Genetically Modified Organisms ( Gmos ) - 1531 Words

Recently, the topic of genetically modified organisms (GMOs) has raised controversy in both the public and private sectors. Much of this relates to GMOs in food and crop and the potential consequences of consuming such produce on a large-scale basis as is becoming increasingly commonplace in the United States. These concerns, when coupled with the often concerning practices in animal feedlots, have begun to create almost a panic in the minds of consumers who find themselves questioning what they are eating. A greater understanding of genetically modified organisms, especially as it relates to food, is necessary for people to truly weigh the advantages and disadvantages of the increased use of GMOs. Genetically modified organisms, on a basic level, have existed for many centuries. The domestication of animals and early farming techniques modified organisms by breeding the creatures or plants that exhibited positive traits (Goldbas 20; Mahgoub 30). For example, farmers would crossbreed crops in hopes to increase yields or create healthier produce (Mahgoub 30). As technology advanced, scientists realized that fields like molecular biology could potentially make this process more efficient (Mahgoub 30). The idea was simple: if they could select the superior traits on a genetic level, they could create a better crop while avoiding the dangers of traditional crossbreeding such as spreading an unwanted trait (Mahgoub 30).

Classical Music Influences Our Bodys Vital Movements

Music of any genre or style that originates from a sincere and pure motivation, empowered not by the energies of one’s self, but rather by something greater, exists beyond time, culture, or history. ‘Classical’ music includes many principles that define the true meaning of the value of the classical sounds of music. Detail of the compositional structure and other technical aspects contribute to the most seemingly insignificant nuances. The structural integrity and balancing utilizing of tones create a linear timeline of the composition. Classical music affects us not only on an emotional level but on a neural level as well. Listening to classical music enhances the activity of genes involved in the release of dopamine. In addition, the†¦show more content†¦This ability is important for generating and conceptualizing multi-step problems. The purpose of this experimental study was to investigate the effect of The Mozart Effect: Music for Children collection on the social, cognitive, and physical development of five and six-year-olds. The music of Mozart was introduced into the children s environment as a sensory background for the standard curriculum because as children grow, their social, cognitive, and physical skills can be enhanced by their relationship with music. Many researchers have studied young children because their brains are in the process of developing. Young children are also innocent and are incapable for fully understanding the study being researched, therefore they do not have the capacity to control or manipulate the study. The study showed the effect of classical music on young children. Young children who listen to music regularly demonstrate better development than those who do not. The study focused on the development of kindergarten children; twenty-one children were exposed to classical music in their classroom setting, while the other twenty-one children were not exposed to music at all throughout their time in the classroom (Mattar et al., 2013). These young children range from five to six years in age. Young children who listen to music regularly demonstrate better

