  • Endocrine system
  • Skeleton/musculative
  • Brain
  • Nervous system

8. Who devised the term Homeostasis?

  • Walter Cannon
  • Albert Einstein
  • Claude Bernard
  • Charles Darwin

9. What is intrinsic regulation?

  • Slow, whole body response from one tissue type or organ
  • Fast, local response from one tissue type or organ
  • Fast, whole body response from one tissue type or organ
  • Slow, local response from one tissue type or organ

10. What are avoiders?

  • maintaining internal state by avoiding external change
  • Internal state is different to external environment
  • internal state matches external environment
  • internal state matches external environment

11. How does the Blue Crab compensate for low salt?

  • increases internal ammonia levels
  • decreases internal ammonia levels
  • increases internal salt levels
  • decrease internal salt levels

12. What is the advantage of homeostasis?

  • Allows only mammals to exploit wider ranges of environment
  • Allows all animals to exploit wider ranges of environment
  • Allows some animals to exploit wider ranges of environment
  • Allows no animals to exploit wider ranges of environment

13. What is the difference between control systems and maintenance systems?

  • There is no difference
  • Control systems regulate indirectly, maintenance systems regulate directly
  • Control systems regulate directly, maintenance systems regulate indirectly
  • Control systems regulate indirectly, maintenance systems don't regulate at all

14. What is extrinsic regulation?

  • Fast response through the whole body via interactions between organs
  • Fast response through the whole body via interactions between organs
  • Slow response through the whole body via interactions between organ systems
  • Slow response through the whole body via interactions between organ systems

15. What is acclimatisation?

  • Adaptation that alters negative feedback quickly
  • Adaptation that alters positive feedback quickly
  • Adaptation that alters negative feedback gradually
  • Adaptation that alters positive feedback gradually

16. What does extracellular fluid contain?

  • O2, Nutrients, H2O, Wastes, By-Products
  • O2, Nutrients, By-Products, Glucose
  • O2, Nutrients, H2O, Wastes, Plasma
  • O2, Nutrients, NH3, Wastes, By-Products

17. What are conformers?

  • maintaining internal state by avoiding external change
  • internal state matches external environment
  • maintaining constant internal state
  • Internal state is different to external environment

18. What is negative feedback?

  • physiological response in the opposite direction to the detected change
  • physiological response in the same direction to the detected change
  • metabolic response in the opposite direction to the detected change
  • metabolic response in the same direction to the detected change

19. What is enantiostasis?

  • Changing homeostasis by changing a physiological variable to compensate for change in another
  • Changing homeostasis by changing a metabolic variable to compensate for change in another
  • Maintaining homeostasis by changing a physiological variable to compensate for change in another
  • Maintaining homeostasis by changing a metabolic variable to compensate for change in another
