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. Having only one spouse at a time






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






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






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






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






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






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






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






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






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






11. Of or relating to or occurring in the night






12. Cause responses that alter conditions in the internal environment






13. 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






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






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






16. Second in order of importance






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






18. Yearly activity period - approximately 360 days






19. Any area that an animal defends against other animals






20. When one organism has power over another






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






22. Disposed to attack; militant; assertive; pushing






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






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






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






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






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






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






29. 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






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






31. 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






32. Derived or originating internally






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






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






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






36. Having a daily cycle or occurring every day






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






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






39. 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.






40. 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






41. Derived or originating externally






42. Foe - opponent - adversary






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






44. Plant hormone that stimulates fruit ripening and leaf drop






45. Cessation from or slowing of activity during the winter






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






47. 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






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






49. Willing to submit without resistance to authority






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