Question 1 a) DNA replication is the process in which a cell passes this DNA sequence onto other cells when it divides which is known as mitosis as it must duplicate its genome so each new cell has a copy. This occurs during interphase. During DNA replication the enzyme DNA helicase are important as they separate double-stranded DNA into single strands allowing each strand to be copied. DNA polymerase are another important enzyme that starts attaching new complementary nucleotides to these templates. It is done according to the base pairing rules, A=T, C=G, G=C and T=A. Once the new nucleotides are attached, two new sister DNA strands are formed same as the original strand. The result is two identical strands, each of which is half new. b) mRNA is a translation of DNA into a convertible protein substituting T with U. The template strand shown is the 1st step of transcription and it is transcribed to: GTA GAT TGG GGT CTC CTC. Each of the codons codes for a particular amino acid. For example, each codon is a triplet and codes for one amino acid. In the strand shown it separates it into triplets that will reveal codon and amino acid number. For example, CAT CTA ACC CCA GAG GAG = 6 amino acids. c) Sickle cell anaemia – GTA GAT TGG GGT CAC CTC Normal haemoglobin – GTA GAT TGG GGT CTC CTC While comparing the difference between the normal and sickle cell strands, it was identified that in the sickle cell there is a coding error.

We Need More Engagement Around Here - 765 Words

The Problem The employee motivation and engagement in the company is poor. Lots of workers are easygoing and apathetic. Only few of the employees give effort in their job. They also say that they were not able to learn and grow in the past year. Many employees say that they are satisfied with their salary and benefits however, only few of them are willing to stay in the company for at least three years. They are not motivated and showed no interest which leads to poor performance of their job. This could worsen if no proper actions would be taken. Areas to consider The company has both strengths and weaknesses; some of their strength is the following: †¢ The employees know what they are expected at work. The†¦show more content†¦Recognition is such a potentially powerful motivator. This could be done by giving recognition to the most industrious employee of every month, and selecting one most industrious employee for the year. Rewards can be a simple gift certificate or a custom-made plaque of recognition. Alternative 3: Teambuilding Another action would be to set up teambuilding activities to increase teamwork. Team building is pursued via a variety of practices, and can range from simple bonding exercises to complex simulations and multi-day team building retreats designed to develop a team. Team building is an important factor in any environment, it aims to bring out the best in a team to ensure self development, positive communication, leadership skills and the ability to work closely together as a team to solve problem. Teambuilding could also improve the individual relationship between employees. This alternative can be the preliminary action to take. Alternative 4: Learning environment The last but not the least action to take is to provide a learning environment for employees. The workplace must be a place for growth and learning.

