subgroups. The most important of these are the A1 and A2 subgroups, which differ in the activity of their transferase enzyme gene products. The transferase activity in A2 individuals is less efficient in catalyzing the formation of the A antigen from the H antigen compared with those in the A1 subgroup, resulting in lower expression of A antigen. Type A2 individuals have relatively fewer Type I, Type III and Type IV carrier chains than Type A1 individuals. The difference in carbohydrate sequence…

Hello Disha, Thank you for the concise discussion of the disadvantages of the various techniques that are used in assessing the depth of the burn wound. “Burn wounds that heal within a 3-week window have improved aesthetic and functional outcomes with a reduced degree of scarring” (Khatib, Jabir, O’Connor, & Philip, 2014, p. 1). To promote optimal treatment for burn wounds, an immediate and accurate depth assessment is required (Sainsbury, 2008). Burn depth is frequently evaluated by clinical…

[Meier, D., Emmons, C. A., Wallenstein, S., Quill, T., Morrison, R. S., & Cassel, C. K., 1998]. The reasons patients ask for physicians to take part in ending their life are usually if they are in extreme pain, are a burden upon family members or caregivers, or have no personal dignity left. To choose relief is not only in favor of the terminal patients, but according to polls, the rest of the public is in favor of legalizing euthanasia as well [Meier, D., Emmons, C. A., Wallenstein, S., Quill,…

Three symbols used in the Scarlet Letter are the scarlet letter, Pearl, and the scaffold and all of these symbols are used differently by the Puritans and by the author. The meaning of the scarlet letter in the novel is for Hester to wear it because she has committed adultery. It is supposed to attract attention…

The first source that I found would be helpful for the research because it talks about planarian. The article talks about their regeneration. They focus about the cells, epidermis, and s phase of their body. It has a clear explanation of how they regenerate and produce new head or tail. Also, talks about their reproduction asexually. This will have clear explanation on why the flatworm from the lab multiplied. The second source would be helpful for the research because it shows all the steps on…

but the most common learning disability is dyslexia (Hallahan, D., Kauffman, J., & Pullen, P. (2015)). Dyslexia involves someone who has reading and writing disabilities (Hallahan, D., Kauffman, J., & Pullen, P. (2015)). Someone who has dyslexia might suffer from other learning disabilities as well (Hallahan, D., Kauffman, J., & Pullen, P. (2015)). Dyslexia has a wide area of issues within the learning disability spectrum (Hallahan, D., Kauffman, J., & Pullen, P. (2015)). There are multiple…

1.10. Uses of Lactic acid Lactic acid and some of its derivatives (salts and esters) are used in three main applications: foods, polymers, and industrial. Figure 2: Uses of lactic acid [22] 1.10.1. Food The food industry is the traditional large consumer of lactic acid and lactate salts. It is mainly used as an acidulant and preservative. Lactic acid has a mild acid taste and does not overpower weaker aromatic flavors. Since it occurs naturally, it does not introduce a foreign element into…

Many people had decided to move into cites to more easily surround themselves with these technologies and to find jobs in…

sulfur, conversion of sulfur to sulfur dioxide, conversion or sulfur dioxide to sulfur trioxide, conversion of sulfur trioxide to sulfuric acid. First, sulfur is obtained from mines. Once extracted, it is then burned in air to produce sulfur dioxide, S(s) + O2(g) → SO2(g). Next, the sulfur dioxide is heated and subjected to high pressure to produce sulfur trioxide, 2SO2(g) + O2(g) → SO3(g). This is due to the fact that sulfur trioxide’s equilibrium yield increases when temperatures are low,…
