Random sequence

1. What aspects of DNA’s structure contribute to the stability of the DNA molecule? The DNA’s double helix structure and the hydrogen bonding that bonds the bases contributes to the stability of the DNA molecule. 2. The DNA sequence is: 5’-ATTCGACC-3’. What will be the sequence of the complementary strand using this strand as the template? The complementary strand would be TAAGCTGG. 3. When the base composition of double-stranded DNA from a new species of bacteria was determined, 30 percent of…

Omega Centauri and Tarantula Nebula As opposed to the more short lived and less dense colonies of young stars that group up to create open clusters, globular clusters exist as far greater, spherical collections of aged stars that contain many low mass stars, sometimes numbering among the thousands. Globular clusters are more commonly found among a galaxy’s centre where the vast majority of stars are. It is thought that globular clusters arise from large gas clouds early in the creation of our…

I have been identified as a Dynamic Learner Sequence 25 (Use First) When I have to complete a task I like to know exactly what is expected of me. I don’t enjoy operating in a place where I am forced to make assumptions or draw my own conclusions about any task that’s been given. I feel like being organized with the steps I take to complete a task comes with the territory of desire specific instructions. Even when I have self-generated tasks I maintain a tasker log book of which I identify…

energy from nuclear fusion, as they convert Hydrogen to Helium. As these massive stars begin to die once they’ve worn out their hydrogen and are now very old stars, they turn into giants/supergiants (old, large stars), resting just above the main sequence stars. This is where the “F” and “G” stars are located. The hotter they are, the brighter they are demonstrating the Sun being a G star. Next, the core contracts as the outer layers expand. This is leading to the explosion of stars eventually…

Stage Four: Protostar By this stage of the stars evolution, 100,000 years after the process began, it can now be plotted on the Hertzsprung-Russell diagram, which is used to compare the many different stars. Although it is still not fully formed, we are able to determine the type of star it will become based on its luminosity and temperature. In the nucleus of the condensed cloud, which could now fit within the orbit of Mercury at less than 58,000,000 km wide, electrons and protons are ripped…

12.5 hours. The diameter is about 2.2 million miles, which is 2.5 times the Sun, the temperature is approximately 17,000 F (9,500C), the luminosity is about 40 times the Sun’s size, and the star type is is a white main sequence star, so it is in A class. Since it is a main sequence star, it fuses hydrogen into helium in its core, The Vega star is also known as the Alpha Lyrae and is in the Lyra constellation. It is a blur to white star and has a radius of 1.1 million miles, 2.5 times larger…

An astronomical star catalogue lists stars by number according to different criteria (such as their magnitude), which can provide insight into the positions of stars, how they change over time, and even the history and culture of the astronomers who create these catalogues. As early as the 2nd millennium B.C.E, star catalogues have been kept (Van der Waerden); they can be seen all over the world and across cultures, increasing in breadth over time as the technology of telescopes advanced and…

Quantitative risk analysis is the one which follows the Qualitative analysis, and gives a numerical priority rating to project risks (PMI, 2009). Based on the PMBOK (PMI, 2013) quantitative risk analysis “… is the process of numerically analyzing the effect of identified risks on overall project objectives (p. 333).” This is also a process for the PM and project team to get risk data to support making decisions, which can help to reduce project uncertainties (PMI, 2013, p. 333). Based on the…

aspect of evaluating credit derivatives, the copula function has gradually become the main approach in pricing CDO (Burtschell & George, 2005). In Li (2000) paper, a new random variable named ‘time-until-default’ was created to demonstrate survival time of each defaultable entity. And the copula function approach is based on this random variable to evaluate the default probability of financial instruments. Specifically, copula function specify the joint distribution of the survival times after…

precise, as the average weight difference is identical to that of the weight difference caused the glucose solution. Low levels of precision can be accounted for by random errors. Random errors are errors caused my unpredictable factors such as wind change or a mistake in the method. In this experiment, there are many possible sources of random errors that may have influenced the results and these may have…
