<h3><u>Answer;</u></h3>
The permeability of the membrane
<h3><u>Explanation</u>;</h3>
- The fluidity and the permeability of cell membrane must be maintained within a certain range for the cell to function properly.
- The permeability of cell membrane depends on a number of factors, among them is the degree of saturation of fatty acids tails making up phospholipids.
- Phospholipid tails can be saturated or unsaturated. Saturated tails have no double bonds and as a result have straight, unkinked tails, while unsaturated tails have double bonds and, as a result, have crooked, kinked tails.
- Interactions between tails are maximized in the case of saturated tails, thus decreasing membrane fluidity and permeability, while unsaturated tails increases membrane fluidity.

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>
