1
Question 1
Mei Ling menguji empat jenis kertas untuk mengetahui kertas yang paling banyak menyerap air. Dia menuang 50 mℓ air ke atas setiap jenis kertas yang sama saiz. Rajah 1 menunjukkan keputusannya. Apakah pemboleh ubah bergerak balas dalam penyiasatan ini?Mei Ling tests four types of paper to find out which paper absorbs the most water. She pours 50 mℓ of water on each piece of paper of the same size. Diagram 1 shows her results. What is the responding variable in this investigation?
Show answerHide answer
B
The responding variable is what we measure and it changes because of the manipulated variable. Mei Ling measures the water absorbed. The type of paper is the manipulated variable; the paper size and the 50 mℓ of water are kept the same.

Question 2
Aiman terpijak duri dan serta-merta menarik kakinya. Bahagian manakah yang mengawal tindakan refleks ini?Aiman steps on a thorn and pulls his foot back at once. Which part controls this reflex action?
Show answerHide answer
C
A reflex action is quick and happens without thinking. It is controlled by the spinal cord, so the signal does not have to go all the way to the brain first.

Question 3
Mikroorganisma Y hidup di dalam kolam. Y mempunyai klorofil dan membuat makanannya sendiri melalui fotosintesis. Apakah Y?Microorganism Y lives in a pond. Y has chlorophyll and makes its own food by photosynthesis. What is Y?
Show answerHide answer
A
Algae are plant-like microorganisms: they have chlorophyll and make their own food. Fungi absorb nutrients from the object they live on, protozoa move to find food, and viruses live only inside other living things.
4
Question 4
Situasi manakah yang menunjukkan persaingan antara haiwan daripada spesies yang sama?Which situation shows competition among animals of the same species?
Show answerHide answer
A
Both peacocks are the same species and they compete for a mate, so this is intraspecies competition. The eagle and owl are different species (interspecies competition); a cat chasing a rat is predator and prey; the bee takes food from a flower and does not compete.
5
Question 5
Aktiviti manakah ialah contoh pemeliharaan haiwan dan tumbuhan?Which activity is an example of preservation of animals and plants?
Show answerHide answer
D
Preservation keeps animals and plants in their original, balanced state, for example by law and by protected areas such as forest reserves. Replanting, turtle hatcheries and rehabilitation centres bring things back to natural conditions, which is conservation.

Question 6
Sebuah kereta mainan dilancarkan dengan daya yang sama di atas empat permukaan, P, Q, R dan S. Jadual menunjukkan jarak yang dilalui sehingga kereta itu berhenti.
Permukaan manakah yang mempunyai daya geseran yang paling besar?A toy car is launched with the same force over four surfaces, P, Q, R and S. The table shows the distance the car travels before it stops. Which surface has the greatest frictional force?
| Permukaan / Surface | P | Q | R | S |
|---|---|---|---|---|
| Jarak / Distance (cm) | 120 | 45 | 80 | 30 |
Show answerHide answer
D
The greater the friction, the sooner the car is slowed down and stopped. Surface S stops the car after only 30 cm, the shortest distance, so S has the greatest frictional force.
7
Question 7
Sebuah bot kawalan jauh bergerak sejauh 90 m dalam masa 15 s. Berapakah kelajuan bot itu?A remote-control boat travels 90 m in 15 s. What is the speed of the boat?
Show answerHide answer
C
Speed = distance / time = 90 m / 15 s = 6 m/s. 0.17 comes from dividing time by distance the wrong way round.
8
Question 8
Udang segar disimpan pada suhu 0 °C dan ke bawah di dalam peti sejuk beku. Faktor pertumbuhan mikroorganisma yang manakah diubah oleh kaedah ini?Fresh prawns are kept at 0 °C and below in a freezer. Which growth factor of microorganisms is changed by this method?
Show answerHide answer
B
Freezing makes the temperature too low for microorganisms to grow. The air, nutrients and acidity are not changed by a freezer.
9
Question 9
Empat jenis bahan dikambus di dalam tanah lembap selama 8 minggu. Jadual menunjukkan jisim setiap bahan sebelum dan selepas itu.
Pernyataan manakah yang disokong oleh data itu?Four materials are buried in damp soil for 8 weeks. The table shows the mass of each material before and after. Which statement is supported by the data?
| Bahan / Material | Sebelum / Before | Selepas / After |
|---|---|---|
| Kulit pisang / Banana peel | 80 g | 12 g |
| Beg plastik / Plastic bag | 20 g | 20 g |
| Surat khabar lama / Old newspaper | 60 g | 25 g |
| Balang kaca / Glass jar | 300 g | 300 g |
Show answerHide answer
C
The banana peel lost 68 g out of 80 g (about 85%), the newspaper only 35 g out of 60 g (about 58%), so the peel decomposed more. The plastic bag and the glass jar did not lose any mass, so they are non-biodegradable. A material is biodegradable when its mass decreases because microorganisms decompose it; it does not need to disappear completely.

Question 10
Rajah 2 menunjukkan kedudukan Matahari, Bumi dan Bulan pada satu malam apabila berlaku gerhana Bulan. Aisyah berkata, "Gerhana Bulan berlaku setiap bulan kerana Bulan mengelilingi Bumi sekali dalam sebulan." Mengapakah Aisyah salah?Diagram 2 shows the positions of the Sun, Earth and Moon on a night when an eclipse of the Moon happens. Aisyah says, "An eclipse of the Moon happens every month because the Moon goes round the Earth once a month." Why is Aisyah wrong?
Show answerHide answer
B
The Moon does orbit the Earth about once a month, but its orbit is tilted about 5 degrees to the Earth's orbit. Most months the Moon passes above or below the shadow of the Earth, so there is no eclipse.
