The interaction between bees collecting nectar from flowers, while the presence of bees helps in the process of flower pollination, is classified as mutualism. In mutualism, both species involved in the interaction benefit from each other's presence and actions. In this case, the bees benefit by obtaining food (nectar) from the flowers, while the flowers benefit from the bees' help in pollination, which allows them to reproduce.

The correct answer suggests that one way to reduce air pollution caused by factory emissions is to create a proper installation for the disposal of smoke or gas. This means that the installation should be designed in a way that effectively captures and removes harmful emissions, preventing them from being released into the surrounding environment. By implementing a well-designed disposal system, the factory can minimize the impact of its emissions on air quality.

The correct answer is tartrazin Cl 19140. This is a synthetic food coloring that is commonly used in food packaging. It is often added to give a yellow or orange color to the food product.

The given image shows a plant with roots in the soil. This indicates that living organisms, like plants, require nutrients from the soil for their growth and development. Nutrients such as minerals and water are essential for the plant's survival and to carry out various metabolic processes. Therefore, the correct answer is "memerlukan nutrisi" (require nutrients).

Based on the given information, the solution has a bitter taste, can conduct electricity, and turns red litmus blue. These are characteristic properties of a base. Therefore, the solution can be predicted to be a base.

The correct answer is 3 dan 4. This is because animals in groups 3 and 4 are depicted with lungs, which are organs used for respiration. Animals in groups 1 and 2 are shown with gills, which are used for respiration in water. Therefore, the correct answer is 3 dan 4, as these groups represent animals that breathe using lungs.

The correct answer is "Karbon, oksigen, hidrogen." This is because carbon, oxygen, and hydrogen are elements that are commonly found in various substances in our daily lives. Salt and sugar are compounds that contain these elements, but they are not elements themselves. Water is a compound made up of hydrogen and oxygen, but it does not contain carbon. Therefore, the correct answer is the option that lists the elements carbon, oxygen, and hydrogen.

Grafik tersebut menunjukkan hubungan yang positif antara kepadatan populasi manusia (X) dan kebutuhan makanan (Y) di suatu daerah. Hal ini dapat dilihat dari garis yang naik dari kiri bawah ke kanan atas, menunjukkan bahwa semakin tinggi kepadatan populasi manusia, semakin tinggi pula kebutuhan makanan. Ini menunjukkan bahwa semakin banyak populasi manusia, semakin besar pula kebutuhan makanan yang harus dipenuhi.

The correct answer is 2 and 3. Based on the given information, the enzyme that converts protein into peptone and amino acids is produced by organs indicated by numbers 2 and 3.

The given substances, such as Putaw, heroin, alcohol, diazepam, and morfin, are examples of psychotropic substances that have a depressant effect. This means that they slow down the central nervous system, resulting in sedation and decreased mental and physical activity. One of the visible symptoms of using these substances is losing consciousness or being unconscious.

When a ferromagnetic material such as iron is repeatedly rubbed, it can become magnetized. In this case, the iron bar AB becomes magnetized with the north pole (N) at point B. This is indicated by the correct answer B, which states that the iron bar AB becomes a north pole magnet.

The correct answer is "perubahan kelompok bintang yang tampak dari bumi". This is because the rotation of the Earth causes the apparent movement of stars in the night sky. As the Earth rotates on its axis, different constellations become visible at different times of the year. This phenomenon is known as the apparent motion of stars and is a result of the Earth's rotation.

The correct answer states that rusting can only occur on iron metals. This is because rusting is a specific type of corrosion that only affects iron and its alloys. Other metals may undergo different types of corrosion, but rusting specifically refers to the formation of iron oxide on iron surfaces.

The correct answer is 2,3,4. This is because the factors that affect the induced electromotive force (EMF) at the ends of the wire are the number of turns of the coil (jumlah lilitan), the cross-sectional area of the wire (penampang kawat), and the motion of the magnet (gerak magnet) as well as the magnetic field strength (gaya magnet). These factors determine the strength of the magnetic field and the rate at which the magnetic field lines cut through the wire, thus inducing an EMF.
