  1. 1What is Homeostasis?
    1. AThe movement of water into and out of cells.
    2. BThe regulation of internal conditions in a cell or organism to maintain optimal conditions for function.
    3. CThe fusion of gametes.
    4. DA process of destroying pathogens in the body.
  2. 2Internal conditions that are controlled include: water content, body temperature and blood glucose concentration.
    1. ATrue
    2. BFalse
  3. 3[blank_start]Receptors[blank_end] detect stimuli in the external or internal environment. (Changes in the environment).
    1. AReceptors
    2. BReceptor Cells
    3. CStimulus
    4. DSynapses
    5. ENeurones
  4. 4All control systems in the body have the following features:
    1. AReceptors
    2. BCoordination Centres
    3. CNeurones
    4. DEffectors
    5. ESynapses
  5. 5The automatic control systems may involve nervous of chemical responses.
    1. ATrue
    2. BFalse
  6. 6How does the nervous system work?
    1. AStimulus- receptor- sensory neurone- coordinator(CNS)- motor neurone- effector- response.
    2. BReceptor- stimulus- sensory neurone- coordinator(CNS)- motor neurone- effector- response.
    3. CStimulus- receptor- motor neurone- sensory neurone- coordinator(CNS)- effector- response.
    4. DStimulus- receptor- sensory neurone- motor neurone- coordinator(CNS)- effector- response.
  7. 7Reflex actions are not automatic/rapid and therefore involve the conscious parts of the brain.
    1. ATrue
    2. BFalse
  8. 8How many different types of neurones do reflexes involve?
    1. A3
    2. B4
    3. C2
    4. D5
  9. 9What do reflex actions do?
    1. AControl everyday bodily functions e.g. breathing and digestion.
    2. BHelp you avoid danger.
    3. CMove your muscles and limbs.
  10. 10The main stages of a reflex arc are:
    1. AStimulus- receptor- sensory neurone- relay neurone- motor neurone- effector- response.
    2. BStimulus- receptor- sensory neurone- motor neurone- relay neurone- effector- response.
    3. CReceptor- stimulus- sensory neurone- relay neurone- motor neurone- effector- response.
    4. DStimulus- receptor- sensory neurone- relay neurone- motor neurone- response- effector.
