    • 7.5 kg

    • 3,5 kg

    • 3,3 kg

    • 0,3 kg

    Correct Answer
    A. 7.5 kg
    Explanation
    The given question asks for the mass of an object given its density and volume. The density is given as 1.5 kg/m3 and the volume is given as 5 m3. To find the mass, we can use the formula mass = density * volume. Plugging in the given values, we get mass = 1.5 kg/m3 * 5 m3 = 7.5 kg. Therefore, the correct answer is 7.5 kg.

    Correct Answer
    A. Ditemukannya vaksin untuk meningkatkan daya tahan tubuh terhadap penyakit tertentu
    Explanation
    The correct answer is "ditemukannya vaksin untuk meningkatkan daya tahan tubuh terhadap penyakit tertentu" because it states that the benefit of biotechnology in the field of health is the discovery of vaccines to enhance the body's immune system against specific diseases. This aligns with the potential of biotechnology to develop and produce vaccines using advanced techniques and genetic engineering to prevent and control diseases.

    Correct Answer
    A.
    Explanation
    The correct answer is "6CO2 + 6H2O -> C6H12O6 + 6O2". This equation represents the balanced chemical reaction for photosynthesis, where carbon dioxide (CO2) and water (H2O) react in the presence of sunlight and chlorophyll to produce glucose (C6H12O6) and oxygen (O2). This process is essential for plants to convert sunlight energy into chemical energy for growth and survival.

    • 1,2,4

    • 2,3,5

    • 2,4,5

    Correct Answer
    A. 2,3,5
    Explanation
    The correct answer is 2,3,5 because these factors can accelerate the process of evaporation. Factor 2, reducing the pressure on the liquid, can lower the boiling point and speed up evaporation. Factor 3, expanding the surface area of the liquid, provides more surface for evaporation to occur. Factor 5, flowing air above the liquid, can carry away the water vapor and create a concentration gradient that enhances evaporation. Therefore, these factors combined can contribute to a faster evaporation process.

    Correct Answer
    A. Mengidap polio dan posisi duduk yang salah
    Explanation
    The correct answer is "mengidap polio dan posisi duduk yang salah". The image shows a person with a physical disability in their legs, which is characteristic of polio. Additionally, the person's sitting position is incorrect, which can further exacerbate their condition.

    • Nutrisi dan kelembaban

    • Suhu dan Genetik

    Correct Answer
    A. Nutrisi dan kelembaban
    Explanation
    Nutrisi dan kelembaban adalah faktor eksternal yang mempengaruhi proses pertumbuhan dan perkembangan pada tumbuhan. Nutrisi yang cukup dan seimbang diperlukan oleh tumbuhan untuk melakukan fotosintesis dan sintesis zat-zat penting lainnya. Kelembaban yang tepat juga penting untuk menjaga keseimbangan air dalam tumbuhan dan mempengaruhi proses transpirasi. Keduanya saling berinteraksi dan berperan dalam memberikan kondisi optimal bagi pertumbuhan dan perkembangan tumbuhan.

    • 0,12 kg

    • 0,30 kg

    • 120,00 kg

    • 300,00 kg

    Correct Answer
    A. 0,12 kg
    Explanation
    The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of a unit mass of that substance by one degree Celsius. In this question, the water is heated with 6000 J of heat energy and its temperature increases by 50 degrees Celsius. Since the specific heat capacity of water is 1000 J/kg.°C, we can use the formula:

    Heat energy = mass × specific heat capacity × change in temperature

    6000 J = mass × 1000 J/kg.°C × 50 °C

    Solving for mass, we get:

    mass = 6000 J / (1000 J/kg.°C × 50 °C) = 0.12 kg

    Therefore, the mass of the water that was heated is 0.12 kg.

    • Filtrat tubulus

    • Filtrat glomerulus

    • Urine sekunder

    • Urine sesungguhnya

    Correct Answer
    A. Urine sesungguhnya
    Explanation
    The correct answer is "urine sesungguhnya." This is because the process of urine formation in the nephron of the kidney involves several steps, including filtration, reabsorption, and secretion. After the filtrate passes through the tubules and undergoes reabsorption and secretion, it is then transformed into urine. Therefore, "urine sesungguhnya" refers to the final product of this process.

    • 12

    • 16

    Correct Answer
    A. 8
    Explanation
    When a red and white four o'clock flower is crossed, it produces a pink flower F1. If the F1 is crossed with itself and produces 32 plants in F2, there is a possibility of producing 8 plants with red flowers. This is because the F1 generation is a result of a cross between two different flower colors, so it is heterozygous for flower color. When the F1 generation is self-crossed, it can produce offspring with different combinations of alleles for flower color, including the possibility of producing plants with red flowers.

    Explanation
    The correct answer is 1, 2, and 4. This is because the statement mentions that the epidermis is found on the surface of the plant body, it functions to protect the underlying tissues, and it is composed of a single layer of the same type of cells. Statement 3 is incorrect because it mentions that the epidermis contains chloroplasts with a small amount, which is not true. Statement 5 is also incorrect because it mentions that the epidermis stores food reserves, which is not one of its characteristics.

    Correct Answer
    A. 1 dan 3
    Explanation
    The correct answer is 1 and 3 because both statements describe examples of plant movements in response to stimuli. Statement 1 refers to the splitting of mature seed pods in dry air, which is a response to environmental conditions. Statement 3 refers to the growth of a seedling towards a light source, which is a response to a specific stimulus. Therefore, both statements demonstrate plant movements caused by external factors or stimuli.

    Perjalanan impuls pada gerak reflex saat kita bersin adalah ….

    Correct Answer
    A.
    Explanation
    Perjalanan impuls pada gerak reflex saat kita bersin adalah sangat cepat dan tidak melibatkan otak. Ketika kita bersin, impuls sensorik dari hidung menuju sumsum tulang belakang, kemudian impuls motorik langsung dikirimkan kembali ke otot-otot yang terlibat dalam proses bersin. Ini adalah respons refleks yang melibatkan saraf-saraf tepi dan sumsum tulang belakang tanpa melibatkan otak untuk menghemat waktu dan energi.

    • 3, 4 dan 1

    Correct Answer
    A. 3, 4 dan 1
    Explanation
    The correct answer is 3, 4, and 1. This is because during the expiratory phase of abdominal breathing, the diaphragm muscles relax and move upward, causing the volume of the lung cavity to decrease. As a result, the pressure in the lungs increases, and air is forced out of the lungs. This process involves the contraction of the diaphragm muscles, the movement of air out of the lungs, and the decrease in the size of the lung cavity.
