint parental care






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






36. 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






37. Having a daily cycle or occurring every day






38. 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






39. Period of dormancy - usually seasonal - which growth and development cease and metabolism is greatly reduced






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






41. 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






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






43. Having more than one spouse at a time






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






45. First in order of importance






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






47. Of or relating to or occurring in the night






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






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






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