Rising Sea Level Essay Example For Students

Rising Sea Level Essay Rising Sea LevelRising sea levels have been disturbing geographers and geologists forsome time now. Scientists are constantly trying to prevent the effectsrising waters are causing, which mainly includes beach and island erosion. So far, their attempts with man-made development on beaches along the easterncoast of America have only made things worse. Up and down the U.S. coast, public money is subsidizing private propertyon islands made of sand, the stuff on which, as the Bible says, only foolsbuild (Ackerman 7). In recent years there has been a trend towards livingon the barrier islands of Americas Atlantic Coast. High rise condominiums,numerous shops, and several businesses have been built to sustain largepopulations on these islands and continue to be built. As a result, thisvital chain of islands that lies between the ocean and the mainland areat risk. While interfering with the natural configuration of these islands, humanconstruction has advanced the rate of beach erosion, thus leaving the mainlandwith no barriers during times of high surf. This effect has also led tocostly, unnatural ways to preserve the barrier islands. Saving these islandsin their natural state by curbing human encroachment will both protectmainland populations from high surf and save a considerable amount of federalmoney. The barrier islands are a chain of islands, stretching from NewYork to southern Texas, that have served as a critical barrier from theAtlantic Ocean for well over the past 4,500 years (Ackerman 23). These islands however are not as stable as those who live on them wouldlike it to be. Beaches, and in fact whole islands, are constantly erodedas they are subjected to varying winds, currents and changing sea levels. Along Floridas East Coast, roughly 368 miles, the average shoreline changeis retreating 22cm per year. Under natural conditions, native vegetationand shifting sands constantly replace or withhold sand on the islands (16). Unfortunately for the inhabitants of the barrier islands, this is a geologicalbehavior which can only continue if the islands remain in a natural state. In recent years humans on these shorelines and islands have been respondingto the naturally changing conditions, through the use of man made structuressuch as seawalls, groins, and sand replenishment, in an effort to savebeachfront property from erosion. Obstructing the natural shifts of the islands, says Orrin Pilkey ofDuke University who has studied these islands for thirty years, will causethem to, be lost forever (16-17). Attempting to hold beaches in placewith the use of seawalls, groins, and sand replenishment may seem likea good solution in theory, but in practice they probe ineffective. Oneof the most common methods of attempting to hold barrier island beachesin place is through the use of sea walls, which are costly and ineffective. Seawalls are typically cement walls constructed parallel to the seashorein an effort to block waves from coming over the beach and into property. However, seawalls tend to withhold sand behind the wall during times ofhigh surf and the natural tendency of the beach to respond to waves isdisturbed (Kaufman 207). The structures commonly fail from undermining or erosion by waves breakingover their tops. Under normal conditions sand would be spread out by outgoingcurrents, which in turn would lower the slope of the beach and cause thewaves to break gradually. With seawalls in place, sand remains stationarywhile waves erode the beach as wave energy is deflected against sand notprotected by the seawall (208). In addition to advancing the erosion rateof the sand and inhibiting the beaches natural tendencies, seawalls havebecome quite costly to maintain. For example, in New York $120 millionwas paid by the federal government to sustain and replenish seawall installationsas of 1996, and repairs continue to be made (Dixon 231). Clearly, thismethod is both costly and ineffective. Another commonly used method ofstopping erosion is the placement of groins, which are also ineffective. .u36cc8f02e246052aade49e159c675e91 , .u36cc8f02e246052aade49e159c675e91 .postImageUrl , .u36cc8f02e246052aade49e159c675e91 .centered-text-area { min-height: 80px; position: relative; } .u36cc8f02e246052aade49e159c675e91 , .u36cc8f02e246052aade49e159c675e91:hover , .u36cc8f02e246052aade49e159c675e91:visited , .u36cc8f02e246052aade49e159c675e91:active { border:0!important; } .u36cc8f02e246052aade49e159c675e91 .clearfix:after { content: ""; display: table; clear: both; } .u36cc8f02e246052aade49e159c675e91 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u36cc8f02e246052aade49e159c675e91:active , .u36cc8f02e246052aade49e159c675e91:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u36cc8f02e246052aade49e159c675e91 .centered-text-area { width: 100%; position: relative ; } .u36cc8f02e246052aade49e159c675e91 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u36cc8f02e246052aade49e159c675e91 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u36cc8f02e246052aade49e159c675e91 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u36cc8f02e246052aade49e159c675e91:hover .ctaButton { background-color: #34495E!important; } .u36cc8f02e246052aade49e159c675e91 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u36cc8f02e246052aade49e159c675e91 .u36cc8f02e246052aade49e159c675e91-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u36cc8f02e246052aade49e159c675e91:after { content: ""; display: block; clear: both; } READ: Pearl Harbor - The United States Should Have Antic EssayGroins are pilings of rocks that extend into the ocean and perpendicularto the shore. Like seawalls, the primary purpose of a groin is to trapsand, but in longshore currents rather than sand deposits already on thebeach. Contrary to their intended purpose, these structures trap sand on theside facing a longshore current and leave the opposite side without sand(Kaufman 207). Over time, the side not facing longshore currents erodesand the initial problem reoccurs. Once again, after the unsuccessful useof groins, money and resources must be spent to restore the beach. A recentmethod of stopping erosion, and perhaps the most expensive, is that ofsand replenishment. Sand replenishment uses dredging techniques to pipesand from offshore deposits to the beach in an attempt to replace sand. This operation is also costly and the sand is usually lost in a major storm. Renourished beaches have a shorter life due to compaction and sea bottomimbalance differences. One example of its cost is that of Sea Bright beachwhere, at one million dollars a square mile; their beach was replenished(Ackerman 29). The total cost of this operation, which lasted between 1994 and 1996,was $36 million (29). These are just a few of the myriad of inadequateattempts to stop seashore erosion. Not only do these human obstructionsto the natural course of nature cause an accelerated erosion, millionsof government dollars are being lost in the process of attempting to savebeach front property from natural erosion. There are over 90 Federal navigationprojects and 21 Federal shore protection projects in Florida alone. Theseprojects have an annual maintenance cost of $32 million. Stephen Leatherman,head of the Coastal Research laboratory at the University of Maryland,suggests that, In nourishment projects locals pitch in about5 percent, state and county tax payers pay about 30 percent, and the federalgovernment pays the rest (Ackerman 30). Apparently, at the cost of theAmerican government, large sums of money are being spent on these futileefforts to stop natural occurrences. Recently in the past few years, anew attribute has been looked at. A bulge formed by Ice Age glaciers isslowly settling, while the mid-Atlantic coast is falling. In many places,the sea is taking back the land at the rate of about an inch every 25 years. Originally, scientists pondered why the sea level was rising fasterbetween Florida and New York than farther north. They hypothesized thatit must have been a shift in the Gulf Stream, but this new research showingthe fall of the land proved them wrong. Regardless, sea levels continueto rise and scientists are running out of ideas to prevent this from happening. Global sea level has risen 4 to 10 inches during the past 100 years becauseof global warming. By year 2050, a 16-inch sea-level rise is projected. Consequences of a higher sea-level to our coastal areas have not only includederosion, but some believe other effects it will have will include: tourism,the availability of drinking water, and damage from storms. The only effectivesolution that seems practical at the moment, without risking such largesums of money, is that human occupations of these islands become restricted. In most cases, people probably come to the seashore for recreation andrarely for necessity. Why not just live minutes away on the mainland andavoid having millions of dollars being spent on keeping beachfront propertyfrom washing away? This way federal money currently being spent on coastalprojects, such as seawalls, groins and sand replenishment, can be allocatedto more pressing problems of our nation. Until another economical solution,which does not contribute to the problem of erosion, is possible peopleshould minimize residential development on the barrier islands before boththe beaches and money wash away. .u63398d287d8307d142d1aaca76c8bf3b , .u63398d287d8307d142d1aaca76c8bf3b .postImageUrl , .u63398d287d8307d142d1aaca76c8bf3b .centered-text-area { min-height: 80px; position: relative; } .u63398d287d8307d142d1aaca76c8bf3b , .u63398d287d8307d142d1aaca76c8bf3b:hover , .u63398d287d8307d142d1aaca76c8bf3b:visited , .u63398d287d8307d142d1aaca76c8bf3b:active { border:0!important; } .u63398d287d8307d142d1aaca76c8bf3b .clearfix:after { content: ""; display: table; clear: both; } .u63398d287d8307d142d1aaca76c8bf3b { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u63398d287d8307d142d1aaca76c8bf3b:active , .u63398d287d8307d142d1aaca76c8bf3b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u63398d287d8307d142d1aaca76c8bf3b .centered-text-area { width: 100%; position: relative ; } .u63398d287d8307d142d1aaca76c8bf3b .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u63398d287d8307d142d1aaca76c8bf3b .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u63398d287d8307d142d1aaca76c8bf3b .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u63398d287d8307d142d1aaca76c8bf3b:hover .ctaButton { background-color: #34495E!important; } .u63398d287d8307d142d1aaca76c8bf3b .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u63398d287d8307d142d1aaca76c8bf3b .u63398d287d8307d142d1aaca76c8bf3b-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u63398d287d8307d142d1aaca76c8bf3b:after { content: ""; display: block; clear: both; } READ: Hitler And Stalin EssayBibliography Ackerman, Jennifer.

