OBSERVATION

 

Question 1 was a popular question among the candidates and those candidates who attempted the question performed fairly well. Most candidates could state the components of the axial and appendicular skeletons but quite a number of candidates lost marks due to spelling errors e.g. some candidates wrote skill instead of skull and force limbs instead of fore limbs, a good number of candidates could not spell the sternum and vertebral column correctly.

In stating the functions of the axial and appendicular skeletons most candidates could correctly state most of the functions however, only a few candidates stated that the skeletons serve for storage of certain minerals and so most candidates could not score the full marks.

Many candidates could correctly state the importance of calcium and iron supplements to a pregnant woman but most of the candidates omitted to include that calcium intake aids muscle contraction during labour. Most candidates could state the vitamin associated with absorption of calcium namely vitamin D and could correctly state the sources and deficiency symptoms but lost marks due to spelling errors
