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






2. A group or system in which positions of power are ranked






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






4. Derived or originating internally






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






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






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






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






9. Any area that an animal defends against other animals






10. First in order of importance






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






12. Orienting or directing homeward or to a destination






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






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






15. 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






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






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






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






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






20. Working together between species or in a species






21. Plant hormone that stimulates fruit ripening and leaf drop






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






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






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






25. Substance produced in the tip of a seedling that stimulates cell elongation






26. Having only one spouse at a time






27. Having a daily cycle or occurring every day






28. Disposed to attack; militant; assertive; pushing






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






30. When one organism has power over another






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






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






33. Yearly activity period - approximately 360 days






34. Having more than one spouse at a time






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






36. Derived or originating externally






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






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






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






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






41. Second in order of importance






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






43. Cause responses that alter conditions in the internal environment






44. Foe - opponent - adversary






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






46. Cessation from or slowing of activity during the winter






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






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






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






50. A cue using the earths magnetic field
