The correct answer is "Membuang sampah metabolism". Ekskresi refers to the process of eliminating waste products that are produced during metabolism. This includes removing substances like carbon dioxide, urea, and excess salts from the body. Therefore, this option accurately describes the function of ekskresi in getting rid of metabolic waste.

Kebiasaan menahan buang air besar mengakibatkan penyerapan air di kolon menjadi berlebihan. Hal ini dapat menyebabkan sembelit, karena tinja menjadi keras dan sulit untuk dikeluarkan.

Essential amino acids are amino acids that cannot be produced by the body and must be obtained from external sources such as food.

The given correct answer suggests that according to Islamic views, urine therapy is permissible as long as it is the only available medicine. This implies that in exceptional circumstances where no other alternative treatment is available, the use of urine therapy may be allowed.

Jika kita mengunyah nasi secara terus menerus, maka akan terasa manis karena sebagian amilum dipecah menjadi glukosa. Selain itu, air ludah mengandung ptyalin yang merupakan enzim yang membantu dalam pemecahan amilum menjadi glukosa. Oleh karena itu, pernyataan yang benar adalah 2,4.

Udara komplementer adalah udara yang masih dapat dimasukkan ke dalam paru-paru setelah inspirasi normal. Ini berarti bahwa udara komplementer adalah jumlah udara maksimum yang dapat dihirup setelah inspirasi normal.

Makanan yang kita telan dapat bergerak maju perlahan-lahan karena adanya gerak peristaltik yang terdapat pada kerongkongan. Gerak peristaltik adalah gerakan kontraksi dan relaksasi otot yang berurutan, yang membantu mendorong makanan dari mulut ke lambung. Gerakan ini memungkinkan makanan untuk bergerak melalui saluran pencernaan dengan lancar dan efisien.

The correct answer states that reabsorption in the human kidney is the process of reabsorbing water and useful substances from the renal tubules. This process occurs after filtration in the glomerulus, where water and important molecules are filtered out of the blood. Reabsorption helps to maintain the balance of fluids and electrolytes in the body by reclaiming water and essential nutrients from the urine back into the bloodstream.

The correct answer is "Glomerulus." The biuret reagent is used to test for the presence of proteins in urine. If the biuret reagent turns purple, it indicates the presence of proteins in the urine, which can be a sign of kidney damage. The glomerulus is a part of the kidney that filters blood and removes waste products, including proteins, from the blood. Therefore, if the biuret reagent turns purple, it suggests that there may be a problem with the glomerulus and kidney function.

Hipo-ADH refers to a deficiency in antidiuretic hormone (ADH) production or release. ADH plays a crucial role in regulating the body's water balance by controlling the amount of water reabsorbed by the kidneys. In diabetes insipidus, there is a decrease in ADH levels, leading to excessive urination and thirst. This condition can be caused by various factors such as damage to the hypothalamus or pituitary gland, medications, or genetic factors. Therefore, the correct answer suggests that diabetes insipidus is caused by a deficiency in ADH production or release.

Consuming tea after a meal should be avoided because it can inhibit the absorption of iron, which plays a role in the formation of hemoglobin. Therefore, the correct answer is Fe, which is the chemical symbol for iron.

When the diaphragm contracts, it causes the chest cavity to expand. This expansion creates a negative pressure in the chest cavity, causing air to rush into the lungs to equalize the pressure. Therefore, the correct statement is that when the diaphragm contracts, the chest cavity expands and air enters the lungs.

The patient's yellowish blood color and grayish brown feces suggest that there may be a blockage in the bile ducts or bile drainage system. This obstruction can prevent the normal flow of bile from the liver to the intestines, resulting in the accumulation of bilirubin in the blood and the excretion of pale-colored stools.

The increase in lactic acid levels in muscles occurs when there is a lack of oxygen. Oxygen is essential for the process of aerobic respiration, which produces energy in the form of ATP. When there is insufficient oxygen available, the body resorts to anaerobic respiration, which produces lactic acid as a byproduct. This buildup of lactic acid leads to muscle fatigue and discomfort.

When the heart does not produce bile, it will result in digestive disorders, specifically in the digestion of fats. Bile, produced by the liver and stored in the gallbladder, helps in the emulsification and breakdown of fats in the small intestine. Without bile, the digestion of fats becomes impaired, leading to difficulties in absorbing and processing dietary fats. This can cause symptoms such as indigestion, bloating, and diarrhea. Therefore, the correct answer is "Pencernaan lemak" which means "Digestion of fats" in English.