Sir Isaac Newton Essays (1212 words) - Classical Mechanics

Sir Isaac Newton Topics in Geometry A Research Project Presented To The Department Of Mathematics Of Thomas Edison High School In Partial Fulfillment Of The Course In Geometry Sir Isaac Newton was born on January 4, 1643, in Woolsthorpe, near Grantham in Lincolnshire. He went to Grantham grammar school. When he was young, he was interested in mechanical devices than in studying. His youth inventions included, a water clock and a sundial. Isaac's father had died when he was three years old and left the family with little money. His widowed spouse soon remarried, leaving Isaac in the of his grandmother. She had three more children and widowed a second time. Since Isaac paid little attention to the family farm because he spent so much time reading, he was sent back to grammar school in Grantham. Later, in the summer of 1661, he went to Trinity College, at the University of Cambridge. He learned of the scientific revolution that had been going on in Europe through the work of Galileo, Nicolaus Copernicus, Johannes Kepler, and Ren? Descartes. Newton received his bachelor's degree in 1665. Two years later after avoiding the plague, Newton return to Trinity College where he was elected to a fellowship in 1667. Newton received his master's degree in 1668. Newton retracted much of the established curriculum of the university to pursue his interest such as mathematics and natural philosophy. Continuing entirely on his own, he analyzed recent developments in mathematics and natural philosophy. Eventually, he made discoveries that played an important part in his career in science. He became Professor of Mathematics at Cambridge in 1669. He lectured once a week on Geometry, astronomy, optics, arithmetic, or other mathematical subjects. Three years later he invented the reflecting telescope. In 1687 he published his work, ?Principia'(Mathematical Principles of Natural Philosophy), setting forward the theory of gravity. In 1696 Newton was named warden of the mint where at that time a complete recoinage and standardization of coins were taking place. When the project was finished in 1699, he was made master of the mint. He was elected president of the Royal Society in 1703 and was knighted in 1705. Newton also engaged in a vicious argument with Leibniz over the priority of the invention of calculus. The effects of the quarrel inevitably lend to his death. Newton died in London on March 20, 1727, and was honored with a burial. Accomplishments One of Isaac Newton greatest achievement was the three laws of motion. Despite these three laws, they are not related to things such as air resistance or other kinds of friction. Newton's first law states that any body moving uniformly in a straight line of in a state of rest will remain in uniform motion in a straight line or in a state of rest unless it is acted upon by some outside force. This means when in motion you will remain in motion or if in a state of rest you remain at rest unless you are move by something. When kept in motion when in motion or at rest, it is called inertia. Whenever in motion, both acceleration and deceleration require subduing the inertia of an object. Newton's second law of motion states what happens when a force is applied to a moving body. The change in motion depends on the force on the object. It also depends on the size of the force and the mass of the object. The greater the force, the greater the acceleration and the greater the mass of the object, the smaller the acceleration. Acceleration or deceleration of an object depends on the direction of the force. The effects of two or more forces moving on the path of an object are determined by means of vectors. A vector is the of force and direction in which it moves. Forces acting on a single point are called concurrent forces. Suppose a rowboat is being pulled forward along a shore of a lake by someone. At the sametime, someone else in the rowboat uses an oar to push the boat away from the shore. This is an example of concurrent forces. Newton's third law of motion states that for every action there is an equal and opposite reaction. This is a perfect example
