Answer:
<u>Negative Feed Back system -</u> " Some times an organ stops or interrupts a process or function in order to stabilize its self and the body, mainly the output or product of the process is lessened in order to control the situation such mechanism is known as negative feed back system."
Explanation:
<u>Negative feedback system in Lungs </u>
Now in lungs, the respiratory system maintains the normal partial pressure of the arterial oxygen and Carbon dioxide. As the partial pressure if exerted by them has a very high influence on the blood pH and can cause imbalance in the blood pH. So for this reason the negative feed back system is present.
As the body sends the message to the controlling hub of human body and then it starts the process of stabilizing the whole system back to normal by rearrangements of components or parts, along with secretion of some chemicals in the human body.
<em>Moreover a sketch is drawn which shows the feedback mechanism in a more simple way.</em>
Wind power or wind energy describes the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.

Explanation: Feral swine are not native to the Americas. They were first brought to the United States in the 1500s by early explorers and settlers as a source of food. Free-range livestock management practices and escapes from enclosures led to the first establishment of feral swine populations within the United States. In the 1900s, the Eurasian or Russian wild boar was introduced into parts of the United States for the purpose of sport hunting. Today, feral swine are a combination of escaped domestic pigs, Eurasian wild boars, and hybrids of the two.
Feral swine have been reported in at least 35 states. Their population is estimated at over 6 million and is rapidly expanding. Range expansion over the last few decades is due to a variety of factors including their adaptability to a variety of climates and conditions, translocation by humans, and a lack of natural predators.
Answer: DNA is sometimes enclosed inside an organelle called the nucleus. The nucleus is in a eukaryotic cell. It is a membrane bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction.
