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. 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






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






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






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






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






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






7. 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






8. 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






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






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






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






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






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






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






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






16. Yearly activity period - approximately 360 days






17. Disposed to attack; militant; assertive; pushing






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






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






20. Having more than one spouse at a time






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






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






23. 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.






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






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






26. Cessation from or slowing of activity during the winter






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






28. Orienting or directing homeward or to a destination






29. Cause responses that alter conditions in the internal environment






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






31. Period of time during which a plant embryo is alive but not growing






32. Having only one spouse at a time






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






34. Second in order of importance






35. A cue using the earths magnetic field






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






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






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






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






40. Working together between species or in a species






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






42. Derived or originating internally






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






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






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






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






47. Derived or originating externally






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






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






50. 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
