I believe that ,Exhalation begins when the internal intercostal muscles contract.
Exhalation happens due to elastic properties of the lungs as well as the internal intercostal muscles which lower the rib cage and decrease the thoracic volume. As the thoracic diaphragm relaxes during exhalation it causes the tissue it has depressed to rise superiorly and put the pressure on the lungs to expel the air.
<h2>Biotic and Abiotic Factors Controls Viral Activity in Sea </h2>
Firstly, biotic are living components and abiotic are non living. Abiotic are the temperatures of ore and other items that are non-living. In the stream, the biotic factor can be small toads, shrubs, fish anything existing in the sea. In the sea, the biotic factors are any great fish or sea beings existing in that region including the any tiny bodies. In this way, all factors and components control viral activity in the sea.
The perivascular feet of the <u>endothelial cells</u> help create a blood-brain barrier.
<h3>What are endothelial cells?</h3>
Endothelial cells can be defined as those type of cells found in the inside lining of blood vessels, lymph vessels, and the heart.
Interestingly, the major function of the edothelial cells is that they release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.
So therefore, the perivascular feet of the endothelial cells help create a blood-brain barrier.

DNA is transcribed to RNA, which is translated into proteins. So DNA is in charge of making proteins (this narrows it down to either A or D). When there is a change in a person's genetic information, it will not result in a contagious disease. Those are usually caused by bacteria or viruses. A change in DNA could potentially result in a genetic disease. Therefore, answer A is correct. Hope this helps! :)
