40) Describe the structure of a mammalian respiratory system. Include in your discussion the mechanisms of inspiration and expiration. In mammals‚ oxygen first passes through the nasal cavity. The nasal cavity is covered with mucus and cicilia to filter the air. The nasal cavity leads to the pharynx. The pharynx consists of the eustachian tube and the tonsils. The inhaled air then passes to the larynx‚ trachea‚ and bronchi. The bronchi lead to the bronchioles in the lungs. In the lungs the pleural

States. There were many causes that led to this pivotal moment in history. The main causes of this war were: the 1850 Compromise‚ the Fugitive Slave Act‚ Dred Scott’s Decision‚ and John Brown’s Raid. The 1850 Compromise was the earliest cause of the Civil War. Henry Clay proposed the 1850 Compromise to solve slavery‚ as the nation is growing larger. There was a new fugitive slave act in 1850 to appease the South‚ as California entered as a free state to appease the North. Abolitionist Daniel Webster

States. During 1803 to 1850‚ the U.S continued to expand‚ and the expansion is called “The Westward Expansion of the United States”. The forefathers decided to expand their territory due to their wish to start new lives‚ their belief in “Manifest Destiny”‚ and their desire to spread slavery. To begin with‚ on no account should we ignore the fact that lands are essential to a nation. So the U.S need to expand their territory to start new lives. “To Jefferson‚ westward expansion was the key to the nation’s

EXPERIMENT 1: ISENTROPIC EXPANSION PROCESS Objectives: 1) To demonstrate the isentropic expansion process. Introduction: In thermodynamics‚ an isentropic process is a process in which the process takes place from initiation to completion without an increase or decrease in the entropy of the system. One example of a process that approaches being isentropic are the rapid depressurization of gas in a cylinder. The entropy of the system remains in constant. Entropy is a type of energy

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Coefficient of Linear Expansion Introduction With few exceptions materials expand somewhat when heated through a temperature range that does not produce a change in phase (i.e. melting‚ freezing‚ boiling etc.). The added heat increases the average amplitude of vibration of the atoms in the material‚ which increases the average separation between the atoms. Although this effect is small‚ it is very important in any application that involves using different materials in an environment where they

The Fugitive Slave Act was one of the five acts contained in the Compromise of 1850. The highly controversial new law required the return of all runaway slaves to their masters. The recovery of runaway slaves was now under Federal Jurisdiction. Federal Marshalls were now bound by duty to return any runaway and also now had the authority to require assistance from any individual. If the assistance was not provided‚ the individual faced prosecution and fines. The law also stripped runaway slaves

comparison of Russia and Britain in the period 1850 – 1900. How true is it to say that Russia was a ‘backward country’?” Countries develop at different rates at different times. While Britain had started to industrialise and modernise prior to 1850‚ is it true to say that Russia was as successful in trying to develop before the start of the 20th century or were they still considered a backward country by that time? Prior to and during the period 1850 - 1900‚ Russia was controlled by a Tsarist autocracy