The pancreas is considered as an exocrine gland because it produces enzymes such as amylase, lipase, and trypsin that are involved in digestion. On the other hand, it is also an endocrine gland because it produces hormones like insulin and glucagon that regulate blood sugar levels.

When glucose is metabolized in the presence of oxygen (O2), it undergoes a process called aerobic respiration. During this process, glucose is broken down into carbon dioxide (CO2), water, and energy. This is the most efficient way for the body to produce energy.

The correct answer is "Permukaan dalam yang berbelit-belit". The inner surface of the small intestine is lined with tiny finger-like projections called villi, which increase the surface area available for absorption. These villi greatly enhance the absorption of nutrients from digested food.

The correct answer is that the pressure of oxygen particles in the alveoli is higher than in the blood. This is because during respiration, oxygen diffuses from the alveoli into the capillaries of the blood. Diffusion occurs from an area of higher concentration to an area of lower concentration, so the higher pressure of oxygen particles in the alveoli drives the movement of oxygen into the blood.

Hati berfungsi dalam pemeliharaan konsentrasi gula darah dengan menyimpan gula dalam bentuk glikogen dan melepaskannya saat dibutuhkan. Hati juga berperan dalam detoksifikasi bahan-bahan berbahaya dengan mengubahnya menjadi zat yang lebih aman. Selain itu, hati juga memproduksi limbah bernitrogen dalam bentuk urea. Namun, hati tidak terlibat dalam osmoregulasi dalam berbagai ekskresi garam.

During anaerobic respiration in human cells, glucose is broken down into two molecules of lactic acid, and only a small amount of ATP is produced. This is because anaerobic respiration does not involve the use of oxygen, which is required for the complete breakdown of glucose and the production of a larger amount of ATP. Therefore, the correct answer is 2 mol asam laktat + 2 ATP.

When we feel hungry, it is because our blood sugar levels decrease. This triggers a signal to our brain that we need to eat in order to replenish our energy levels.

The correct answer is "Pengeluaran feses oleh anus" because the other options mention the excretion of various substances through different organs. The liver excretes bilirubin and biliverdin, the lungs excrete CO2 and H2O, the skin excretes water, minerals, and a small amount of urea, and the kidneys produce urine. However, the excretion of feces occurs through the anus, not by the process of excretion.

When the body temperature increases due to exercise or being in a hot environment, several mechanisms are activated to cool down the body. These mechanisms include the dilation of blood vessels in the skin, activation of skeletal muscles, activation of the thermostat in the hypothalamus to initiate cooling mechanisms, and vasodilation of superficial blood vessels. The activation of sweat glands and increased sweating help in cooling the body through the process of evaporation.

The energy obtained from respiration is a result of the breakdown of glucose. Glucose is the primary source of energy for cellular respiration, where it is broken down through a series of chemical reactions to produce ATP, the energy currency of cells. This process occurs in the mitochondria, where glucose is oxidized to release energy that can be used by the cell for various metabolic processes.

Based on the given data, the Lugol reagent turned the initial brown color into a dark blue-black color, indicating the presence of starch (amilum). The Benedict reagent turned the initial light blue color into a brick red color, indicating the presence of glucose (glukosa). The biuret reagent turned the initial light blue color into purple, indicating the presence of protein. Therefore, the correct answer is Amilum, protein, glukosa.

The main function of the oxygen we inhale during breathing is to bind hydrogen from the body's metabolism.

Jika suhu tubuh di atas normal, metabolisme tubuh berlangsung cepat, bukan lambat. Ketika suhu tubuh meningkat, aktivitas enzim dalam tubuh juga meningkat, sehingga mempercepat metabolisme. Dalam kondisi ini, tubuh membutuhkan lebih banyak oksigen untuk mendukung proses metabolisme yang lebih cepat.

The correct answer is plasma darah dan sel-sel jaringan because pernapasan luar refers to the exchange of oxygen and carbon dioxide between the blood and the cells of the body. This exchange occurs in the capillaries, where oxygen from the plasma in the blood is delivered to the cells, and carbon dioxide produced by the cells is taken up by the plasma to be transported back to the lungs for elimination. Therefore, the exchange of oxygen and carbon dioxide occurs between the plasma in the blood and the cells of the tissues.
