Recombinant DNA is genetically engineered DNA that is formed by splicing fragments of DNA. Organismal cloning is the artificial creation of a new organism that is genetically identical to its counterpart. DNA cloning is a recombinant DNA technique where cDNAs and fragments of genomic DNA are inserted into a cloning vector and maintained during growth of the host cells. Vector is an agent that transfers genetic material into a cell or organism. Restriction enzymes are bacterial enzymes that find…

In modern day society, Tuberculosis is presumed to not be the devastating pathogen it once was. However, being a disease from mainly Mycobacterium bacteria, tuberculosis is the second most killing disease in the world from a single infectious agent despite being curable (McNamee, 2014). Evidently, a report in 2013 shows 9 million people who have developed TB, with 1.5 million of this population dying from it (McNamee, 2014). Despite great efforts to control the spread of TB, it is still has…

Born February 12th 1809 - Died April 19th 1882 The voyage of the Beagle (most important work): Started December 27th 1831 (lasted almost 5 years) Voyage around the world He found evidence to propose a revolutionary hypothesis about how life changes over time (evolutionThe smallest, lowest islands were hot and dry = no vegetation The higher Islands were very wet. More vegetation Was fascinated by tortoises and marine iguanas on Island…

Abstract: Fire can be seen as an intrusive, destructive force of nature and many can only see fire as a disadvantage phenomenon, but fire is an essential requirement for many ecosystems. This report looks at the consequences of fire on recovering forests of Australia. A survey was taken in 2011 at Anstey Hill in two different locations, one at the location where Ash Wednesday took place in 1983 and at another location where and uncontrolled fire took place in 1995. The survey looks at the…

The Deutsche Demokratische Republik or GDR originated in 1949, and even though it seemed to achieve some democratic goals and managed to offer people a reasonably comfortable living standard, the regime was in fact a dictatorship, in which the regime controlled every aspect of political, social, cultural and economic life. Forty years after being established, the system backfired, culminating in the collapse of the regime in 1989. Starting with an analysis of the factors that combined to bring…

Identifying context Research question How has the introduction of Nile perch affected the native species in Lake Victoria, Kenya? Environmental Issue Alien species are species that are introduced to a new environment and the introduction is mainly with the aim of increasing biodiversity in that specific environment although it sometimes can be for decorative purposes, pest control among others (Society, 2017). Some are intentionally introduced while other come into the new environment by…

Niche that the organism fills The ecological niche or niche of an organism is the place and role in nature. This encompasses what it does, who it feeds, what it feed on as well as what it pollinates. Considering the role that the Brenton Blue butterfly fills, we find that like other butterflies, it serves as a pollinator. In this case, the Brenton Blue is a pollinator for its food plant, Indigo (scientific name Indigofera erecta). When the butterfly lands on the plant to feast on the nectar…

*Metatherians are an ancient group which are very diverse in body form, and occupy an enormous range of ecological niches. *The closest relatives…

full of hunting, killing, manipulation, fearfulness and harsh living environments. Nevertheless, the species involved in these interconnected ecosystems of the oceans have found ways to survive in these environments by each fulfilling a specific niche. The niche of some of these species is oftentimes accompanied by another organism, however, these relationships are termed as a mechanism known as symbiosis and are incredibly important not only to the animals that make up the relationship, but…

diversity was greater in the golf course area and species abundance was greater in the lake area. It is common experience that more species of birds breed in a mixed wood than in a field of comparable size (cite on bird). This is true because of the niches and habits of the birds found within this area. Most of the birds had nest and food sources in this area. Since the golf course area has been established longer than the Winthrop lake area, it can be concluded that these birds have prior…
