drop by drop, to see how much hydrogen peroxide remained in the solution, which was our dependent variable. An enzyme is a catalyst, and it has two fundamental characteristics that it is known for. One of these things it that it can increase the rate of a chemical reaction without being changed or destroyed in the reaction. The second is that they don’t alter the chemical equilibrium between the reactants and the products while they speed up the reaction. In enzyme catalysis, the substrate,…

According to Huang, there are two local reasons behind this: the province has a disproportionally high smoking rate and the province’s industrial structure is heavily reliant on coal and non-ferrous metal industries. On the other hand, northern provinces such as Heilongjiang are known for high-fat and high-sodium diets and therefore experience higher levels of…

Over the generations, ancestors evolved different allele frequencies due to recurring natural selection. In fact, natural selection and mutation were considered the main hypotheses for the sickle gene cell. However, those hypotheses limit in explaining the entirety for the frequency of the HbS allele in human populations around the globe. The complex relationship between the HbS allele frequencies and the level of malaria prevalence support the malaria hypothesis at a global scale and further…

Description of the proposed heat release rate model. The cylinder gas is considered as a spatially homogeneous thermodynamic system occupying in a single zone for the compression, expansion, intake, exhaust processes and two zones (burned and unburned zone) for the combustion process. The instantaneous composition of cylinder gases are obtained from the mass fraction of fuel burned. The instantaneous thermodynamic properties are computed by the established equations [20-21, 28]. The…

The 1980s was also the time of the steepest declines in black dropout rates for young adults. However, while black dropout rates in the 1980s did significantly decline on their own there still remained a large gap between black and white students. Though college completion rates from the 1960s until the mid-1970s saw mild steady growth rates for African Americans. But there was decrease in rates in late 1970s, perhaps due to the greater incentive to gain employment after secondary school (Pew…

Markowitz Portfolio Theory One of the major area of finance is optimizing the portfolio. Basically, portfolio theory deals with the risk and value of portfolio instead of individual securities, which is known as Markowitz portfolio theory that is suggested by Harry Markowitz in his article “Portfolio selection” in the Journal of Finance. Markowitz portfolio theory basically helps in making optimum portfolio by interpreting, and evaluating risk and return of different risky assets. Basically, the…

“However, other age groups in the United States, including infants, have also been known to face higher death rates.” Stating a logical statistic about Americans was a pretty standard move, but Storrs hit the nail on the head when she added that piece of ethos in about infants. Can you imagine concerned parents reading the morning news to find this on their dashboard…

paper industries. With new frontiers in biotechnology, the spectrum of amylase application has expanded into many other fields such as clinical, medical and analytical chemistry. (Saranraj and Stella, 2013) As the temperature increases, so does the rate of reaction. A very high temperatures will denature enzymes. The enzyme activity gradually increases with temperature…

Figure: 1.2 above displays 13.48% students attained division I and II from 2007 to 2011. The pass rate dropped in 2011, where only 3.58% attained divisions one and two. The rest majority percentage of the students lagged behind with division three, four, and zero. The result was even worse in 2012 where more than 60% of students attained a Division Zero score. The devastating results as Hartwig, (2013) indicates gives no prediction of how the learning outcome would increase wellbeing and or…

It reminded me that even when we are young and growing, our internal clock is still ticking down from the very second your born. Although this may seem like a sad and depressed way to think about it is really not. Mortality is something that no one enjoys thinking about, and it is proven in different social cognition studies that contemplating our own mortality can threaten our Self-Esteem. But, apart of life is death and this should only make you strive for a good life. Aside from that, the…
