This is question was fairly attempted by the candidates. In question 4(a), most
candidates could name specimens N(fish scales), O(feathers) and P(hoot). |
Also, many candidates were able to list products that can be made from specimen M(milk).
However, majority of the candidates were unable to make a labelled drawing 8 - 10cm long of a
longitudinal section of specimen Q(udder) as observed with the aid of specimen S(handlens).
Further to this, most candidates could not state the economic uses of specimens O(feathers) and
P(hoot).
The expected answers include:
