The correct answer is "insektisida." Insektisida is a type of pesticide specifically designed to eliminate insects such as mosquitoes and cockroaches. It is formulated to target and kill these pests, effectively controlling their population and preventing infestations. Other types of pesticides mentioned in the options, such as rodentisida (rodenticide), nematisida (nematicide), and fungisida (fungicide), are used for different purposes, such as controlling rodents, nematodes, and fungi, respectively.

The correct answer is "engsel" because the image shows a hinge, which is a type of joint that allows for rotation or movement between two objects. The other options, such as "putar" (rotate), "pelana" (saddle), and "peluru" (bullet), do not accurately describe the image.

The correct answer is alveolus. Alveolus is the part of the human respiratory system where the exchange of oxygen (O2) and carbon dioxide (CO2) takes place. It is a tiny air sac located at the end of the bronchioles in the lungs. Oxygen from inhaled air diffuses into the bloodstream through the thin walls of the alveoli, while carbon dioxide, a waste product, is expelled from the bloodstream into the alveoli to be exhaled. This exchange of gases is essential for respiration and providing oxygen to the body's cells.

The correct answer is "kerongkongan, lambung, usus halus" because in the given image, part number 1 is the esophagus (kerongkongan), part number 2 is the stomach (lambung), and part number 3 is the small intestine (usus halus).

The correct answer is "tulang rusuk dan tulang paha". The image shows two bones, one curved and one long, which correspond to the structure of the ribs and the thigh bone (femur) respectively. The other options do not match the shapes or sizes of the bones in the image.

The nose functions as a respiratory organ by regulating the humidity and temperature of the air that enters the lungs and by serving as the entry point for air from the outside. However, the actual exchange of oxygen and carbon dioxide takes place in the lungs, not in the nose.

The correct answer is "sebagai alat gerak aktif". This is because the other options, memberi bentuk tubuh, tempat melekatnya otot, and menegakkan badan, all describe functions of the skeletal system. The skeletal system provides support and structure to the body, serves as an attachment point for muscles, and helps in maintaining an upright posture. However, "sebagai alat gerak aktif" does not accurately describe a function of the skeletal system.

The correct answer is "hidung - tenggorokan - bronkus - bronkiolus - paru-paru" because it follows the correct sequence of the respiratory system. The air enters through the nose (hidung), then passes through the throat (tenggorokan), and continues down into the windpipe (bronkus). From there, it branches into smaller airways called bronchioles (bronkiolus), which lead to the lungs (paru-paru) where gas exchange occurs.

When the ribs are lifted and the diaphragm flattens, it creates more space in the chest cavity. This increase in volume allows the lungs to expand, causing air to be drawn into the lungs. This process is known as inspiration, and during inspiration, air enters the respiratory system. Therefore, the correct answer is "inspirasi, udara masuk."

The correct answer is 3 because bronchioles are small airways that branch off from the bronchi. In the given image, number 3 is pointing towards a structure that resembles bronchioles.

Sel darah merah adalah bagian dari darah yang berfungsi mengangkut oksigen (O2). Sel darah merah mengandung hemoglobin, protein yang dapat mengikat dan membawa oksigen ke seluruh tubuh. Hemoglobin berikatan dengan oksigen di paru-paru dan kemudian dilepaskan di jaringan tubuh yang membutuhkan oksigen. Dengan demikian, sel darah merah memainkan peran penting dalam proses respirasi dan pengangkutan oksigen ke seluruh tubuh.

Pencernaan mekanik dan kimiawi terjadi di mulut. Di mulut, makanan dipecah menjadi potongan-potongan kecil oleh gigi-gigi dan dicampur dengan air liur yang mengandung enzim amilase. Enzim amilase mulai mengubah karbohidrat menjadi gula sederhana. Pencernaan mekanik juga terjadi ketika lidah dan rahang membantu dalam mengunyah makanan. Proses ini mempersiapkan makanan untuk dicerna lebih lanjut di saluran pencernaan.

The correct answer is "jantung" because the image shown is a muscle that is specifically found in the heart. The other options mentioned, such as "lambung" (stomach), "usus" (intestine), and "tangan" (hand), are not relevant to the image provided. Therefore, the only logical choice is "jantung" (heart).

