It needs air, sunlight and water to remain alive.
It will look the same as before.
It will wilt and may even die.
The potted plant is an artificial one.
Her knee will jerk (move).
She is responding to an external stimulus.
Unlike animal A, a butterfly does not have feathers.
Both are animals which have feathers. This means they are birds.
A: swallow (Accept any other bird that can fly as the answer.)
B: penguin (Accept any other bird that cannot fly as the answer.)
• Both are edible fruit.
• Both have many tiny black seeds which can be eaten together with the flesh.
• The flesh of the kiwi fruit is green or yellow but the flesh of the dragon fruit is white
or dark pink.
• The skin of the kiwi fruit is hairy while the skin of the dragon fruit is smooth with
some protrusions.
They are mould.
The cupboard had air, water (from the moisture in the air) and warmth. As such, mould
started to grow on the leather handbag since leather is a natural material.
His heart and lungs could have been hurt.
The skull protects the brain.
It is the human muscular system.
The seeds germinated and grew into young seedlings because the necessary conditions
of air, water and warmth were present.
It starts to make its own food in stage 3.
It obtains food from its seed leaves.
It has a weak stem, so it twines around a support as it grows upwards.
It is the morning glory plant. (Accept any other reasonable answers.)
The liquid level in the glass tube would decrease because the liquid contracted when
cooled.
The liquid level in the glass tube would increase because the liquid expanded when
heated.
