Tumbuhan adalah mahluk hidup yang mampu menggunakan sinar matahari untuk mengolah makanan melalui proses fotosintesis. Proses ini melibatkan penggunaan energi matahari untuk mengubah air dan karbon dioksida menjadi glukosa dan oksigen. Tumbuhan memiliki pigmen klorofil yang memungkinkan mereka menyerap energi matahari dan menggunakannya untuk pertumbuhan dan perkembangan. Oleh karena itu, tumbuhan adalah satu-satunya kelompok mahluk hidup yang dapat melakukan fotosintesis dan memanfaatkan sinar matahari sebagai sumber energi utama.

The given options represent different types of symbiosis, which is a close and long-term interaction between two different species. Mutualism is a type of symbiosis where both species benefit from the interaction. Parasitism is a type of symbiosis where one species benefits at the expense of the other. Commensalism is a type of symbiosis where one species benefits while the other is unaffected. However, "netral" is not a recognized type of symbiosis, hence it is the exception in the given options.

The correct answer states that the impact of population density on environmental damage is that it tends to increase. This means that as the population density increases, there is a higher likelihood of environmental damage occurring. This could be due to increased resource consumption, pollution, deforestation, or other factors associated with a higher population density. Therefore, the correct answer suggests that population density has a negative impact on the environment, leading to an increase in environmental damage.

Buaya, kupu-kupu, ular, udang, katak, dan hiu bukan termasuk dalam kelas Mamalia karena mereka memiliki karakteristik yang berbeda seperti tidak memiliki kelenjar susu, tidak memiliki rambut atau bulu, dan memiliki sistem reproduksi yang berbeda.

The correct answer is "kedudukan benda itu berubah terhadap titik acuan". This answer states that an object is considered to be moving if its position changes with respect to a reference point. This explanation aligns with the concept of motion, where an object's position is constantly changing in relation to a fixed point of reference.

The correct answer is "urea dalam keringat" because sweat is primarily composed of water, salt, and urea. Urea is a waste product that is produced in the liver when proteins are broken down. It is then excreted through sweat glands in the form of sweat. Urea helps regulate the body's water balance and plays a role in removing waste from the body.

Sanitasi yang sehat tidak akan meningkatkan angka kematian suatu negara, karena sanitasi yang sehat sebenarnya akan membantu mencegah penyebaran penyakit dan menjaga kesehatan masyarakat. Faktor-faktor lain seperti bencana alam, peperangan, dan buruknya kesehatan dapat menyebabkan kondisi yang tidak aman dan berdampak negatif pada kesehatan masyarakat, sehingga dapat meningkatkan angka kematian.

The correct answer is "meja preparat" because it refers to the platform or stage where the specimen or slide is placed for observation under the microscope. This is where the slide is secured and positioned for viewing and analysis. The other options, such as "gelas benda" (glass slide), "lensa obyektif" (objective lens), and "kaca penutup" (cover glass), are not the correct answers as they do not specifically refer to the platform where the slide is placed.

Tumbuhan laut berperan sebagai produsen pada ekosistem air laut karena mereka mampu melakukan fotosintesis dan menghasilkan makanan sendiri menggunakan energi matahari. Mereka juga merupakan sumber makanan utama bagi hewan-hewan herbivora di laut, seperti ikan kecil. Hiu dan paus, meskipun merupakan bagian dari ekosistem air laut, bukanlah produsen karena mereka bergantung pada makanan yang diperoleh dari organisme lain dalam rantai makanan.

The term "pertumbuhan penduduk" refers to the increase in the population over a specific period of time. It signifies the change in the number of individuals in a population, indicating that the population has grown or expanded. This can occur due to various factors such as birth rates exceeding death rates, immigration, or a decrease in emigration. Therefore, the correct answer is "perubahan penduduk jadi lebih banyak" which means the change in the population becomes more numerous.

The correct answer is "seekor monyet" because the question is asking for an example of an individual, and out of the given options, a monkey is the only one that represents a single individual. The other options refer to a group of ducks, a cage of chickens, and a piece of chicken leg, which do not fit the criteria of being an individual.

Asam klorida adalah contoh bahan kimia yang bersifat korosif karena memiliki sifat yang dapat merusak atau menghancurkan bahan-bahan organik maupun anorganik. Asam klorida memiliki sifat asam yang kuat dan bersifat korosif terhadap logam, kulit, dan jaringan tubuh manusia. Ketika terkena kulit atau mata, asam klorida dapat menyebabkan luka bakar dan iritasi yang parah. Oleh karena itu, asam klorida dianggap sebagai bahan kimia yang bersifat korosif.