Art Evaluation Essay Example For Students

Art Evaluation Essay Firstly we started by looking at art by Georgia Okeefe who mainly painted abstract flowers this was a new style for me as I have never tried drawing in abstract style before, after this we did two paintings in acrylics one of shells and one piece of corn and around the edge of the paintings I then collaged in the background. This was a new way of doing backgrounds for me, as I have never tried using painting and colaging together. We have also tried a picture of natural objects with pastels then used chalk to make a grey background. I didnt really like the results of the chalk background because it was so dull. Then we did a picture of fruits in pencils and shaded them this piece was very similar to the pictures I made of fruits later in my book one in watercolour pencils and one I collaged. I was very pleased with my picture in watercolour pencils but the collage didnt turn out to well. After this I made a page of leaves drawn in 2 styles two in pencils and two in rubbings. I was pleased with the leaves done in pencil but the rubbings didnt look that nice as you can only get a single colour and no shading. Next continuing with the vegetation theme I made a picture of Monets water lilies. I was pleased with this as it allowed me to experiment with pastels and enabled me to create a strong colourful picture. Next we made a copy of a picture of Jesus on the cross in acrylic this painting was done by Gauguin. This enabled me to experiment with a new style of painting with its simple lines and bright colours. The next piece of art is the piece that Im happiest with out of my entire book. It was a copy of a print of black and white natural objects shaded with dots and lines. This was a completely new style of shading for me and it is one that I like a lot. Then I started developing my final art piece for the year I took a section of my garden and drew and shaded it in black pen after this I did 2 or 3 more pictures of this section of my garden one in pencil one in collage and one in acrylic. These were all to try and develop my picture but the only one I was really happy about was my first picture in black pen. I have also done a picture of feathers one set done in white pencil and coloured pencils on black paper, the other set was done in inks. Using inks was a completely new experience for me as was colouring on black paper I liked using both. Then I did another 2 pictures of natural pictures one of scallops in coloured pencils and one of horse chestnuts done in chalk and then I coloured in the background in grey chalk. After this we started concentrating on landscapes more. Firstly I made a picture of two trees one copied from Van Gogh and one of my own creations. I was very unhappy with both of these pictures I thin I could of improved them by spending longer on the backgrounds. Then carrying on with the landscapes theme we did 2 pictures of skies by famous artists one done watercolour a copy of a sky by Turner and one by Van Gogh in pastel. I was quite happy with both of these pictures and I liked making the strange effects of the Van Gogh sky with pastels. I also looked at the style of art noveau, which I found very interesting, and I was quite pleased with my picture in coloured pencils, the picture was of a design off fruits. I also did a picture again in acrylics, this was a copy of a painting fruits on a table by Paul Cezanne. Another piece of art I did in this book was a landscape picture by Katsushika Hokusai in an interesting Japanese style using blocks of colour and very bold lines. This was my other favourite piece of art it was an interesting picture of a large frothy wave. .u0c9f6de6d89788d8a916e60bcd5db9c4 , .u0c9f6de6d89788d8a916e60bcd5db9c4 .postImageUrl , .u0c9f6de6d89788d8a916e60bcd5db9c4 .centered-text-area { min-height: 80px; position: relative; } .u0c9f6de6d89788d8a916e60bcd5db9c4 , .u0c9f6de6d89788d8a916e60bcd5db9c4:hover , .u0c9f6de6d89788d8a916e60bcd5db9c4:visited , .u0c9f6de6d89788d8a916e60bcd5db9c4:active { border:0!important; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .clearfix:after { content: ""; display: table; clear: both; } .u0c9f6de6d89788d8a916e60bcd5db9c4 { 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; } .u0c9f6de6d89788d8a916e60bcd5db9c4:active , .u0c9f6de6d89788d8a916e60bcd5db9c4:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .centered-text-area { width: 100%; position: relative ; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .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; } .u0c9f6de6d89788d8a916e60bcd5db9c4:hover .ctaButton { background-color: #34495E!important; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0c9f6de6d89788d8a916e60bcd5db9c4 .u0c9f6de6d89788d8a916e60bcd5db9c4-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0c9f6de6d89788d8a916e60bcd5db9c4:after { content: ""; display: block; clear: both; } READ: Dress Code EssayI coloured it using watercolour and used fine liner for the edges of some of the waves. In the latter part of this year we also did some work on something called the mizu project where we worked around the theme of the river Thames and how important it is and we created constructions using different parts from our work so far this year and from our imaginations. I think my projects worked well especially the one I black and white. I created them by cutting out the thick cardboard making the images and sticking them on the pieces of cardboard then overlapping the cardboard and sticking that together. Then we started preparing for my exam so we did some work looking at Janet Fishs drawings of fruits glass and her bold use of colour and light, this was helpful in our exam as we were drawing sweets placed in a jam jar. It was a fairly difficult thing to draw firstly the reflections kept changing and with so many sweets within the jar it was difficult to draw them all the rights size and the jam jar was a difficult shape to draw as the top changed depending on where you looked at it from. I liked the way this picture came out I think I drew the glass reflections well but I think I should have used stronger colours with the sweets to make them stand out more against the black paper. Then I created my final construction which was a combination of everything from the first 2 and all my work earlier that year but this time we made everything on the construction rather than using photocopies, I was happy with the way my construction turned out and I liked the use of colour on it. I Feel that overall this year I could have done quite a bit better with some of my earlier pieces, most of the ones I messed up were in acrylic so I think that maybe next year I will do a bit better as I have had so much more practice at using them. While I did do some bad pieces there were quite few pieces I was happy with I was happy with all my pictures done in watercolour or watercolour pencils I also like the pictures that I have done using pastels. I have found this topic very interesting and it has enabled me to experiment with many new styles, materials and techniques.

