Loam also contains 46 percent inorganic material such as sand, clay, and silt, and 4 to 6 percent organic materials in total
Explanation:
Answer: B. pressure changes in the thorax
Explanation:
The veins are the blood vessels which returns the deoxygenated blood from all the tissues and cells of the body back to the heart. The ventricular systole, venous valves, activity of the skeletal muscles and neural control over venoconstriction all influence the movement of the blood in the venous.
The pressure changes in the thorax occurs due to inspiration and expiration. During the process of inspiration, the diaphragm below the lungs contracts and moves downward while the muscles of the ribs pulls downward. When the size of the thoracic cavity increase the air pressure inside the cavity decreases and vice-versa. The pressure inside the thoracic cavity is not related with the movement of the venous blood as it regulates the exchange of the gases not the blood.
A virus first has to be able to get into a cell. But it can only do this if its antigen fits into one of the cells receptors. Depending on how much the cell has and of different types. Once the virus is in it replicates its DNA and proteins. Then these assemble and make even more viruses. The viruses then leave the cell. And all the viruses go off to infect a new cell and replicate more viruses.
