1. DNA in forensic science: DNA contains the genetic code of a person. The genetic information stored in the DNA, is coded in the form of nucleotide sequence. The nucleotide sequence is formed by four fundamental nucleotides: A, T, G, C nucleotide, that formed a polymer in a set order. A typical human DNA, has 3 billion nucleotide bases. The DNA sequence is 99.8% identical in all human beings and is only 0.2% dissimilar. This dissimilarity is the basis for identification of the suspects in forensic medicine. No two human beings can have a DNA that is 100% identical. ...

The correlation between climate and vegetation is evident in Africa, where, despite the rapid destruction of natural vegetation by humans and animals, there are still vast areas of natural vegetation. There are two main zones in Sub-Saharan Africa.

AREAS OF EQUATORIAL FOREST

The rainforests cover just under 1000 km in latitude and approximately 2250 km from west to east, from the Cameroon coast and Gabon to the eastern borders of Congo - Kinshasa (to the mountains flanking the Rift Valley to the Ruwenzori, the Virunga Mountains and Ugoma (northwest of Lake Tanganyika). The equatorial forest has a wide variety of trees (very high ...

Introduction

The growing shortages in food supplies, rapid climate change and increasing awareness of environment stewardship has all made eco farms an increasingly viable option. By reversing environmental deterioration, supporting local communities and balancing out community-ecosystem-market relations ("Solution: an eco-farming revolution," n.d.), eco farms are gradually replacing conventional forms of agricultural production, particularly as factory agri-products are becoming subject to mounting pressure not only from environmental groups but also from consumers growing more disillusioned by a combination of unhealthy products, price hikes and environmental damage. True, biotech industry appears to inform adoption of GM foods for international expansion and profit ...

The population of the world is expected to increase by almost two billion by 2050. This means that the world will have to prepare to feed two billion more mouths in the coming decades. The demand for food will not only increase by increasing population but also by increasing demand for the food in developing economies like India and China. As these economies are growing and the populations of these countries are becoming more and more affluent, it has led to a tremendous increase in the demand for meat and dairy products. All in all, it is believed that ...

The following is a layman’s version on the processes that produced the first intelligent, sentient creature, the human being. The paper will address the time through the forest- savannah transition in east Africa and through to the first hand axe and spear making, a period of approximately three million years ago. The paper will propose probable events that might have occurred during that time. The pre-human ancestors went from among the weakest and defenseless prey on the plains of African grassland to the voracious terror of the modern world, within an interval of approximately one million years. How did that ...

General description

Mali as a country started its fight against independence in the 1930s. Political opposition did not initially emanate from political parties rather they came from individual that had organized themselves into a number of voluntary organizations (Velton 13). These voluntary organizations compromised of cultural and sporting associations where most educated individual would meet under the French approval. Political parties were formed in the 1940s where the struggle for independence from the French continued. In June 20, 1960, Mali gained its independence from France. Mali covers an area of 478, 640 square miles. It has a population of about 11, 626,219 ...

1. ‘How does the rainfall of grasslands like this compare to deserts and forests?’ Grasslands are located between the forests and the deserts the distribution of rain is different in the three zones. Grasslands receive moderate rainfall ranging between 500 to 900 mm annually while forests receive high rainfall and deserts receive low rainfall. 2. ‘How does the behavior of communal (group) calving help the survival of Mongolian gazelles?’ Mongolian gazelles communal calving helps them to move together in groups hence are able to resist predators that locate them from afar considering the grasslands do not ...

Long-term Ecological Research

Introduction Long-Term Ecological Research or LTER network is the longest-lived and largest ecological network in the U.S. This network provides the research platforms, scientific expertise, and lasting datasets that are essential for analyzing and documenting environmental change. The network fuses a multi-disciplinary group of over two thousand graduate students and scientists. The twenty six LTER sites cover diverse ecosystems in the Pacific and Caribbean, which include deserts, lakes, estuaries, oceans, prairies, coral reefs, alpine and Arctic tundra, forests, urban regions, and manufacture of agriculture. In this essay, we will discuss the hypothesis and results of one of the LTER ...

IUCN (International Union for Conservation of Nature) describes that Utah Prairie Dog is a species of rodent that inhabits the grassland in the southern part of Utah in the United States. This species inhabit grassland areas and feed on grasses and forbs (USFWS 5) that are readily available in their habitat. Social structure of this species is called a clan consisting of an adult male, several females and their young (USFWS 5). Historically, the habitat of Utah Prairie Dogs were reportedly extended from Pine and Buckskin valleys in Beaver and Iron counties, north to Salina Canyon and near Gunnison in ...

Producers are the organisms that capture the Sun’s energy and convert this energy into a usable form of energy for themselves or others. Examples of producers in grassland include shrubs, trees, lichens, mosses and grass, etc. Consumers are the organisms having no way of capturing the Sun’s energy and rely on energy gained from producers or other consumers. Examples of consumers in grassland include elks, black bear, Western rattlesnake, red-tailed hawk, etc. Decomposers are the organisms that break the organic layer in the soil in order to provide nutrients to the producers. Examples of decomposers in grassland include ...

The North American Great Plains is home to diverse species of flora and fauna. It is well-known for its prairies, which are large areas of land that are dominated by grass, and could be broadly categorized into three: shortgrass, tallgrass, or mixed (Fick 189). This paper will focus on two species, one animal and one plant, that are found within the North American prairies—the black-tailed prairie dog and the stinging nettle plant. The black-tailed prairie dog (Cynomys ludovicianus) is one of five species of prairie dogs that exist in North America, and was the most common and ...

Is there anything we can or should do, to save the environment? Before we answer that question, it would be appropriate to understand why this question is raised in the first place. As the population grows, it has to be compensated by infrastructural development, which means that, more and more uninhibited land has to be utilized for housing and other social necessities. These could be the development of roads and drinking water, schools, colleges and hospitals, and industries to support employment opportunities. A number of developing countries have sold agricultural and barren land to multinationals to establish their manufacturing ...

The hydrological cycle refers to the continuous movement of water on, above and below the surface of the earth. It mainly involves the processes of evaporation, condensation, precipitation, infiltration, percolation, interception and runoff/overland flows. The main source of energy that drives the cycle is solar energy and therefore the main changes in energy involve changes in temperature. When surface water is heated, it gains energy and changes from liquid state to gaseous state. This results in a cooling effect to the surrounding region (Arctic Climatology and Meteorology) Transpiration also contributes in adding water vapor in the atmosphere; this is referred ...

In a given ecological setting, some species dominate and influence the abundance of the other species in that ecology. Two pathways, which lead to dominance, exist: competition where the dominance species has superior access to the limited resources and low susceptibility to other processes that are not competitive. In the second pathway, the non-dominant species are normally very susceptible to the non-competitive processes. The former pathway is highly interactive and the dominant species suppresses its subordinates by limiting the resources available to them. Sustained dominance reduces the diversity of species that ecology. The second pathway is weakly interactive and the ...

According to (Whitefield 15), reading landscapes can be quite complex. This is because a landscape consists of several components, which change with geographical surroundings. As a consequence, different geographical areas have dissimilar landscapes. Although the landscape mainly describes as the geographical or physical features of an area, it also includes the living things which inhabit that location. In a literal sense, this means that animals and plants are also part of the landscape. To a great extent, landscape affects the culture, values and behavior of people in an area. The rooflines of an area can be used as a prologue for reading the ...
