Diagram 2 shows a cross section of a human eye. What is the function of X?
to allow reflection of light
to act as a concave lens
to control the size of the pupils
to focus light onto the retina
Why does the taste sense of a person less sensitive if the person is having flu?
the taste buds has become less sensitive
thick mucous prevent food from reaching to the taste buds
the nasal hairs are unable to detect the smell of food
chemicals cannot be detected by the smell receptor

eyes, ears, skin and tongue
eyes, ears, skin, tongue and nose
The diagram below shows the structure of a human eyeball. While looking at an object, the image of the object will form at P. What is the effect on our vision?
the object cannot be seen because P has no light receptors
the object is blur because surface P is not smooth and light cannot be focused
the object is seen in black and white only because P has no cone cells.
the object is seen upside down because there is a curve on the retina at P.
