Printable organs concepts

The topic of 3-D printable organs very evidently, is starting to receive an increasing amount of attention. The whole mechanism of creating live tissue and organizing cells to form organs seems impossible and amazing. Until recent time, scientists had problems to keep cells in balance and preserve their survival, as there were few issues. Presently, […]

Phyletic Gradualism and Punctuated Equilibrium Evolution Theory

Evolution is the process by which generations of species undergo some changes in their biological traits over a given period. There are two theories that explain the process of evolution. They include phyletic gradualism and punctuated equilibrium. Scientists maintain that evolution can only happen as described by the theories (National Academy of Sciences 78). Phyletic […]

A Study of “Escherichia Coli”

Bacteria present a world that is constantly under study in the search for better understanding of life and its processes. The cells are being examined in “microfluidic devices” that allow for movement and create an environment to observe the interaction between cells, as well as internal mechanisms and reactions (Mosier & Cady 1). The division […]

Cell Membranes

The cell membrane is a biological layer that acts as a barrier between a cell’s interior and its exterior environment. Cell membranes act in a selectively permeable manner. This means cell membranes have the ability to control the entry and exit of substances in and out of their interior structure. Some organic ions and molecules […]

Possible Benefits of New Genetics

Introduction There is a lot of controversy attached to the idea of human cloning. For some people, human cloning is ‘ethically wrong’ and for others, it is a ‘repugnant’ and’ morally despicable’ practice. There are various potential benefits attributed to cloning. Emerging testimonies on human cloning have elicited mixed feelings on whether its potential benefits […]

The factors contributing to similarities and differences found in the species composition between two IKMT’s

Introduction Four series of oblique tows were taken with a midwater trawl in the San Pedro and Santa Catalina Basins off Southern California. Comparisons of biomass, numbers, and mean sizes of fish and decapod crustaceans between day and night tows show few significant differences, indicating that daytime net avoidance is not a problem with this […]

Human Responses to Features of Insects and Impact on Media on Image Representation

The fact that most people express their negative attitudes to some insects is culturally and historically predetermined. Most of the fears that people experience are associated with insects and the consequences of dealing with these creatures. However, these biases are premised on the images and experiences of previous cases of encountering insects. In fact, many […]

Safety of Birds in Confinement

Introduction Despite the fact that the appearance of natural structures change, reality will always remains (Honour & Fleming, 2005). In order to create pure reality, it is imperative to reduce natural forms to constant elements of form. Birds, when properly taken care of, will seldom be attacked with any disease. A good practice, therefore, is […]

History Of Biotechnology

Introduction Biotechnology can be defined as a technology that utilizes “biological phenomena for copying and manufacturing various useful substances” (Smith 3). Biotechnology was initially an artisan ability and not a science. This technology involved producing beer, cheese and bread among other related products, where processes were carried out in an accurate manner. These processes were […]

Pets and people

Introduction Love can be considered to be a strong emotional attachment between individuals or animals. It entails displaying attributes such as selfless loyalty, compassion, kindness and affection to others. This is a condition experienced by human beings and animals. Over the years, there have been questions as to whether animals are capable to love. There […]

The Melanin Theory

Melanin theorists purport that black people are more superior to the whites (Cashmore and Jennings 181) because they have greater quantities of melanin. They attribute whites’ alleged “inhumanity” and “inferiority” to lack of melanin. Melanin theorists also maintain that melanin bestows upon people of color some superhuman abilities. The theorists are unanimous that melanin is […]

Vertical Stratification

Stratification is an ecological term referred to various parts of a system that can be broken down into several layers (Hutchinson & Skelly, 2010). In community context, stratification refers to the manner in which life forms are arranged in a vertical array. Ecologists have identified light as a major factor that determines this vertical structure […]

In the prehistoric times, man relied on natural plants to satisfy his basic needs such as food, clothing, and shelter. Prior to the development of agriculture and domestication of plants, the hunter-gatherers derived their livelihoods directly from wild […]

Darwin on the origin of species

Evolution by natural selection is considered the backbone of biology. It is proposed that modern students should have time to read the literature of naturalists regarding their perception of evolution. This is endorsed by Charles Darwin and Alfred Lussel Wallice. Darwin commenced his superb creativity in evolution by natural selection with the initiative of divergence. […]

Evidence for ancient endosymbiosis

Research question and hypothesis Endosymbioses have remarkably changed the eukaryotic life processes, while it has impacted negligibly on prokaryotic evolution.
