Introduction Determination of bone mineral density helps in assessing bone quality. For instance, loss of bone mass which is obtained clinically as the change in BDM (bone mineral density) aids in determining bone fragility (Paschalis, 2009). Though, bone mineral density cannot be used alone to indicate that someone will suffer from bone fracture since there is the difference in BDM between the populations. Some people in a particular community develop bone fracture while others do not. Some…

Geographical and Cultural regions of Texas The Panhandle plains The Panhandle plain is situated in the northernmost of Texas State. This major Texan geographical feature spans about 81,500 square meters. The feature is narrow and straight forming the shape of a pan. The Panhandle is majorly covered in grassland, plain and some areas flat. In other cases, the Panhandle plains is referred to as the ‘Staked Plains’ or Llano Estacado. The Panhandle is majorly treeless. The land is situated in a…

Before the invention of modern antacids, people would chew chalk (calcium carbonate) to relieve the burning felt by too much acid in the stomach. But most currently used antacids are a combination of aluminum and magnesium hydroxide, often containing sodium bicarbonate as well. The antacids counteract stomach acid by neutralizing…

Unpolluted rainwater has a pH of 5.6 because to the carbon dioxide in the atmosphere (Acids…). However, this is the pH of the water as it falls. In the atmosphere, it has not come into contact with materials like carbonate or limestone, which are prevalent in freshwater (Kemker). Carbonate and limestone are buffers that increase the alkalinity of water (which means it’s more basic). Rain can get even more acidic than that, especially when pollutants like sulfur dioxide and nitrogen oxides come…

Biogeochemical cycles are the way in which nutrients move through the earths system. It is a pathway for chemical elements to move through biotic and abiotic factors. The ocean contributes largely to these cycles as it acts as a reservoir or sink for the accumulation of nutrients. Even water itself is recycled through precipitation, evaporation and condensation. This is a typical cycle that can be observed for the vital elements of life such as carbon and nitrogen. Microbes are essential to the…

When we burn things like gas, oil, or coal, the result of that turns into carbon dioxide where it is released into the atmosphere and it acts as a greenhouse gas. The thing is, greenhouse gases caused by human activity are not only affecting the environment but also that oceans all around the world. This of course partially has to do with the overall warming of the planet caused by climate change. But, over time most of this carbon dioxide in the atmosphere is being absorbed by the ocean, where…

These polyps get 90% of their energy from small algae called zooxanthellae which also produces their colour. Bleaching occurs when the polyps get rid of the zooxanthellae which leaves the clear polyps on top of a coral skeleton (a calcium carbonate skeleton which is built underneath most corals). Without the energy from the zooxanthellae the polyps begin to starve. The cause? The increase of sea temperature caused by global warming caused by excess carbon dioxide released into the atmosphere…

Reaction is 6CO2 + ATP → Glucose + 6H2O. In lab the class performed a couple of different experiments the one that is going to be observed is the effects of carbon dioxide concentration of photosynthesis. The group’s hypothesis was that the 6% sodium carbonate would give the highest reaction because the Elodea will give off more oxygen. The reason why we picked this hypothesis is because we believed that since there was a higher concentration of carbon dioxide it would be a Light Dependent…

This refres to a reaction in which there is not enough O2 in order to react with atom C in buthane to change into CO2 therefore they will change to carbon monoxide. The oxygen reacts with H to produce H2O these can be defined by incompelete combustion. Use Markovnikov's Rule to explain why Propan-2-ol is formed during the reaction between propene and steam. (A.C. 2.3) According to his role if a HX compound was added to an unsymmetrical alkene the H will bond to the compound. As propane is an…

Biology Field Study Draft Part A Bulimba Creek is a perennial stream located in the eastern and south-eastern areas of Brisbane (Committee, 2016). The creek covers an area of 122 square kilometres and runs through 20 of Brisbane’s southern and eastern suburbs as it makes its way towards the Brisbane River (Committee, 2016). As a result of the creek covering such a large area, Bulimba Creek is a very important part of Brisbane’s ecosystem and society. Although Bulimba Creek is a part of…