The average speed of a motorcycle is calculated by dividing the distance traveled by the time taken. In this case, the motorcycle traveled a distance of 20 km in a time of 15 minutes. To convert the time to hours, we divide by 60 (15 minutes = 15/60 = 0.25 hours). Therefore, the average speed is 20 km / 0.25 hours = 80 km/h.

A temporary answer or explanation for the problem being researched, which is then tested for its validity, is called a hypothesis. A hypothesis is a proposed explanation or prediction based on limited evidence or prior knowledge. It serves as a starting point for further investigation and experimentation to determine its accuracy.

After conducting an experiment, to further strengthen the hypothesis, it is necessary to perform a repeat experiment. This helps to validate the initial findings and ensure that the results are consistent and reliable. By conducting the experiment again, any potential errors or inconsistencies can be identified and corrected, increasing the credibility of the hypothesis.

Pak Rusli berangkat dari kota A pukul 08.00 dan menggunakan motor dengan kecepatan rata-rata 40 km/jam. Jarak antara kota A dan kota B adalah 120 km. Untuk mencari waktu tiba di kota B, kita dapat menggunakan rumus waktu = jarak/kecepatan. Dalam hal ini, waktu = 120 km / 40 km/jam = 3 jam. Jadi, jika Pak Rusli berangkat pukul 08.00, ia akan tiba di kota B pada pukul 11.00.

Gerak lurus berubah beraturan dipercepat adalah gerak yang kecepatannya bertambah secara terus-menerus seiring dengan waktu. Dalam contoh gerak di atas, gerak yang termasuk gerak lurus berubah beraturan dipercepat adalah bola menuruni bidang miring (nomor 3) karena kecepatannya akan terus bertambah seiring dengan turunnya bola di bidang miring tersebut. Sedangkan gerak bola jatuh bebas (nomor 1) tidak termasuk gerak lurus berubah beraturan dipercepat karena kecepatannya tetap konstan saat bola jatuh.

The correct answer is "kecepatan benda berubah secara teratur". GLBB stands for Gerak Lurus Berubah Beraturan, which translates to Uniformly Changing Straight Motion. This means that the speed of the object is changing in a regular and consistent manner. It is not staying constant, increasing, or changing randomly.

The correct order of steps in the scientific method is 5-1-4-2-3-6. The first step is identifying the problem or question (5), followed by collecting data (1). Then, a hypothesis is formed (4) based on the data collected. Next, experiments (2) are conducted to test the hypothesis. The results of the experiments lead to drawing conclusions (3). Finally, the process is repeated (6) to confirm the findings and ensure the validity of the results.

The correct answer is sel-jaringan-organ-sistem organ-organisma. This is the correct order of the hierarchical organization of living organisms, starting from the lowest level to the highest level. It begins with cells, which are the basic building blocks of life. Cells then combine to form tissues, which in turn form organs. Organs work together to form organ systems, and finally, all the organ systems together make up an organism.

The correct answer is 30 m/s. To convert km/h to m/s, we need to divide the value by 3.6. Therefore, 108 km/h divided by 3.6 equals 30 m/s.

The correct answer is "berfotosintesis dan mendengar". This is because photosynthesis is a characteristic of plants, not living organisms in general. Additionally, hearing is a characteristic of animals, not all living organisms. The other options, "mendengar dan beradaptasi", "melihat dan membutuhkan oksigen", and "mengeluarkan zat sisa dan bernafas", are all characteristics that can be attributed to living organisms in general.

During her movement, Siska walks straight from point A to point B for a distance of 100 meters. Then, she changes direction and walks straight from point B to point C for a distance of 20 meters. The total distance covered by Siska is the sum of these two distances, which is 120 meters. On the other hand, her displacement is the straight-line distance between her initial and final positions, which is 80 meters.

Penanaman monokultur adalah usaha manusia yang dapat menurunkan keanekaragaman hayati. Monokultur adalah praktik menanam satu jenis tanaman secara intensif di suatu area yang luas, menggantikan keanekaragaman alami dengan satu jenis tanaman yang dominan. Hal ini dapat mengurangi keberagaman hayati karena menghilangkan habitat dan sumber makanan bagi spesies lain. Selain itu, monokultur juga meningkatkan risiko terjadinya penyakit dan hama yang dapat menyebar dengan cepat di antara tanaman yang sama.

