Despite the fact that the content of a particular presentation is of basic significance, the mode of presentation affects the general reception by the audience and can promote of hinder the impact of the information that is presented. Factors that make a presentation wonderful and interesting include the scientific content of the information, format of presentation and the manner in which a person interacts and communicates with the audience. A professional presentation should be meticulously planned...

For scientists, evolution is the reason different kinds of species live on Earth. This evolution gave birth to diversity of organisms comprising a given population. One of the key concepts of this theory is natural selection. In layman s term, it is the survival of the fittest. The environment in which an organism lives will favor species that have characteristics that will ensure better birth rate. A classic example of this is the industrial melanism that happened in England during the industrial...

Cloning is one of the aspects of society that has been very much talked about and has been controversial. In the previous years, fiction literature featured how authors imagine cloned beings would become part of the natural order and system of the human life. In movies the topic of cloning has been greatly explored. This contributes to the generation of a growing interest on the topic. In the field of scientific study, cloning has already been existent for years now. It has created several different...

The name of this condition refers to the work of two doctors at the turn of the 20th century. It can vary from the mild to a life threatening effect depending upon the type as the title now covers 6 related closely conditions. Despite the years that have passed since it was discovered and given its name no cure has yet been discovered. It is sometimes referred to as cutis hyperelastica. It is one of a group of connective tissue disorders, all of which are genetically inherited, and which are caused...

During the 1960s, America was going through many changes.  Schools were being desegregated, the Civil Rights movement was in full force, and police investigating was about to take a whole new path for finding justice.  The field of forensic science was on the brink of making its mark in the justice system. Unfortunately, its use in law enforcement did not occur until many years later.  In the 1994 book, The Chamber, written by John Grisham the field of forensic science is brought...

Chilling damage is a physiological defect in higher flora brought about by contact to low temperatures just above freezing point. Some crops of commercial importance are affected by temperatures below 150 Celsius. This is known as chilling injury. Crops affected include sweet potatoes, sugar cane, sorghum, potatoes and maize among others. Indications of such injury consists of partial growth of photosynthetic material, pitting of the outer layer of plant, staining and uncharacteristic ripening of...

Cystic fibrosis is a genetic disease that primarily affects the lungs however, it also affects the gastrointestinal tract and pancreas.  Salt is not properly transported away from the cells, which causes the lungs, intestines, and other organs to break down.  As a result, mucus builds us and blocks the airways it traps bacteria and causes infection. It affects about 30,000 young people in the United States, predominantly white children. The disease is very rare in Asians.  Only five...

Critical thermal mass is measured by the temperature at which a given species may become unorganized in locomotion and that which will subject the animal to death. This is particularly true if the species has limited mobility and lacks the ability to seek a microhabitat of reduced thermal stress. Fish are often used to determine thermal tolerance because when they are in a temperature just slightly below critical thermal mass, they float belly up, so this temperature can be measured without killing...

The human body is able to surviveagainst the potential pathogens like bacteria and virus because of its immune system developed. Human body produces antibodies to immobilize pathogens for removal from the body when they able to multiply above a level of equilibrium situation. This immune system can be disturbed by chemical toxins in the system. Bacteria or Virus which is difficult to control   Mostly the human illness was caused by viruses and bacteria on earth. Bacteria are small single celled...

Lactobacillus is normally found in fresh meat and occurs naturally. The application of this microorganism is wide. Its biotechnological potential defines its application in production of fermented meat. Some of the genes find importance in food processing. This is achieved through change in oxygen and redox levels. The surfaces of meat have been found to be colonized by some organism by forming biofilm. Lactobacillus is found in some parts of the human body. These include the intestines, mouths,...
