This question was attempted by many candidates and their performance was fairly good. In part
(a)(i) few candidates correctly drew and labelled the female urinogenital system, in (a)(ii) many
candidates correctly defined sexually transmitted diseases and in (a)(iii) many candidates correctly
named sexually transmitted diseases. In part (b) few candidates correctly, state function of the
following parts associated with the neurone(i) axon(ii) myelin sheath (iii) node of ravier (iv)
dendrite.
In part (c) candidates correctly stated ways of preventing the spread of HIV / AIDS.
However, the expected answers were as follows:
2(a)(i) Diagram of female urinogental system
Labels - 8 x1/2= 4 marks

- gonorrhoea
- syphilis
- HIV/AIDS
- Chancroids
- Genital warts
- Genital herpes
- Chlamydia
Spelling must be correct to score.
(b) Function of axon, myelin sheath, node of ranvier and dentrite
Function of axon
carries impulse away from the ell body
Function of myelin sheath
transmission of nerve impulses/insulates axon
Function of ranvier
speeds up transmission of nerve impulses
Function of dendrite
carry impulses to the cell body
(c) Ways of Preventing the spread of HIV!AIDS
abstinence
be faithful to partner
use of condom
sterilization of hypodermic needles
avoid sharing of blades/sharp objects/brushes
avoid deep kissing with strangers
screen blood before transfusion
