Ecosystem Preservation versus Conservation Earth is composed of many different ecosystems and each one is a "dynamic complex of plant‚ animal‚ and micro-organism communities interacting with the non-living environment as a functional unit" (Protecting Threatened Ecosystems‚ 2004). These ecosystems are an intricate part of the human lifecycle as they provide us with our water‚ food and energy. Since mankind is in a take and take some more relationship with the ecosystems‚ many of them have had their

The Darkness Within: How Poe Portrayed Psychology within Literature Edgar Allen Poe was a master at exploring the psychology and fragility of human nature through poetry and short stories. A heavy contributor to dark romanticist fiction and psychological realism‚ much of Poe’s work focused on the psychological states of individuals‚ even though Psychology as a scientific study would not be introduced until several decades afterwards. Poe explored the fragile relationship held between the heart and

Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

Respiration‚ digestion and rocks Respiration Respiration is a chemical reaction that happens in all living cells. It is the way that energy is released from glucose‚ for our cells to use to keep us functioning. Remember that respiration is not the same as breathing (which is properly called ventilation). The glucose and oxygen react together in the cells to produce carbon dioxide and water. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Digestion

References | PAGE | 1.0 Introduction Respiration usually occurs in two ways‚ aerobically and anaerobically. Aerobic respiration uses oxygen to function and anaerobic respiration functions without oxygen. Generally‚ anaerobic respiration starts by breaking down the molecules of glucose and produces pyruvic acid. The pyruvic acid then undergoes fermentation to produce ATP‚ the basic energy source in our human body. Although this kind of respiration is less efficient in producing energy‚ because

Introduction Cell respiration is the process of a cell converting sugars into ATP (energy) in the mitochondrion. It is an essential process which enables organisms to survive and function (Biology Online‚ 2010). Not only does it produce ATP‚ but also carbon dioxide (though decarboxylation)‚ NADH and FADH and in the case of some organisms‚ alcohol. Saccharomyces cerevisia‚ a bacterium commonly known as yeast‚ is used in various aspects of life‚ from winemaking to baking. It respires both anaerobically

In the face of rising inflationary pressure in Hong Kong‚ some people have suggested that the Linked Exchange Rate system is the root cause of the situation and that the Hong Kong dollar should no longer be linked to the US dollar. The Financial Secretary already stated in his blog on 14 August that the Link continues to be the most appropriate exchange rate arrangement for Hong Kong. I will elaborate further on a few related issues. Many people who advocate un-pegging the Hong Kong dollar from