The correct answer is "menangkap bayangan dari lensa obyektif." The function of an eyepiece lens is to capture the image formed by the objective lens and magnify it for the viewer. It does not focus or clarify the object, but rather receives the image formed by the objective lens and presents it to the viewer.

The correct answer is "membuat pingsan hewan." Chloroform or ether is used in surgery to induce anesthesia and make animals unconscious. This allows the surgical procedures to be performed without causing pain or distress to the animal.

The given passage states that the ozone layer is thinning due to the high levels of CFC in the air. CFC is found in various objects, except for liquid waste from factories. This suggests that liquid waste from factories does not contain CFC, unlike the other options such as spray cosmetics, car refrigerants, and spray paint for cars.

The correct answer is natalitas. Natalitas refers to the birth rate or the number of births in a population. It is the term used to describe the phenomenon of the birth of new individuals. The other options, mortalitas, emigrasi, and imigrasi, do not relate to the birth of new individuals but rather refer to mortality (death rate), emigration (leaving one's country), and immigration (entering a new country) respectively.

The correct answer is "mikrometer". Mikrometer is a part of a microscope that is used to adjust the focus of the image by slowly raising or lowering the microscope tube. It is responsible for fine-tuning the focus and ensuring clear and sharp images. The other options mentioned - revolver, diafragma, and lensa obyektif - are not directly related to adjusting the focus of the microscope.

The correct answer is "jarak yang ditempuh selalu tetap dalam selang waktu yang berbeda". This means that the object always covers the same distance in different time intervals. This suggests that the object is moving at a constant speed, as it covers equal distances in equal amounts of time.

Plastida adalah organel sel tumbuhan yang tidak dimiliki oleh sel hewan. Plastida terdiri dari beberapa jenis, seperti kloroplas yang berperan dalam fotosintesis, dan lekoplast yang berperan dalam penyimpanan zat-zat makanan. Sel hewan tidak memiliki plastida, sehingga menjadikan plastida sebagai jawaban yang benar.

The combination of a group of horses, a group of lions, and a group of deer in a grassland forms a community. A community refers to a group of different populations of organisms living and interacting with each other in a specific area. In this case, the horses, lions, and deer are different populations of organisms that coexist and interact within the grassland ecosystem. Therefore, the correct answer is "komunitas" which translates to "community" in English.

Plants that are grouped based on their usefulness can be categorized as "hiasan" or ornamental plants. These plants are primarily grown for decorative purposes, such as beautifying gardens, indoor spaces, or events. They are not typically cultivated for their economic or practical value, but rather for their aesthetic appeal.

The greenhouse effect is caused by high levels of greenhouse gases in the atmosphere. One of the main greenhouse gases is carbon dioxide. When these gases are released into the atmosphere, they trap heat from the sun, leading to an increase in global temperatures. Carbon monoxide, sulfur dioxide, and nitrite are also pollutants, but they do not have the same impact on the greenhouse effect as carbon dioxide.

Emigrasi adalah perpindahan penduduk dari dalam negeri ke luar negeri. Dalam konteks ini, penduduk memilih untuk meninggalkan negara asalnya dan pindah ke negara lain untuk mencari pekerjaan, pendidikan, atau alasan lainnya. Ini berbeda dengan imigrasi, yang merujuk pada perpindahan penduduk dari luar negeri ke dalam negeri. Transmigrasi adalah program pemerintah yang mengalihkan penduduk dari satu daerah ke daerah lain di dalam negeri. Urbanisasi adalah perpindahan penduduk dari pedesaan ke perkotaan.

The correct answer is "jaringan darah dan rangka" because blood and skeletal tissues are both examples of connective tissues found in animals. Blood tissue connects various parts of the body through the circulatory system, while skeletal tissue provides support and structure to the body.

War affects mortality rates. War leads to an increase in deaths due to direct violence, injuries, and diseases caused by the destruction of infrastructure and healthcare systems. It also leads to displacement and migration, which can further increase mortality rates due to lack of access to basic necessities and healthcare. Therefore, the correct answer is mortalitas.

Taman Nasional Ujung Kulon di Jawa Barat melindungi hewan babi hutan.

Serangga dapat berperan sebagai produsen air tawar karena beberapa spesies serangga seperti capung dan nyamuk betina menggunakan air tawar sebagai tempat berkembang biak. Mereka bertelur dan menempelkannya di permukaan air tawar, sehingga menjadi produsen air tawar yang penting bagi ekosistem air.