Surface tension of water Essay Example

Surface tension of water Paper The capillary rise method was used to measure the surface tension of aqueous solutions of sodium chloride and acetic acid. Molar concentrations of 0. 5 M and 1. 0 M for each solution were tested. The results were then compared to the surface tension of pure water to observe how solute properties affect the surface tension of water. The experimental results showed that adding acetic acid solute in water lowers the surface tension of water. As the concentration of acetic acid was increased, the surface tension of water decreased even more. However, the experiment has failed to accurately show the effect of sodium chloride solutes on the surface tension of water. Nevertheless, previous studies revealed that surface tension of electrolyte solutions, such as NaCl solution, increase with increasing concentration. The experiment revealed several disadvantages of the capillary rise method, such as difficulties in firmly holding the equipment, in reading the liquid level inside the capillary, in keeping the temperature constant, and in accurately marking the liquid level with a pen. Nevertheless, the capillary rise method proved to be comparatively reliable, provided that proper technique is observed. Results of the capillary rise experiment for the effect of acetic acid somehow agreed with results from previous studies. INTRODUCTION Surface tension occurs due to cohesive forces (attractive forces acting between like molecules) pulling the surface molecules toward the body of the liquid. Furthermore, these surface molecules exhibit stronger cohesive forces upon neighboring molecules compared to the rest of the liquid.

From experience we also observe that it is more difficult to move an object through the surface of a liquid than to move it when it is completely submersed. In this study, the surface tension of dilute aqueous solutions will be measured. The study aims to examine how the surface tension of these solutions compare with that of pure water. The surface tension of water can vary due to the factors solute type (or substance dissolved), concentration of solution (i. e. amount of substance dissolved), and temperature. This study will focus particularly on the effects of solute type and concentration. Solute types of particular interest in this study are strong electrolytes, and low molar mass organic acids. (Another type of substance are surfactants, or surface active compounds, but they will not be covered in this experiment). Past scientific studies have concluded that electrolytes increase the surface tension of water slightly, while organic acids slightly decrease surface tension. These studies have made use of advanced methods with the help of special equipment called tensiometers. One such method is called the du Nuoy Ring Method, which measures the force needed to pull a ring up from the surface of a liquid. However, in this experiment the capillary rise method will be used for measuring surface tension. This procedure relates the elevation of the liquid inside the capillary tube with the surface tension of the solution. With this method we can observe how fast or by how much the liquid will rise inside the capillary. Then we can compare the results for the solutions to that of pure water. Thus, the method gives us a direct way to observe the effects of certain factors on the surface tension of water. METHODOLOGY: CAPILLARY RISE METHOD Calibration of the Capillary Tube Using De-ionized Water The inner diameter of the capillary tube was measured by performing the capillary rise method using de-ionized water. The tube was first cleansed with hot nitric acid, and was rinsed with water afterwards. Then, using a marker or pen, a zero mark was placed near one end of the tube. The capillary tube was then dipped into a test tube containing de-ionized water, until the zero mark coincided with the water level. The initial water level in the test tube was about an inch below the edge of the test tube. Upon immersion of the capillary tube into the test tube, the water level inside the capillary was elevated over that of the surrounding water. This height difference was then measured using a Vernier caliper. Five trials were made for this procedure, and the inner radius of the capillary tube was calculated using the formula: Measuring Surface Tension of Aqueous Solutions of Sodium Chloride and Acetic Acid The effect on surface tension of factors such as concentration and solute type was examined by performing the capillary rise procedure on 0. 5 M and 1. 0 M solutions each of sodium chloride (NaCl) and acetic acid (HOAc). Each solution was placed in a separate test tube, with the liquid level rising to about an inch below the edge of the test tube. The test tubes were immersed in a water bath to ensure that they had roughly the same temperature. The same procedure employed during calibration was used. The capillary tube was dipped in the test tube until the zero mark coincided with the liquid level. The height difference between this initial level and the elevated level inside the capillary was measured using a Vernier caliper. Five trials were performed on each sample. A more general form of [Eq. 1] above was used to relate the surface tension of each sample to the height difference, as well as to the inner radius of the capillary. Equation 2 above, together with [Eq. 1], was used to calculate the surface tension of each sample solution.
