Pasangan gambar yang merupakan molekul unsur adalah …
Correct Answer
A. (1) dan (3)
Explanation
The correct answer is (1) and (3) because in both images, there are individual atoms that are not bonded to any other atoms. This indicates that they are separate molecules of an element. In images (2) and (4), there are multiple atoms bonded together, suggesting that they are molecules of compounds rather than individual elements.

Sebuah lup berfokus 5 cm digunakan untuk mengamati benda yang panjangnya 4 mm. Panjang bayangan benda apabila mata tidak berakomodasi adalah …
Correct Answer
A. 2,0 cm
Explanation
The given question is about using a 5 cm focal length lens to observe an object that is 4 mm long. The question asks for the length of the shadow when the eye does not accommodate. The length of the shadow can be calculated using the formula: Shadow length = (Object length x Focal length) / Object distance. Since the object distance is not given, we can assume it to be infinity when the eye does not accommodate. Therefore, the shadow length would be 2.0 cm.

Correct Answer
A. Ekosistem
Explanation
The correct answer is "Ekosistem." An ecosystem is a community of living organisms (producers, consumers, and decomposers) interacting with their non-living environment (abiotic factors). It involves a complex network of relationships and interactions between living and non-living components. This answer aligns with the given information that the relationship between living and non-living components includes producers, consumers, and decomposers (living) and non-living objects.

Bandul berayun dari A ke B dalam waktu 0,4 sekon. Frekuensi dan amplitudo ayunan bandul adalah …
Correct Answer
C. 0,625 Hz dan 4 cm
Explanation
The correct answer is 0,625 Hz dan 4 cm. This is because the frequency of a pendulum is calculated by dividing 1 by the time period, which in this case is 0.4 seconds. So, 1/0.4 = 2.5 Hz. However, the question asks for the frequency in Hz, so we need to round it to the nearest decimal place, which is 0.625 Hz. The amplitude of the pendulum swing is given as 4 cm.

- Benda yang terbentuk maya, tegak, diperkecil
- Bayangan yang terbentuk nyata, terbalik, diperkecil
- Diafragma berfungsi mengatur besar kecilnya intensitas cahaya yang masuk
Pernyataan di atas yang benar tentang kamera adalah nomor …
Correct Answer
C. 1), 4), dan 5)
Explanation
The correct answer is 1), 4), and 5). The statement "Menggunakan lensa cekung" (Using a concave lens) is incorrect because cameras typically use convex lenses. The statement "Benda yang terbentuk maya, tegak, diperkecil" (The object formed is virtual, upright, and reduced in size) is correct as the image formed by a camera is virtual, upright, and smaller than the actual object. The statement "Bayangan yang terbentuk nyata, terbalik, diperkecil" (The image formed is real, inverted, and reduced in size) is also correct as the image formed by a camera is real, inverted, and smaller in size. The statement "Diafragma berfungsi mengatur besar kecilnya intensitas cahaya yang masuk" (The diaphragm functions to control the intensity of the incoming light) is correct as the diaphragm in a camera controls the amount of light entering the lens.

Correct Answer
B. Rongga dada membesar, paru-paru mengembang, volume paru-paru membesar dan tekanan udara di dalam paru-paru mengecil
Explanation
When the diaphragm is in the position described, the chest cavity expands, causing the lungs to inflate. As the lungs expand, the volume of the lungs increases, creating a decrease in air pressure inside the lungs. This decrease in pressure allows air to enter the lungs, facilitating the process of inhalation.

Palisade
Fotosintesis
Explanation
The correct answer is "Palisade" and "Fotosintesis" because the palisade tissue is responsible for photosynthesis in plants. It contains chloroplasts, which are the sites of photosynthesis, and is located in the upper part of the leaf where it can receive the most sunlight. Therefore, the palisade tissue plays a crucial role in the process of photosynthesis, which is the conversion of light energy into chemical energy in plants.

Correct Answer
A. Membutuhkan sinar matahari dan menghasilkan amilum
Explanation
The given correct answer states that photosynthesis requires sunlight and produces starch. This is because photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose (a type of sugar) and oxygen. Glucose is then converted into starch for storage in plants. Therefore, the answer accurately describes the key components and products of photosynthesis.

The correct answer is (1), (4), (2), (3). This is because the balok with the highest pressure would be the one at the bottom, which is (1). The balok on top of it, (4), would have a slightly lower pressure. The balok on the side, (2), would have a lower pressure compared to (4), and the balok on the top, (3), would have the lowest pressure among all the balok.

Correct Answer
D. Kerusakan pada cortex ginjal sehingga urin mengandung albumin
Explanation
The correct answer is "Kerusakan pada cortex ginjal sehingga urin mengandung albumin." This is because the passage states that Pak Oji suffers from kidney stones, which can cause damage to the cortex of the kidneys. This damage can lead to the presence of albumin in the urine, a condition known as albuminuria. The other options mentioned, such as inflammation in the kidneys, impaired bilirubin flow, or obstructed bile fluid flow, are not directly related to the symptoms described in the passage.

Ayah membawa dua karung rambutan menggunakan sepeda motor. Jika berat badan ayah 64 kg dan berat kedua karung rambutan 160 hg dan 0,25 kuintal , berat seluruh beban pada sepeda motor….kg
Correct Answer
D. 1.050
Explanation
The weight of the father is given as 64 kg. The weight of the two sacks of rambutan is given as 160 hg and 0.25 kuintal. To find the total weight, we need to convert the weight of the sacks to kg. 1 hg is equal to 0.1 kg, so 160 hg is equal to 16 kg. 1 kuintal is equal to 100 kg, so 0.25 kuintal is equal to 25 kg. Adding the weight of the father and the weight of the sacks, we get a total weight of 105 kg. Therefore, the correct answer is 1.050 kg.

Kelipatan persekutuan terkecil ( KPK ) dari 36 dan 96 dalam bentuk faktorisasi adalah …
Correct Answer
D. 25 x 32
Explanation
The smallest common multiple (KPK) of 36 and 96 can be found by factoring both numbers. The prime factorization of 36 is 2^2 x 3^2, and the prime factorization of 96 is 2^5 x 3. To find the KPK, we need to take the highest power of each prime factor. In this case, the highest power of 2 is 2^5 and the highest power of 3 is 3^2. Therefore, the KPK of 36 and 96 is 2^5 x 3^2, which is equal to 25 x 32.

Ibu mempunyai persediaan minyak goreng 5/6 liter. Ibu menggunakan minyak goreng 0,75 liter untuk menggoreng ikan . Ibu membeli lagi minyak goreng 2 1/4 liter. Persediaan minyak goreng sekarang masih … liter
Correct Answer
D. 2\frac{1}{3}
Explanation
The mother initially had 5/6 liter of cooking oil. She used 0.75 liters to fry fish, leaving her with 5/6 - 0.75 = 2/3 liters of cooking oil. She then bought an additional 2 1/4 liters of cooking oil. To add these fractions, we need to find a common denominator, which is 12. So, 2 1/4 can be written as 9/4. Adding 2/3 and 9/4 gives us (8/12 + 27/12) = 35/12, which can be simplified to 2 11/12. Therefore, the mother now has 2 11/12 liters of cooking oil. However, this is not one of the answer choices. The closest option is 2 1/3, which is approximately equal to 2 4/12. Hence, the correct answer is 2 1/3.
