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






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






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






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






5. 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






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






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






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






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






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






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






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






13. 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






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






15. Yearly activity period - approximately 360 days






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






17. Derived or originating externally






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






19. 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






20. A cue using the earths magnetic field






21. Orienting or directing homeward or to a destination






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






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






24. When one organism has power over another






25. Cessation from or slowing of activity during the winter






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






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






28. Second in order of importance






29. Any area that an animal defends against other animals






30. 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.






31. Having more than one spouse at a time






32. Having a daily cycle or occurring every day






33. Foe - opponent - adversary






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






35. 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






36. Plant hormone that stimulates fruit ripening and leaf drop






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






38. Having only one spouse at a time






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






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






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






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






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






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






45. Willing to submit without resistance to authority






46. Derived or originating internally






47. Disposed to attack; militant; assertive; pushing






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






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






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