Introduction- IVTC as a Technique It has taken decades to develop the in vivo cryotechnique (IVCT), which is currently being used for examination of the functioning of morphology in the living animals and other organisms. Using IVTC the animals and organisms are cryofixed while the blood is still circulating, this way all the soluble components in the body fluids and structural features of the organism in vivo are easily captured in the frozen tissue specimen. The morphological data from the experiment...

Global health ethics and is an elaboration of how scientist especially biologists contribute to the integrity of science in the public. A biologist is a scientist devoted to and producing results in biological fields through the study of life. They study organisms and their relationships to their environment. They majorly involve themselves in basic research and they try to invent underling theories that control how organisms work. Most a time, a biologist tries to develop and improve medical, agricultural...

The most common and the most popular butterfly species which can be found in almost all parts of the world is the Painted Lady butterfly. Its colorful appearance fits its name because of the dots of colors on its wings. An adult wear orange and brown on the upper side of its wings. Its forewing has black on its leading edge with white bar and smaller white spots. Shades of brown and gray mark the underside of its wings and while at rest, four small eyespots can be seen on the hindwing. Painted...

The consequences of extinction of Pleistocene megafauna symbolize the origin of plant growth and reproduction traits which have significant implications for interpretations of conservation measures in the contemporary world. The deficiency of dietary data for mega-herbivore species hinders scientific verification of these issues. New Zealand is forms the favorable ecosystem for effective ecological reconstruction. The terrestrial ecosystem in New Zealand was free of mammal species except for the...

(How Diabetes Mellitus is metabolically similar to Starvation) Diabetes Mellitus is a sugar or glucose related disease in the sense that blood sugar levels (glucose) are abnormally high because the body does not produce enough insulin to maintain and regulate glucose level in the blood. During the regulation and monitoring of blood glucose level, when levels of blood sugar rise because of the body digesting a certain mealmeals i.e. fed state cells in the pancreas release an hormone called insulin...

Abstract The influence of Drosophila melanogaster on the understanding of basic genetic concepts is examined. Crosses were performed between different species of both wild type and mutant flies. The results of both the first filial generation (F1) and the second filial generation (F2) are presented with the use of Punnett squares. Basic genetic concepts such as autosomal dominance, autosomal recessive, sex-linked dominant and sex-linked recessive characteristics were illustrated. Introduction Gregor...

As indicated by Morrow and Gradishar (2002), breast cancer affects women in the ratio of one to eight in their lives that is approximately 12 of all women. It is the second major cause of cancer deaths among women in the world exceeded only by cancer of the lungs. The chance that the death of a woman will result from breast cancer is about 3. Though one cannot clearly tell why some women get breast cancer there are some risk factors associated with its development. Age, genetics and personal factors,...

All biological activities are mediated by enzyme activities. Enzymes are specific to their substrates and function at the optimum levels under different conditions of temperature, pH, and many times also in the presence of specific coenzymes, cofactors and a metal ion. The metal ion is converted to oxidized andor reduced state by the change of electron(s) during a biochemical reaction. In the present experiment Pyruvate the end product was estimated in the presence its substrate and as effected...

Evolution of Genetics During the nineteenth century may philosopherresearches forced their imaginations to conceptualize the variability in all organisms. Charles Darwin was the frontrunner and based on his extensive travels and studying all kinds of life forms, even fossils of plants and animals. The Variation of Animals and Plants under Domestication The8 Variat ion of Animals and Plants under Domestication (1868) proposed a hypothetical mechanism of heredity as a provisional hypothesis called...

Summary of the article The research article entitled, Effects of soil salt levels on the growth and water use efficiency of Atriplex canescens (Chenopodiaceae) varieties in drying soil, authored by Glenn and Brown (1998) described the performance of three plant varieties to varying degrees of salt and water concentrations.  It has long been established that maximal growth and development of any plant species are mainly dependent on optimal environmental conditions.  These include an ample...
