The frequency of respiration is influenced by several factors such as gender, body temperature, body weight, body position, and physical activity. However, body weight is not one of the factors that affect the frequency of respiration.

The correct answer is vitamin, mineral. The question is asking for the components of a micro food substance. Vitamins and minerals are essential nutrients that our body needs in small amounts for proper functioning. They play important roles in various bodily functions such as metabolism, immune system support, and maintaining healthy bones and tissues. Protein, carbohydrates, and fats are macronutrients and not considered micro food substances.

The correct answer is "trakea". The respiratory system in insects is called trachea. Trachea is a network of tubes that deliver oxygen directly to the cells of the insect's body. This system allows for efficient gas exchange without the need for lungs or gills.

Udara yang dapat keluar dari paru-paru sekitar 1.500 mL disebut udara suplementer. Ini adalah udara tambahan yang dapat dihembuskan setelah ekshalasi normal. Udara suplementer membantu meningkatkan ventilasi paru-paru dan memungkinkan lebih banyak udara masuk dan keluar dari paru-paru.

Karbohidrat adalah zat makanan yang paling cepat dipakai dalam pembakaran. Karbohidrat merupakan sumber utama energi bagi tubuh manusia. Setelah dikonsumsi, karbohidrat diubah menjadi glukosa yang kemudian digunakan oleh sel-sel tubuh sebagai bahan bakar untuk melakukan berbagai aktivitas. Proses ini lebih cepat dibandingkan dengan pemecahan protein atau lemak menjadi energi. Vitamin dan mineral, meskipun penting bagi kesehatan tubuh, tidak berperan langsung dalam pembakaran energi.

The smallest structural and functional unit in the kidney is called a nephron. It is responsible for filtering the blood and producing urine. The nephron consists of several components, including the glomerulus, Bowman's capsule, and the renal tubules. These structures work together to filter waste products and excess fluids from the blood, reabsorb necessary substances, and regulate the concentration of electrolytes in the body. Therefore, the correct answer is nephron.

The correct answer is 1, 3, 4, and 5. This is because the organs listed in the options are the ones that make up the excretory system in humans. The excretory system is responsible for removing waste and excess materials from the body. The kidneys (number 1) filter waste from the blood and produce urine. The lungs (number 3) remove carbon dioxide and other waste gases through breathing. The liver (number 4) processes toxins and produces bile to aid in digestion. The skin (number 5) eliminates waste through sweat. Therefore, these four organs are the ones that make up the excretory system.

The correct answer is 2-4-7-6-1-3-5. This sequence represents the pathway of the respiratory air in the human body. It starts with the nose (2), then goes to the pharynx (4), larynx (7), trachea (6), bronchi (1), bronchioles (3), and finally reaches the alveoli (5) where gas exchange occurs.

Lemak dalam proses penyerapan makanan akan dipecah menjadi asam lemak dan gliserol.

The correct answer is "urine primer". In the given question, it is stated that the image is of a nephron. A nephron is the functional unit of the kidney responsible for filtering blood and producing urine. "Urine primer" refers to the initial filtrate that is formed in the nephron. This filtrate contains waste products, excess water, and electrolytes that need to be eliminated from the body. Therefore, urine primer is the correct term to describe the substance produced in the nephron.

The correct answer is "Inspirasi menyebabkan diafragma berkontraksi." This is because during inspiration, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. This contraction of the diaphragm helps to increase the volume of the thoracic cavity, leading to inhalation.

The correct answer is "kardiak penghasil HCl." This means that the label X in the image above represents the cardiac region of the stomach, which produces hydrochloric acid (HCl).

The correct answer is "pertukaran gas oksigen dan karbondioksida secara difusi". This is because the passage mentions that the image shows a part of the lungs that functions as an excretory organ. The process that occurs in this part of the lungs is the exchange of oxygen and carbon dioxide through diffusion.

Asfiksi is the correct answer because it refers to a condition where there is a disruption in the transportation of oxygen to the tissues or a disruption in the utilization of oxygen by the tissues. This can lead to oxygen deprivation in the body, causing various symptoms and potentially life-threatening consequences.