The given image shows an abnormal curvature of the spine that is exaggerated inward in the lower back region. This condition is known as lordosis. Lordosis is characterized by a noticeable arch in the lower back, causing the buttocks to protrude. It can be caused by various factors such as poor posture, obesity, pregnancy, or certain medical conditions.

Darah dengan golongan AB dapat diberikan pada seseorang yang bergolongan darah AB saja. Ini karena orang dengan golongan darah AB memiliki kedua antigen A dan B pada permukaan sel darah merah mereka, sehingga tidak akan mengalami reaksi imun saat menerima darah dengan antigen A atau B. Namun, orang dengan golongan darah A atau B hanya memiliki satu antigen (A atau B) pada sel darah merah mereka, sehingga mereka tidak cocok menerima darah dengan antigen yang berbeda. Orang dengan golongan darah O tidak memiliki antigen A atau B pada sel darah merah mereka, sehingga mereka hanya cocok menerima darah dengan golongan O saja.

Konstipasi adalah penyakit pada sistem pencernaan yang ditandai dengan susah buang air besar.

Nikotin pada rokok dapat menyebabkan ketagihan atau kecanduan pada penggunanya. Nikotin adalah zat adiktif yang dapat membuat seseorang terus merasa ingin merokok dan sulit berhenti. Kecanduan nikotin dapat menyebabkan ketergantungan fisik dan psikologis yang berdampak buruk pada kesehatan seseorang.

The question asks for the numbers that indicate synthetic flavorings. The correct answer is 5 and 7, which are "bawang merah" (red onion) and "penguat rasa monosodium glutamat" (monosodium glutamate flavor enhancer). These ingredients are commonly used as synthetic flavorings in instant noodles.

Based on the given image, it can be inferred that the vital capacity of the lungs is 5000 ml. This is determined by observing the highest point of the graph, which represents the maximum volume of air that can be exhaled after a maximum inhalation.

The correct answer is sel darah merah (eritrosit) because the image shows different components of blood, including white blood cells, red blood cells, plasma, and platelets. The red blood cells, also known as erythrocytes, are responsible for carrying oxygen to the body's tissues and removing carbon dioxide.

Pada gambar tersebut, terdapat nomor 3 yang menunjukkan proses pencernaan. Pencernaan yang terjadi di nomor 3 adalah protein menjadi pepton. Hal ini dapat diketahui dari pilihan jawaban yang menyebutkan bahwa protein menjadi pepton. Pepton adalah hasil dari pencernaan protein oleh enzim protease.

Manusia bernapas dengan bertujuan untuk menghasilkan energi. Melalui proses pernapasan, oksigen yang masuk ke dalam tubuh digunakan oleh sel-sel untuk mengoksidasi nutrisi dan menghasilkan energi yang diperlukan untuk berbagai aktivitas tubuh. Karbon dioksida yang dihasilkan dari proses ini kemudian dikeluarkan melalui pernapasan.

Penderita demam berdarah dapat mengalami pendarahan karena keping darah diserang oleh virus. Keping darah, juga dikenal sebagai trombosit, berperan penting dalam proses pembekuan darah. Ketika terjadi infeksi virus, virus tersebut dapat merusak keping darah dan mengganggu kemampuannya untuk membentuk gumpalan darah yang diperlukan untuk menghentikan pendarahan. Dengan demikian, penderita demam berdarah dapat mengalami pendarahan karena kekurangan atau kerusakan pada keping darah.

The correct answer is "serambi kanan, bilik kiri". This answer is based on the observation of the given image. It can be seen that number 1 is pointing towards the right side, indicating "serambi kanan" (right porch), while number 4 is pointing towards the left side, indicating "bilik kiri" (left room). Therefore, the correct answer is "serambi kanan, bilik kiri".

The correct answer is "blik kiri -- seluruh tubuh -- serambi kiri,bilik kiri --seluruh tubuh -- serambi kanan". This answer correctly identifies the sequence of blood flow in the systemic circulation. The blood is pumped out of the left ventricle (blik kiri) into the entire body (seluruh tubuh), supplying oxygen and nutrients to the tissues. It then returns to the heart through the right atrium (serambi kanan) before being pumped into the lungs for oxygenation in the pulmonary circulation.
