Answer Details
Specimen K (Head of a cock)
(a) Drawing and labelling of five parts of specimen K
The head of a cock is drawn below with five parts clearly labelled: the comb, the eye, the beak, the nostril and the wattle.
(b) One function of each of the labelled parts
| Labelled part | One function |
|---|---|
| Comb | Helps to regulate the body temperature of the bird (heat loss). |
| Eye | For sight / vision. |
| Beak | For picking up feed and drinking water (also for scratching and defence). |
| Nostril | For breathing (respiration) and for smelling. |
| Wattle | Aids temperature regulation and serves as a sign of sex appeal / maturity. |
(c) Two management practices that could be carried out on specimen K
- Debeaking - trimming the tip of the beak to prevent cannibalism, feather pecking and egg eating.
- Dubbing (decombing) or dewattling - trimming the comb and/or wattle to prevent frostbite and injury and to reduce fighting.
Specimen L (Pair of scissors)
(d) One tool that could be used in place of specimen L
A sharp knife could be used in place of the pair of scissors to carry out the management practices on specimen K. (A sharp blade, a scalpel or a beak trimmer would serve the same purpose.)
