Introduction

Placids can be defined as the endosymbiotic organelles, which substantially rely on the cell of their hosts to survive. Even so, placids are reported to have shown so much diversity in different situations. Therefore, ways through which differences emerge has been addressed. Some of the aspects that contribute to these differences are such as the difference in the lineages from which plastids originated. This is evident given that there are primary and secondary lineages from which the plastids can stem from. Additionally, the cause for the small size of the plastids has been established. Plastids are ...

Impact of climatic change on the Great Barrier Reef

Climatic changes refer to lasting and significant changes in the weather patterns characterized by statistical distribution over a period spanning decades or hundred thousands of years. These changes may encompass extreme weather conditions and may happen due to variations in solar radiation reaching earth, biotic processes, volcanic eruptions, melting of the polar caps and plate tectonics. Certain activities undertaken by humans have also been recognized as contributing to negative climatic changes such as global warming. This climate change has threatened earth's ecosystems. The recent harsh change in the climate such as an increase in temperature takes a great toll on the ...

Charles Darwin published his masterpiece detailing his theory of evolution by natural selection, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life in 1859. Despite the overwhelming consensus of the scientific community, there are still loud and politically active Creationists that insist that the earth is less than 10,000 years old because the Bible says so. However, the Bible never actually states how old the universe or the earth is. Belief that there is a Creator and in the theory of evolution are compatible for followers of ...

Abstract

Cars have always played an important role in the course of human development. In the past, man had a vision to introduce an invention to transport people along long distances. To turn the vision of a self-propelling automobile into reality, it took the development of a reliable combustion engine that operated on liquid fuel. In 1672, the first steam-powered vehicle as a toy for the Chinese emperor was built by Ferdinand Verbiest, a member of a Jesuit mission in China. As the automobile industry grew, so did the rate of environmental pollution. Car engines are considered to be the prime source of air pollution. The ...

They hazardous human activities are evident in the most developed nation in the planet, whereby the industrial refuse are deposited to water bodies. With the above background in mind, marine or water ...

Asepsis

Microorganisms are the tiny microscopic structures that cannot be seen with naked eyes. They are present on all the living things and also in the environment. Some of these microorganisms are non pathogenic that is they do not cause any disease. However, many of the microorganisms are pathogenic in nature. The pathogenic microorganisms can cause disease or infections. Absence of these pathogenic microorganisms is known as asepsis.

Importance of asepsis

Asepsis is usually carried out in the laboratory mostly while dealing with microorganisms. The techniques used to carry out asepsis are known as aseptic techniques. If aseptic conditions are not maintained in ...

- The Causes of Global Warming Global Warming has always been an issue of debate, with environmentalists vehemently raising their voice against it. The main reason cited for global warming by researchers is the emission of greenhouse gases largely because of ever-increasing population and related changes in standard of living (Derek Markham, 2009). The main greenhouse gases causing this effect are carbon dioxide, Chlorofluorocarbons (CFCs) and methane (WMO, 2011). These are caused mainly by burning of fossil fuels such as coal, oil and natural gases for generation of electricity, running vehicles, warming and other industrial processes. - ...

Introduction

Marine pollution takes place when potentially harmful or harmful particles, chemicals, waste, or invasive organisms get into the ocean. Most sources of marine pollution are based on the land. Marine pollution usually comes from nonpoint sources dust, windblown debris, and agricultural runoff. Marine pollution can also result from nutrient pollution where excess nutrients is put into the sea. The result of this excess nutrient such as phosphorus and nitrogen stimulate the growth of algae which cause eutrophication on the surface of the sea (Birni & Boyle, 1994). Marine pollution causes presence of toxic particles into the sea. These toxic particles ...

