Answer:
Law
Explanation:
A scientific law, is a statement that describes a principle of nature, they are also known as natural laws, and are generally always true.
Scientific laws are often mathematical formulas or expressions of natural events that occur, for example gravity.
Gravity is a natural event that occurs and it was put into a mathematical equation by Issac Newton

Scientific knowledge changes over time due to several factors. One major factor is the continuous accumulation of new evidence through scientific research.
As new experiments are conducted and data is gathered, it can challenge or refine existing theories, leading to updates in scientific knowledge.
Technological advancements also play a role in driving change, as they provide scientists with new tools and methods to explore and observe the natural world.
Additionally, scientific debates and discussions within the scientific community contribute to the evolution of knowledge, as different perspectives and interpretations are considered.
Overall, the dynamic and self-correcting nature of science allows for the continuous growth and improvement of our understanding of the world.

Production of urine
Explanation:
The three major steps in urine formation in the urinary system are – glomerular filtration,reabsorption and secretion – all of which results in removal of waste and excessive water from the body.
Kidneys are the main organs of the urinary system which takes part in the formation of urine. The kidneys are supplied by the renal arteries and capillaries. Each kidney consist numerous functional units called nephrons. Each nephron has a renal corpuscular and a tubular structure.
The renal corpuscle holds the Bowman’s capsule which contains the tuft of blood capillaries called the glomerulus. Glomerular filtration of blood plasma flowing in its capillary systems filters filterable components of blood like water and smaller solute particles leaving behind non-filterable blood cells, large proteins, etc. The filtered components gets collected in the glomerulus and forms the glomerular filtrate.
This filtrate then travels through the tubular structure – convoluted tubule and Loop of Henle, where reabsorption of water and nutrient ions takes place.
The remaining waste ions, and hydrogen ions are then collected in the collecting tubule. This is secretion of urine which then passes to the urinary bladder through the ureters.
