The urinary system helps to maintain the balance of water and electrolytes in the body, aiding in the body's homeostasis. This is achieved through the filtration of the blood by the kidneys, expelling excess substances and waste products.
The urinary system plays an integral role in our body's homeostasis by maintaining the balance of water and electrolytes (Option B). This is accomplished by filtration of the blood in the kidneys, which remove waste products and excess substances, including water and electrolytes. For instance, if our body has a high level of sodium, the kidneys filter out the excess and excrete it into the urine. Similarly, if there is too much water, it will also be excreted. This delicate balance ensures our cells can function properly in the correct environment.

LEDs emit light because of heat; fluorescent bulbs emit light because of energized solids.
LEDs emit light because UV light interacts with a phosphor coating; fluorescent bulbs emit light by concentrating wavelengths of light.
Answer: A magnet has two poles that is north pole and south pole. From the directional property of the magnet, we know that whenever a magnet is freely suspended, it is always aligned along the north and south direction of the earth.
It can also be identified using a test magnet whose poles are already known. From attraction property of magnet, we know that unlike poles attract with each other and like poles repel each other. Therefore, the pole of unknown magnet that attract to the south pole of the known magnet will be north pole and the other will be south pole.
Thus, by freely suspending the magnet and by using a test magnet, the unmarked poles of the magnet could be easily identified.
