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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is alveoli inspired by?
Ah, so.. unanswerable

In 1165 Maimonides visited Jerusalem and prayed on the Temple Mount, in the "great, holy house". In 1141 Spanish-Jewish poet, Yehuda Halevi, issued a call to the Jews to emigrate to the Land of Israel, a journey he undertook himself. In 1187 Sultan Saladin, founder of the Ayyubid dynasty, defeated the Crusaders in the Battle of Hattin and subsequently captured Jerusalem and almost all of Palestine. In time, Saladin issued a proclamation inviting Jews to return and settle in Jerusalem, and according to Judah al-Harizi, they did: "From the day the Arabs took Jerusalem, the Israelites inhabited it." Al-Harizi compared Saladin's decree allowing Jews to re-establish themselves in Jerusalem to the one issued by the Persian king Cyrus the Great over 1,600 years earlier.

In 1839, Melbourne resigned after Radicals and Tories (both of whom Victoria detested) voted against a bill to suspend the constitution of Jamaica. The bill removed political power from plantation owners who were resisting measures associated with the abolition of slavery. The Queen commissioned a Tory, Sir Robert Peel, to form a new ministry. At the time, it was customary for the prime minister to appoint members of the Royal Household, who were usually his political allies and their spouses. Many of the Queen's ladies of the bedchamber were wives of Whigs, and Peel expected to replace them with wives of Tories. In what became known as the bedchamber crisis, Victoria, advised by Melbourne, objected to their removal. Peel refused to govern under the restrictions imposed by the Queen, and consequently resigned his commission, allowing Melbourne to return to office.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which group was resisting the abolisment of slavery and were subsequently removed from power when the bill was voted down?
Ah, so..
plantation owners
