  1. 1In which order does the signal for the reflex arc travel?
    1. ARELAY NEURONE to SPINAL CORD to SENSORY NEURONE
    2. BSENSORY NEURONE to SPINAL CORD to MOTOR NEURONE
    3. CSPINAL CORD to SENSORY NEURONE to STIMULUS
    4. DSTIMULUS to MOTOR NEURONE to SPINAL CORD
  2. 2In the lighting circuit in a house, how are lamps usually connected, and what is one reason for this?
    1. APARALLEL - to allow every lamp to have the full voltage supply
    2. BPARALLEL - to share out the voltage equally between the lamps
    3. CSERIES - to allow every lamp to have the full voltage supply
    4. DSERIES - to share out the voltage equally between the lamps
  3. 3When the voltage of the supply is reduced, the voltage across the resistor decreases
    1. AVerdadero
    2. BFalso
  4. 4What factors can effect the resistance of a piece of wire?
    1. Atemperature of the wire
    2. Bmaterial of the wire
    3. Cthickness of the wire
    4. Dlength of the wire
    5. Ewhere the wire is located
  5. 5When the eye is focusing on a nearby object:-
    Structure 6 ([blank_start]the suspensory ligaments[blank_end]) will [blank_start]relax[blank_end], allowing for more light to [blank_start]be refracted[blank_end] into the eye. Then structure 8 ([blank_start]The cilliary muscles[blank_end]) [blank_start]contract[blank_end]     Imagen de la pregunta 5
    1. Athe suspensory ligaments
    2. Bthe optic nerve
    3. Cthe retina
    4. Dthe iris
    5. Ethe cilliary muscles
    6. Frelax
    7. Gbe refracted
    8. Hnot be enetered
    9. Ienter
    10. JThe cilliary muscles
    11. Kthe pupil
    12. Lthe cornea
    13. Mthe lens
    14. Ncontract
  6. 6The change in blood glucose concentration can be detected by organ A. If it releases hormone B into the blood, hormone B will convert glucose to glycogen and the concentration of glucose in the blood will decrease. If it releases hormone C into the blood, hormone C will stimulate organ D to convert glycogen to glucose and the blood glucose concentration will increase.

    NAME ORGAN A AND HORMONES B AND C
    1. AOrgan A - PANCREAS
      Hormone B - GLYCOGEN
      Hormone C - INSULIN
    2. BOrgan A - PANCREAS
      Hormone B - INSULIN
      Hormone C - GLYCOGEN
    3. COrgan A - LIVER
      Hormone B - GLYCOGEN
      Hormone C - INSULIN
    4. DOrgan A - LIVER
      Hormone B - INSULIN
      Hormone C - GLYCOGEN
  7. 7Why is glucose converted to glycogen rather than just kept as glucose in the cells
    1. Aglycogen takes up less space and can therefore be stored more easily
    2. Bglycogen is easier to digest and can therefore speed up digestion
    3. Cglycogen is insoluble and is therefore not in danger of osmosis
    4. Dglucose is bad for the human body and must therefore always be converted into glycogen
  8. 8LABEL THE NEURONES IN THE REFLEX ARC DIAGRAMImagen de la pregunta 8
    1. Asensory neurone
    2. Brelay neurone
    3. Cmotor neurone
  9. 9What is the receptor of pressure and temperature detected in the environment?
    1. AToungue
    2. BSkin
    3. CEye
    4. DNose
    5. EEar
  10. 10LABEL THE EYE DIAGRAM

    give answers without the (ex. tree - correct ex. the tree - incorrect)    Imagen de la pregunta 10
    1. Airis
    2. Blens
    3. Csuspensory ligaments
    4. Doptic nerve
    5. Eretina
    6. Fcornea
