The tsetse fly is predominant found in large areas of sub-Saharan Africa where there is human settlement and agriculture. The tsetse flies are cousins of the house fly, however they are larger than a common house fly. Approximate length of a house fly is 6 to 7 mm while a tsetse fly ranges anywhere from 6 to 16 mm in length. There are approximately 22 different kinds or species of tsetse fly living on the continent of Africa presently. The scientific name for the tsetse fly is Glossina. Each of the
Introduction. Genetic engineering or genetic modification of corn refers to using molecular techniques or other similar techniques of biotechnology to add slight quantities of chromosomal material to the atomic structure and composition of corn, to protect it against infestation by pests, harm caused by herbicides or to increase its quality 4. In general, genetically modified corn is wired to resist herbicides and to produce its own insecticide. The trait in corn which tolerates herbicides is produced
tunneling pests would also be affected as a result of the direct delivery of the Bt toxins in the roots of the crops. The integration of Bt toxic genes into the plants’ genetic material would also prevent exposure of this insecticide towards non-target insects. The bacterium in which the genetic material is derived from produces certain toxins that prove to be toxic for several common agricultural pests. These toxins responsible for the insecticidal properties of the bacteria are vegetative insecticidal
Organic food has better ratings on health benefits than conventional food but conventional food costs less. Most people have a hard time making an educated decision on the better selection. Scientists and consumers have reviewed and theorized that the healthier option for the human body seems to be consuming organic food in comparison with traditional foods. Many people disagree about the legitimacy of the argument for organic food consumption, and whether it will result as the healthier choice.
Jurassic Park The girl shrieks as the giant tree trunk of a leg crashes down shaking the earth. Her screams are then drowned out by the prehistoric roar of the genetically engineered Tyrannosaurus Rex as it searches for prey (Crichton, 1991). Everyone remembers this scene from the best-selling novel by Michael Crichton, Jurassic Park. These scenes were then brought to life by producer/director Steven Spielberg in the immensely popular movie by the same name. Is this possible? As technological
Motifs in Creation Myths The motifs found in the creation myths are undoubtedly different from those found in any other type of myth. Contrary to popular belief, the purpose of the creation myths is much greater than a primitive attempt to explain the mysteries of creation. Behind each creation myth is a vast variety of symbolism along with a number of motives which are often shared between cultures, despite vast geographical differences. My intention here is not only to discuss the purpose
It is a literal creation of a tree through the techniques of biotechnology called gene splicing. This technique involves the use of genetically altered DNA in which it is inserted into the embryos of trees usually from a bacterium or virus. The genes will be extracted from a discrete organism, whose transfer could never happen naturally
My name is Eric Kohn, and I am applying to the Summer Research Experience for Undergraduates in Integrative Biology at UC Berkeley. As a child, my grandmother during her battle with lung cancer inspired an interest in medicine, and altruism. I debated between a career in healthcare and a career in science throughout high school, but my experience in organic chemistry solidified my choice to pursue research as a profession. Although I was drawn in by its biological significance, I became fascinated
For as long as humans have studied the idea of reproduction, they have typically considered the process to be between a male and a female, or in the case of asexual reproduction, between two gametes. However, scientific discoveries of parthenogenesis challenge this idea. Parthenogenesis is a process in which a viable embryo can be produced from two eggs without the presence of sperm. Although the artificial recreation of this process in humans and vertebrates has not been accomplished, scientists
First Aid and CPR In the medical field we have a variety of procedures that can be performed to help people and patients feel better or how to save a life. Some of the procedures that are performed can be done by professionally trained personnel, or by anyone. Two very important medical procedures that are very common are First Aid and Cardiopulmonary Resuscitation (CPR). Both First Aid and CPR are used on a daily basis and are used worldwide, even if used in a slightly different manner the basic

originated in New Guinea. This cane is only suited for tropical regions with favorable climate and soil. S. barberi probably originated in India. S. sinense occurs in portions of India, Indo-china, southern China and Taiwan. S. edule is thought to be a sterile form of S. robustum and is found only in New Guinea and nearby islands (Purseglove 1979). Cane sugar is currently grown primarily in tropical regions. The highest latitudes at which cane is grown is in Natal, Argentina and at the southern extremes
takes examples of inhumanity from past and existing totalitarian societies and shows the extremes that can be attained by the use of an all–embracing regime. Orwell accomplishes a sense of claustrophobia and inhumanity through a variety of literary techniques, his careful choice of language and by creating images in ones mind of this dull, intangible, sadistic world. Orwell creates this atmosphere of claustrophobia through overwhelming and unsettling depictions of the dystopian world he has created.
1 Brief history of sugar beet The first references to the family of plants known as “Beta” can be found in Greek literature around 420BC. They were described as garden plants; dark and light varieties are mentioned. Sugar beet was first grown 2000 years ago originally for its leaves, which were probably the spinach or swiss chard of their day. Beet gradually spread throughout France and Spain, often in monasteries but also by peasant farmers. By the fifteenth century beet was grown all over Europe
produces exact copies of the organism that contains the desirable trait. • Plants will reach maturity at a faster rate. • Tissue culture allows for the growth of a plant without the use of seeds or pollination. • Plants are grown under controlled and sterile conditions which reduce the risk of being exposed to pests, pathogens and diseases. • Tissue culture allows for the clonal propagation of plant (production of multiple copies of the same genotype). Marker assisted breeding (or marker aided selection)

The major contributions to maize development during the 20th century have been a technique for breeding hybrid corn and improvement of the frame for large scale, industrial production of hybrid seed, and genetic makeup improvements in the maize plant that add to its increased production, it is suitable that a system for breeding hybrid

The Differences between Natural Ecosystems and Agro-Ecosystems An ecosystem is by definition the processes and interactions of the biotic community (living organisms) and inorganic component (physical and chemical features) of a particular environment. In a natural setting a stable, or climax ecosystem represents a state of natural equilibrium, whereby all occupant species compete for resources, and energy and nutrient cycles are balanced. Human farmers effectively out-compete most natural
the pain that he/she would encounter. He asked Dr. Charles Jackson for nitrous oxide, but he was given ether and told it had the same properties. The dental operation was a pain free success. Morton started testing ether on his dog, his goldfish, insects and even himself. At one point he knocked out his dog for so long he thought he was dead. After finding using ether was successful he tried it on some of his patients with great success. He was then ready to demonstrate his findings in front of
Introduction There have been an increasing number of foodborne illnesses in this country and throughout the world in recent years. This has led to a heightened awareness of food safety. Food irradiation is being looked at as a potential solution to the problem. Food irradiation is the process of exposing food to ionizing radiation. Research shows that food irradiation can reduce or eliminate harmful pathogens and bacteria in our food, thus reducing, or even stopping the spread of foodborne illnesses