Tropical coral reefs are deep-sea habitat made of calcium carbonate. Corals secrete the calcium carbonate making most of the coral reefs. They occur in warm tropical waters with bountiful sunlight necessary for their survival. Coral reefs are made up of tiny marine creatures made up of few nutrients. Stony corals consisting of polyps make the basis for most of the coral reefs. Polyps belong to group cnidarians in the animal kingdom. This group of animals also consist the jellyfish and anemones. Different from the sea anemones, coral polyps secrete a hard exoskeleton made up of carbonate offering mechanical support to ...

Yeast fungus, more commonly known simply as “yeast” is a member of a larger family of eukaryotic organisms that includes microorganisms like molds and mushrooms. Scientifically this type of group of life forms is known as a kingdom. The broad group of the Fungi Kingdom includes multicellular organisms in addition to the simple single-celled yeast organism. Members of this kingdom are neither plant nor animal. They can be distinguished from plants by their inability to create their own food through the photosynthesis process. . Although some of the more complex members of this kingdom may have a plantlike appearance they lack the green ...

Historians link the origin of food waste with the urbanization which emerged due to industrial revolution. Crowding within industrial towns was characterized with indiscriminate disposal of organic wastes and recurring epidemics of communicable diseases. Food wastes if not properly managed, is bad to the economy and environment, and is the second largest generator of the waste stream within American landfills. After food waste is sent to landfills, they emit green house gases like methane and carbon dioxide which have adverse impacts or effects on climate change. Moreover, resources like water, energy, fossil fuels, and land used for generating wasted ...

The Research

The first source examined was the U.S. Department of Energy’s Alternative Fuels Data Center. Their published article “Biodiesel Benefits and Considerations” (Jan 2013) defines biodiesel as “a domestically produced, clean-burning, renewable substitute for petroleum diesel.” According to the article, a vehicle fuelled by biodiesel “increases energy security, improves public health and the environment, and provides safety benefits.” ...

Eutrophication refers to the development of algal in water bodies due to an increase in nutrients in the environment, which flow to the rivers and lakes. The growth of algal is contributed to by the availability of nitrogen and phosphorus nutrients (Goel, 2006). The main contributor to Eutrophication as a form of water pollution is the increase in nitrogen and phosphorus in the atmosphere. Eutrophication is a process that occurs regularly, but due to human activities, more nutrients are generated hence increasing the growth rate of algae in lakes. Population growth, which has lead to food scarcity, has prompted human ...

Chloroplast and mitochondria are membrane bound organelles found in eukaryotic cells’ cytoplasm. Chloroplasts are present in all multicellular plants and some algae species while mitochondria are found in most eukaryotic cells. Their main similarity is that both of these organelles generate the universal cell energy carrier known as ATP (Adenosine Triphosphate). - Chloroplast DNA Geneticists have long established that many chloroplast associated traits display cytoplasmic inheritance. This suggests that nuclear genes are not responsible for encoding of these traits. In 1963, it was discovered that chloroplasts have their own deoxyribonucleic acid (DNA) known as chloroplast DNA (cpDNA). ...

Some areas have become barren, while a few remained arable but in the risk of being converted into commercial lands for homes or businesses. In the United States, the problem of pollution not only affected its once diverse ecosystem, which is considered the home of ...

Abstract

Global sea levels have fluctuated during the earth’s long history, falling during the ice ages and rising during periods of global warming. The most recent ice age occurred more than 10,000 years ago. Over the last few decades, we have experienced global warming, which has been aggravated by the effects of global warming resulting into excess gases that trap heat in the atmosphere. Records on rise in sea level for the last 100 years indicate an average rise of one to two inches every 25 years and the figure is increasing. The rising sea level will have ...

Introduction.

Atmospheric pollution can be described as the process to which chemicals, biological material or particulate matter, that are harmful to humans and other living organisms, are introduced into the atmosphere (Jacobson, 2002). Man is considered as the prime polluter of the earth’s atmosphere from his daily activities that involve release of hazardous gas into the atmosphere (Cheremisinoff, 2002). The Environmental Protection Agency (EPA) considers the following six pollutants as principle contributors to atmospheric pollution: Carbon Monoxide, Lead, Sulfur Oxides, Ozone, Nitrogen Dioxide, and Particulate Matter like Sulfates, Nitrates and carbon based molecules (Vallero, 2008).