The correct answer is 7, 6, 5, 4. This is because the dendrites, cell body, nucleus, and axon are all parts of a neuron. The dendrites receive signals from other neurons and transmit them to the cell body. The cell body contains the nucleus, which controls the functions of the neuron. The axon carries signals away from the cell body to other neurons or muscles. Therefore, the correct sequence of the mentioned parts is 7 (axon), 6 (nucleus), 5 (cell body), and 4 (dendrites).

Energi yang diperoleh dengan pernapasan berasal dari ATP. ATP (adenosine triphosphate) adalah molekul energi yang dihasilkan dalam proses respirasi seluler. Ketika makanan diubah menjadi energi melalui proses respirasi, ATP diproduksi dan digunakan oleh sel untuk menggerakkan berbagai aktivitas seluler. Jadi, ATP adalah sumber energi utama yang diperoleh melalui pernapasan.

When there is stimulation in a neuron, the stimulus is transmitted from the dendrites to the cell body (also known as the soma), and then it is further transmitted to the axon. This is because the dendrites receive signals from other neurons or sensory receptors and transmit them towards the cell body, where the integration of these signals takes place. Once the integration is done, the signal is passed along the axon to other neurons or effector cells.

If part number 5 is damaged, it can lead to an easy infection in the middle ear.

The correct answer is 3-2-4-7-5-1-6. This is the correct sequence of the organs in the human digestive system. The process starts with the mouth (3), followed by the esophagus (2), then the stomach (4), small intestine (7), large intestine (5), and finally the anus (6).

Based on the data in the table, it can be concluded that the food ingredient contains amilum (starch) first, followed by glukosa (glucose), and then protein.

Based on the given information, the correct answer for the question is "ulkus". This is because ulkus refers to an ulcer, which is a sore or open wound that forms in the lining of the digestive tract. The question mentions that the image is showing a specific part of the digestive system, and ulkus is a common disorder that can occur in that area.

The correct answer is 3-4-1-2-3-4-5-7-8-6. The order of the food in the digestive system of ruminant animals starts with the mouth (3), then it goes to the rumen (4), then to the reticulum (1), then to the esophagus (2), then back to the rumen (3), then to the reticulum again (4), then to the omasum (5), then to the abomasum (7), then to the small intestine (8), and finally to the anus (6).

The correct answer is mitosis, meiosis 1, meiosis 2. This is because in mitosis, the cell undergoes one round of division to produce two identical daughter cells. In meiosis 1, the cell undergoes another round of division, resulting in the formation of two haploid daughter cells with half the number of chromosomes. Finally, in meiosis 2, each of the haploid daughter cells from meiosis 1 undergoes another round of division to produce four haploid daughter cells. Therefore, the correct sequence of events is mitosis, meiosis 1, meiosis 2.

The frequency of respiration is influenced by several factors including gender, body temperature, body weight, body position, and physical activity. However, body weight does not have a direct impact on the frequency of respiration. Therefore, the correct answer is body weight.

The urine test showed a positive result for glucose and protein, indicating kidney damage. The tubulus kontortus proksimal is responsible for reabsorbing glucose and protein from the filtrate back into the bloodstream. Therefore, if there is damage to the tubulus kontortus proksimal, it can lead to the presence of glucose and protein in the urine.

Sakus pneumatikus adalah alat pelengkap pernapasan pada aves yang digunakan untuk mengatasi kebutuhan oksigen saat terbang. Sakus pneumatikus merupakan kantung udara yang terhubung dengan paru-paru dan terletak di dalam tulang belakang burung. Kantung udara ini berfungsi untuk menyimpan udara tambahan yang akan digunakan saat terbang, sehingga aves dapat mengambil oksigen dari udara yang tersimpan di dalam sakus pneumatikus selama terbang. Dengan adanya sakus pneumatikus, aves dapat memiliki pasokan oksigen yang cukup saat terbang dalam jarak yang jauh atau dalam kondisi yang membutuhkan energi ekstra.

