B [1]
Eagle (bird) has feathers. Lizard has scales, earthworm has moist skin, fish has scales.
B [1]
Vertebrates have backbone; invertebrates do not.
B [1]
Rock is non-living. Bacteria, fungus, insect are living.
C [1]

Section B (12 marks)

[2] Any two: flowering / non-flowering; by size; by where they grow (land/water); by type of leaves.
Marking: 1 mark per correct grouping.
[2] Vertebrate has backbone; invertebrate does not. (1 mark each side or 2 for clear difference)
[2] Conductors: iron, copper (or steel); insulator: rubber (or plastic, wood). 1 mark for two conductors, 1 for insulator.
[2] Living: fish / water plant; non-living: stone / water (if object). 1 mark each.
[2] Examples: magnetic/non-magnetic; transparent/opaque; hard/soft; conductor/insulator. 1 mark each.
[2] Body covering (feathers, scales, skin, shell) helps identify animal group and their adaptations. 1 for idea, 1 for usefulness.

Section C (28 marks)