Introduction

Biomass is a biological material obtained from a living organism or a recently living organism. The word biomass is derived from two Greek words; bio meaning life, and maza meaning mass (Demirbas, “Fuels from Biomass” 43). Biomass means non-fossil and bio-decomposable organic matter (originating from plants, animals and microorganisms). The products, byproducts, residues and waste from agricultural processing, all constitute biomass. Bio-waste simply means non-fossil and biodegradable waste that is composed of organic matter. Bio-wastes include food and kitchen wastes, garden and park wastes, and wastes from food processing plants. Bio-waste is therefore an element of biomass. Non-fossil wastes that are ...

A biofuel is made from a biological process known as carbon fixation. These biofuels are gotten from the conversion of biomass, solid biomass, liquid fuels as well as biogases. The biofuels are continued to be known because of the high prices of fossil fuels and also for the purposes of ensuring fuel security in various countries. (Caye, D. & Terry W.2008). The biofuels are produced from two distinct ways; that is through metabolic by-products or from living organisms. Examples of biofuels include; bioethanol which is an alcohol made from fermentation process. Another example of biofuels is biodiesel which is made from ...

Abstract

Water is an important chemical owing to its various uses by living things. Most chemical reactions within the bodied of living things require water in order to occur. It is purported that life evolved from water some 3.8 billion year ago following the organization of inorganic and organic molecule to form as prokaryotic cells. Besides, the well being of a cell is overly dependent of the balance between the water and the dissolved substances in the water. In this regards, the cell can permit water molecules to move in and out of the cell; the process in called Osmosis.

Abstract

The subject of evolution is one that finds substantial amount of conflict from various fronts. Much of this conflict comes from theological stance where the story of creation is consistently quoted as the viable source that defines the origin of living and non-living things. However, the creation story lacks tangible evidence as compared to the story of the evolution. There is an overwhelming body of research works and evidence that clarify this. However, despite all the evidences provided, there exists some confusion as to the origin of the earth. A quick look at various academic books used especially in ...

Coral bleaching occurs when there is physiological stress experienced by the coral reefs. The stress is caused by an imbalance of the symbiotic relationship that the corals have with the algae that live within them. These algae are of the genus Symbiodinium. The algae are important to the coral reef since they are a source of nutrition and color. The algae will reduce or all will leave the coral reefs when there are harsh physical conditions. When this occurs, there is no tissue growth and sexual production in the corals. They end up losing color and thus the term coral ...

The transition from aquatic to terrestrial habitat no doubt posed some challenges to plants. They have had to overcome challenges in order to adapt completely to life on land. Some of the challenges that that plants faced by moving from water to land was the problem of water loss. They also had to overcome the challenge of reproduction. Also, terrestrial plants have had to evolve new ways of feeding. Some of these are presented below. The evolution of plants to terrestrial habitat took place from their ancestors which were algae. Algae had to adapt to living in shallow ...

Coral Bleaching: Causes, Effects and Response Action Plan Coral bleaching occurs when there is physiological stress which leads to an imbalance of the symbiotic relationship that the corals have with the algae that live in the coral leaves (Rosenberg, Kushmaro, Kramarsky-Winter, Banin and Yossi 1).

There are numerous descriptions of drowning that are available and actually, all of them bear some weight. According to Lunette, G., et.al death by drowning is the consequence of a obstruction of respiration by impediment of mouth and nose by a liquid medium which is more often than not water (2004). Actually, there are many other drowning definitions wherein all have some accuracy. In regards to true drowning, there are relatively no considerable disagreements, since there is a general conduit, which involves the water inhalation, which could eventually pass through the alveolo-capillary membrane thus eventually reaching the general circulation ultimately. Characteristically, a difference ...
