Secretion is the process in urinary system that leads to the elimination of excessive substances like sodium and potassium in the urine.
Secretion is the process of transfer of waste substances from the blood capillaries into the renal tubule. The waste substances can be ions like sodium, potassium, or hydrogen. The segment of the renal tubule that performs secretion is the proximal convoluted tubule.
Urinary system is also called the excretion system where all the waste ions, minerals and water is transferred out from the body in the form of urine.

Answer:
How can you know what happened millions of years ago if no one was there to see it? Evidence and observation are the building blocks of all scientific inquiry; ... of the fossil record, geological formations, and genetics attest to change having taken ... clues together into a cohesive explanation of the diversity of living things.

Even if they do leave fossils, humans may never find them—for example, if they are buried under hundreds of feet of ice in Antarctica.
