<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
The independent variable is the variable that is controlled by you, and the dependent variable is the variable that changes AS A RESULT of the changes you made to the independent variable.
In this case, Joan is controlling the gender, thereby changing the ability to empathize.
Therefore, the independent variable is gender and the dependent variable is the ability to empathize.
Answer
Elastin fibers are glycoproteins found in the lungs and are usually in large quantities. The abundant elastin fibers are helpful in the recoil process of the lungs after being expanded by the muscles of the respiratory system.
During inhalation,the diaphragm and intercostal muscles expand the chest. This forms a negative pressure and draws the air in.The Lungs recoil to expel used up air during exhalation.