The correct answer is 1. spermatogonium, 4. spermatid. Spermatogenesis is the process of sperm cell development in the testes. It begins with spermatogonia, which are diploid cells that undergo mitosis to produce more spermatogonia or differentiate into primary spermatocytes. The primary spermatocytes then undergo meiosis I to form secondary spermatocytes, which then undergo meiosis II to form spermatids. Spermatids are haploid cells that further differentiate into spermatozoa or sperm cells. Therefore, the correct labels for the stages shown in the diagram are spermatogonium and spermatid.

The correct answer is "udara suplementer." Udara suplementer adalah udara tambahan yang dapat dihirup setelah inspirasi normal. Ini adalah udara yang dapat diisap dengan maksimal setelah inspirasi normal dan sebelum kapasitas vital tercapai.

The capacity of the lungs refers to the maximum amount of air that can be held in the lungs. It does not directly affect the binding of oxygen to hemoglobin. The other factors listed, such as oxygen levels, differences in oxygen levels in tissues, carbon dioxide levels, and oxygen pressure, all play a role in the binding of oxygen to hemoglobin.

The correct answer is "pengaturan keserasian proses dalam tubuh". This refers to the coordination and regulation of various processes within the body to maintain homeostasis and ensure proper functioning. It involves the integration of different systems, such as the nervous system, endocrine system, and immune system, to ensure that all processes work together harmoniously.

Ovulasi dan fertilisasi terjadi pada bagian 3 dan 5 dalam gambar sistem reproduksi.

Vasektomi adalah salah satu cara kontrasepsi yang dilakukan pada pria. Prosedur ini melibatkan pemotongan atau penyumbatan tabung yang menghubungkan testis dengan saluran ejakulasi, sehingga sperma tidak dapat mencapai saluran reproduksi wanita saat ejakulasi terjadi. Dengan demikian, vasektomi secara efektif mencegah kehamilan.

The correct answer is "Banyak garam yang dikeluarkan". This is because the question asks for a factor that does not affect the amount of urine excretion. The other options, such as the amount of water consumed, ADH hormone, insulin hormone, and emotional factors, can all have an impact on urine production. However, the amount of salt excreted does not directly affect the amount of urine excreted.

After leaving the testes, spermatozoa are stored and matured in the epididymis before being transported through the vas deferens. The epididymis is a coiled tube located on the back of each testicle, where the spermatozoa undergo a process of maturation and gain the ability to swim. Once matured, the spermatozoa are then transported through the vas deferens to the urethra for ejaculation. Therefore, the epididymis is the correct answer as it is the structure where spermatozoa are stored and matured before being transported.

The correct answer is 5, 6, 7. In the given image of the nephron, the sections numbered 5, 6, and 7 represent the parts of the nephron responsible for reabsorbing useful substances and producing secondary urine. These sections include the proximal convoluted tubule (number 5), the loop of Henle (number 6), and the distal convoluted tubule (number 7). Reabsorption of water, glucose, amino acids, and ions occurs in these sections, while waste products and excess substances are further eliminated to produce urine.

The correct answer is LH. LH, or luteinizing hormone, plays a crucial role in the maturation of the egg within the follicle. It stimulates the final stages of follicle development and triggers ovulation, the release of the mature egg from the follicle. LH also helps in the formation of the corpus luteum, which produces progesterone to prepare the uterus for potential implantation of a fertilized egg.

Estrogen dan oksitosin adalah hormon yang membantu proses kelahiran dengan merangsang kontraksi uterus. Estrogen membantu mempersiapkan rahim untuk kelahiran dan meningkatkan sensitivitas terhadap oksitosin. Oksitosin, di sisi lain, adalah hormon yang merangsang kontraksi otot-otot uterus selama persalinan. Kombinasi dari kedua hormon ini bekerja bersama-sama untuk memfasilitasi proses kelahiran.

The correct answer is 5 because in the given image, number 5 represents the sweat glands, which are responsible for excretion in the skin. Sweat glands help in regulating body temperature by secreting sweat, which contains waste products such as urea and salts. This excretion process helps in removing toxins and maintaining the chemical balance in the body.
