Batu apung
- B.
Batu granit
- C.
Batu kapur
- D.
Batu pualam

Segumpal tanah kebun dimasukkan ke dalam gelas berisi air, diaduk rata kemudian didiamkan beberapa saat ternyata berbentuk lapisan-lapisan terlihat pada gambar di bawah ini : yang merupakan tanah halus adalah
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The correct answer is B. This can be inferred from the information given in the question. It states that when a clump of garden soil is placed in a glass of water, stirred evenly, and left undisturbed for a while, layers can be seen. This suggests that the soil is composed of different sized particles, with the finer particles settling at the bottom and forming layers. Option B is the only one that represents fine soil particles.Rate this question:

Alat pernapasan manusia terdiri atas ........
- A.
Hidung - tenggorokan - jantung
- B.
Hidung - tenggorokan - hati
- C.
Hidung - tenggorokan - paru-paru
- D.
Hidung - kerongkongan - paru-paru
Correct Answer
C. Hidung - tenggorokan - paru-paruExplanation
The correct answer is "hidung - tenggorokan - paru-paru". The human respiratory system consists of the nose (hidung) which filters and warms the incoming air, the throat (tenggorokan) which serves as a passage for both air and food, and the lungs (paru-paru) which are responsible for the exchange of oxygen and carbon dioxide in the body. The heart (jantung) and liver (hati) are not part of the respiratory system.Rate this question:

- D.
Menggemukan tubuh
Correct Answer
D. Menggemukan tubuhExplanation
The statements given are all related to the functions or purposes of something in relation to the body. However, the statement "menggemukan tubuh" stands out as it does not align with the other statements. While the other statements discuss aspects such as shaping the body, providing attachment points for muscles, and supporting the body's upright position, "menggemukan tubuh" refers to the act of fattening or gaining weight, which is not directly related to the functions mentioned in the other statements.Rate this question:

Correct Answer
A. Bertambah banyakExplanation
The given answer, "bertambah banyak," is incorrect because it is actually one of the characteristics of growth in living organisms. Growth in living organisms can be observed through an increase in size, height, weight, and the overall expansion of the organism. Therefore, "bertambah banyak" should not be excluded as a characteristic of growth in living organisms.Rate this question:

Simbiosis mutualisme dapat terjadi antara ........
- A.
Lebah dan kelelawar
- B.
Lebah dan mangga
- C.
Kelelawar dan mangga
- D.
Kenyamanan dan kepuasan tidur
Correct Answer
B. Lebah dan manggaExplanation
Symbiosis mutualism is a type of relationship where both organisms involved benefit from each other. In this case, the correct answer is "lebah dan mangga" which means bees and mangoes. Bees are attracted to the nectar in mango flowers and while they collect nectar, they also transfer pollen from one flower to another, which helps in the fertilization process of the mango trees. This benefits the bees by providing them with food, and it benefits the mango trees by ensuring successful reproduction.Rate this question:

C. Kayu, rotan, damar, dan karetExplanation
The correct answer is "kayu, rotan, damar, dan karet". These resources are considered renewable because they can be replenished or replaced naturally over time. Wood, rattan, dammar, and rubber are all derived from plants that can be grown and harvested sustainably. This means that as long as proper management practices are in place, these resources can continue to be used without depleting their supply.Rate this question:

Gerakan kelereng yang menggelinding di lantai datar, makin lama makin lambat dan akhirnya berhenti. Hal ini terjadi akibat bekerjanya gaya ........
- A.
Otot
- B.
Gravitasi
- C.
Pegas
- D.
Gesek
Correct Answer
D. GesekExplanation
The correct answer is "gesek." When a marble rolls on a flat surface, it experiences frictional force or gesek. This force opposes the motion of the marble and causes it to slow down over time. Eventually, the frictional force becomes strong enough to bring the marble to a complete stop. Therefore, gesek is the force responsible for the marble's decreasing speed and eventual stoppage.Rate this question:

- B.
Gerak
- C.
Bunyi
- D.
Pegas
Correct Answer
B. GerakExplanation
When an object undergoes a change in shape, it requires energy to deform and then return to its original shape. This energy is in the form of kinetic energy, which is associated with the movement of the object. Therefore, the correct answer is "gerak" (motion).Rate this question:

Perambatan panas cahaya matahari sampai di bumi berlangsung secara .....
- A.
Konduksi
- B.
Konveksi
- C.
Radiasi
- D.
Refleksi
Correct Answer
C. RadiasiExplanation
Radiasi adalah proses perambatan panas atau energi dalam bentuk gelombang elektromagnetik, seperti sinar matahari yang mencapai bumi. Pada perambatan panas cahaya matahari, tidak terjadi perpindahan partikel atau medium seperti pada konduksi dan konveksi. Refleksi adalah pemantulan cahaya oleh suatu permukaan, bukan perambatan panas. Oleh karena itu, radiasi adalah jawaban yang tepat.Rate this question:

Salah satu keuntungan menanam pohon mangga dengan cara cangkok adalah ........
- A.
Tidak memerlukan tanah yang subur
- B.
Tahan terhadap hama tanaman
- C.
Tidak memerlukan pemeliharaan
- D.
Sifat tanaman sama dengan induknya
Correct Answer
D. Sifat tanaman sama dengan induknyaExplanation
When mango trees are propagated through grafting, the scion (the upper part of the plant) is taken from a mature mango tree with desirable traits and attached to a rootstock (the lower part of the plant) of a different variety. This allows the grafted tree to inherit the same characteristics as the parent tree, such as fruit quality, taste, and size. Therefore, the advantage of grafting mango trees is that the resulting plant will have the same traits as the parent tree.Rate this question:

Tumbuhan berumah dua artinya bunga jantan dan bunga betina terpisah pada pohon lain, misalnya ........
- A.
Pepaya
- B.
Mangga
- C.
Salak
- D.
Rambutan
Correct Answer
C. SalakExplanation
The correct answer is salak because salak is a plant that has separate male and female flowers on different trees. This means that the male flowers are found on one tree and the female flowers are found on another tree. This characteristic of having separate male and female flowers on different trees is what makes salak a dioecious plant, or a plant with separate sexes.Rate this question:

- C.
Tomat, terung, dan cabai
- D.
Pohon jati, mahoni, dan lengkeng
Correct Answer
B. Putri malu, turi, dan lamtoroExplanation
Putri malu, turi, dan lamtoro are the correct answer because these plants have leaves that are sensitive to darkness or touch. When these plants are exposed to darkness or touched, their leaves will fold or close up as a response to the stimulus. This is a defense mechanism to protect the plants from potential harm or damage.Rate this question:

- B.
Permukaan B turun dan A naik
- C.
Permukaan A dan B turun
- D.
Permukaan A dan B naik
Correct Answer
A. Permukaan A turun dan B naikExplanation
When the elemeyer vessel is heated, the water in the U-shaped pipe will experience thermal expansion. As a result, the water level in side A of the U-shaped pipe will decrease because the heated water expands and moves towards side B, causing the water level in side B to rise. Therefore, the correct answer is "Permukaan A turun dan B naik" which means "The surface of A goes down and B goes up."Rate this question:
