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.

In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
<span>True predation is when a predator kills and eats its prey. Some predators of this type, such as jaguars, kill large prey. They tear it apart and chew it before eating it. Others, like bottlenose dolphins or snakes, may eat their prey whole. In some cases, the prey dies in the mouth or the digestive system of the predator. Baleen whales, for example, eat millions of plankton at once. The prey is digested afterward. True predators may hunt actively for prey, or they may sit and wait for prey to get within striking distance.
In grazing , the predator eats part of the prey but does not usually kill it. You may have seen cows grazing on grass. The grass they eat grows back, so there is no real effect on the population. In the ocean, kelp (a type of seaweed) can regrow after being eaten by fish.</span>
