The kidney is considered a major homeostatic organ because it maintains the balance of water, ions, and electrolytes in the blood.
Kidneys extract wastes and excess fluid from the body, kidneys also remove acid that is created by the cells in the body and sustain a healthy equilibrium of salts, water, and minerals like sodium, potassium, calcium, and phosphorus in the blood.
Each kidney consists of almost a million filtering units called nephrons. Every nephron has a filter, called the tubule, and a glomerulus. The nephrons function via a two-step process, the glomerulus purifies the blood, and the tubule returns required substances to the blood and clears wastes.

Answer:
D. Fossil record.
Explanation:
The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.
