Breathing is largely driven by the muscular diaphragm, which divides the thorax from the abdominal cavity, forming a dome with its convexity towards the thorax. Contraction of the diaphragm flattens the dome, increasing the volume of the cavity in which the lung is enclosed. Air enters through the oral and nasal cavities; it flows through the larynx, trachea and bronchi and expands the alveoli. Relaxation of the diaphragm has the opposite effect, passively recoiling during normal breathing. During exercise, the abdominal wall contracts, increasing visceral pressure on the diaphragm, thus forcing the air out more quickly and forcefully. The rib cage itself also is able to expand and contract the thoracic cavity to some degree, through the action of other respiratory and accessory respiratory muscles. As a result, air is sucked into or expelled out of the lungs, always moving down its pressure gradient. This type of lung is known as a bellows lung as it resembles a blacksmith's bellows. Mammals take oxygen into their lungs, and discard carbon dioxide.
Increasing pressure on the diaphragm thus increasing air output more frequently is usually caused by?
****
The answer: exercise

This view reveals a somewhat less than altruistic Christian intent of the British Empire; however, it was paradoxical from the beginning, as Simpson and most other writers pointed out. The Ottomans were portrayed as the slavers, but even as the American and British fleets were striking at the Barbary pirates on behalf of freedom, their countries were promulgating a vigorous African slave trade of their own. Charles George Gordon is known as the saint of all British colonial officers. A dedicated Christian, he spent his time between assignments living among the poor and donating his salary on their behalf. He won Ottoman confidence as a junior officer in the Crimean War. In his later career he became a high official in the Ottoman Empire, working as Governor of Egypt for the Ottoman khedive for the purpose of conducting campaigns against slavers and slavery in Egypt and the Sudan.
What did he become in his later career?
****
The answer: a high official in the Ottoman Empire

Today, most commercial web browsers are paid by search engine companies to make their engine default, or to include them as another option. For example, Google pays Mozilla, the maker of Firefox, to make Google Search the default search engine in Firefox. Mozilla makes enough money from this deal that it does not need to charge users for Firefox. In addition, Google Search is also (as one would expect) the default search engine in Google Chrome. Users searching for websites or items on the Internet would be led to Google's search results page, increasing ad revenue and which funds development at Google and of Google Chrome.
What other browser has Google as the default search engine?
****
The answer: Chrome

After the success of quantum electrodynamics, Feynman turned to quantum gravity. By analogy with the photon, which has spin 1, he investigated the consequences of a free massless spin 2 field, and derived the Einstein field equation of general relativity, but little more. The computational device that Feynman discovered then for gravity, "ghosts", which are "particles" in the interior of his diagrams that have the "wrong" connection between spin and statistics, have proved invaluable in explaining the quantum particle behavior of the YangMills theories, for example, QCD and the electro-weak theory.
Where did Feynman find success before moving to quantum gravity
****
The answer:
quantum electrodynamics
