Boeing B-17 Flying Fortress
The Boeing B-17 Flying Fortress is a four-engine heavy bomber aircraft developed in the 1930s for the United States Army Air Corps

The Boeing B-17 bomber was an innovative plane introduced by the United States military in 1938. It was the most durable plane of World War II, and completed many successful missions in its ten-year commission. This four-engine bomber was developed for the United States Army Air Corps
-4000 pounds of bombs
-it can go at least 2000 miles
-eight 50-calliber machine guns fight off enemy air attacks
-it was tough, dourable, and it found a way to keep going (just like an American soldier)
- used in Rouen, the Germans’ biggest railway marshalling yard in northern France

The virtues of commitment and perseverance go hand in hand in all aspects of life, especially in relationships. Commitment gives you the desire to achieve your goals in life. You need to know what you want in order to become successful, and the focus you have comes from the virtue of commitment. You need perseverance to help you make it over the obstacles and setbacks that you are bound to face. These virtues should be the fuel to help you achieve your goals. As long as you are committed and persistent and have faith in God, anything is possible.

It wasn't until 1865 that an Augustinian Monk named Gregor Mendel found that individual traits are determined by discrete "factors," later known as genes, which are inherited from the parents. His rigorous approach transformed agricultural breeding from an art to a science. He started with parents of known genetic background — to provide a baseline against which to compare patterns of inheritance in the resulting offspring. Then he carefully counted the numbers of individuals showing the various traits in successive generations of offspring.

Earlier work had shown that DNA is composed of building blocks called nucleotides consisting of a deoxyribose sugar, a phosphate group, and one of four nitrogen bases —

    A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains, two in particular that compose a strain of DNA, are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base, a sugar, and a phosphate group make up the composition of a nucleotide. In the case of DNA, the four nucleotides that are found along the chain of DNA are thymine (T), cytosine (C), adenine (A), and guanine (G). Those nucleotides are joined by their covalent bonds, more specifically the sugars and phosphates which compose the sugar-phosphate backbone of the polynucleotide.…

    DNA made up of units called nucleotides, nucleotides are made up of three molecules components, a nitrogen base, a sugar, and a phosphate (Simon, Reece, Dickey, 2010). The nucleotides are joined together by bonds between the sugar of one nucleotide and the phosphate of the next producing a long chain of nucleotides resulting in a sugar-phosphate backbone (Simon, Reece, Dickey, 2010) the base containing nitrogen is the only part that is variable represented by, A Adenine, C cytosine, G guanine, and T Thymine. The sugars and phosphates form the backbone of the molecule and are on the outside. The bases point inwards horizontally. The antipoarallel strands run in opposite directions and are held together by hydrogen bonds between the base pairs, these two long strands twisted and wrap around each other to form a double helix. Hydrogen bonds between bases hold the strands together; each base pairs with a complementary partner: A with T, and G with C (Simon, Reece, Dickey, 2010).…

    Every major conflict the United States of America has fought in has had a defining characteristic that people identify with that era. From the Red Coats of the Revolutionary War to trench warfare of World War I, World War II also had a defining characteristic. One can make the argument that in World War II that defining characteristic was the use of aviation, most notably the bomber. One of the most iconic bombers of World War II was the B-17 Flying Fortress. This paper will explain what brought about the development of the B-17 and its inception, as well as the B-17’s role in combat and supporting ground troops. Lastly, discussed are the Memphis Belle and Old 666, two notable B-17’s from World War II.…

    DNA is long molecule made up of nucleotides. Each nucleotide has three parts: 5- carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base. The four nitrogenous bases are adenine and guanine, which are purines, and cytosine and thymine, which are pyrimidines.…

    A DNA molecule which is the abbreviation for deoxyribonucleic acid is made up of precise lengthy chains of polymers and monomers and they are called nucleotides. These two (2) chains specifically which are composed of DNA strain are then molded by the grouping of the nucleotides into the polynucleotides. The nucleotide is composed of a nitrogenous base, a phosphate and a group. In DNA there are four (4) nucleotides that can be found along the DNA chain. These four (4) nucleotides are (T) thyme, (A) adenine, (C) cytosine, and (G) guanine. These four (4) nucleotides are fused together by their covalent bonds. In other words the sugar and the phosphates which composes the sugar/phosphate support of the polynucleotide.…

    Well-known during WWII, P-51 Mustang was considered the world’s elite in aviation. Being the long range, single-seater bomber, this aircraft was exclusively used not only in WWII but also in Korean War. This fighter was considered as the best during its era. To say that this aircraft was great would be an understatement. Needless to say, if you want to have this legendary aircraft, you really have to pay through the nose as this cost more than…

    Since the beginning of World War I, key military analysts have begun to realize the importance of airpower over the battlefield. It has been said throughout the years that “he who controls the air, also controls the battlefield”. Though some have disputed this statement, the truth has always been proven to analysts after the war when evaluations can be made. The three branches of military that currently use fighter/bomber aircraft are the Air Force, Navy, and Marines. During the military’s vast aviation history, all three branches of service have used separate aircraft. In his book “Ultimate Fighter”, Bill Sweetman, an experienced aviation journalist, states that “if there was one element of Joint Advanced Strike Technology that aroused skepticism, it was the idea that one aircraft could work for every service” (42). That is exactly what the Joint Strike Fighter (JSF) program hopes to accomplish, but can it? The F-35 is attempting to do what many have failed at previously: meet the specific needs and requirements of all three service branches, incorporate years of compiled information into state-of-the-art equipment, and accomplish all this at a very competitive price.…

    Shortly after the first flight, wars broke out across the world. Immediately engineers tried to find a way to get an edge in a combat situation. This edge came in the way of aerial combat support for the troops on the ground. As the technology improved, the design, strength, and functionality of combat aircraft has improved. From the P-40 Warhawk, to the P-51 Mustang, to the F-4 Phantom, to the F-14 Tomcat, F-15 Strike Eagle, and F-16 Viper, the technology improved time and again, making air superiority a key part of American warfare.…

    When we hear the name Boeing, we automatically associate it with airplanes, but they are much more than that. They also manufacture military aircraft, which includes space technology and defense systems. William Edward Boeing began the Boeing Airplane Company in 1916 after the construction of a twin-float seaplane, known as B & W. William Boeing also made history with his biplane. This biplane was used to deliver the first international airmail from Vancouver to Seattle. The Boeing Company is organized into two business units: Boeing Commercial Airplanes and Boeing Defense, Space and Security (Boeing Corporation, 2007). These two units are supported by Boeing Capitol Corporation, Shared Services Group and Boeing Engineering, Operations and Technology.…
