... hard to believe. It gives good reason to the expansion of the universe, and the 360degree view of the universe (this because the explosion would have sent mass outward in every direction), but I wouldn’t think of it as the origin of the universe. I mean, in my mind, something had to be there to cause this super mass. Was the universe contracting until it formed this huge mass? I believe that we may never know how the universe came about, rather have some idea as to what came directly before it’s current state as well as before that and so on. We could come up with ideas until we die, and someone would just continue in our footsteps. I do have one idea as to how this ...

... of fats and oils. It is essentially the reverse of esterification. O O R-C-O-R’ + NaOH ---- R-C-O-Na+ + R’OH Ester(fat) + base(caustic soda) ---- salt of fatty acid(soap) + alcohol(glycerol). Caustic potash (potassium hydroxide) can be used instead of caustic soda (sodium hydroxide)but is more expensive. The base used to come from wood ash containing potassium carbonate which formed potash as this was not plentiful it made soap a luxury. The cheapest source of the ester is animal and vegetable fats and oils. H-H-H-H-H-H-H-H-H-H-H-H-H-H-H ...

... results from partial deletion of the factor VIII gene, and is severe. Other cases result from a single base mutation in the gene. This can result in nonsense mutations which result in premature stop codons, and a severe expression of the disorder, or missense mutations which cause milder forms of the disorder. In some cases the disorder can also result from spontaneous mutations, but this is less common. The gene for hemophilia-A is located at Xq28 while the gene for hemophilia-B is located at Xq27.1-q27.2. There are about thirty other disorders associated with the Xq28 area including manic depression and favism. This must indicate that Xq28 includes many dif ...

... profit. More specifically, premiums less costs provide the all important profit margin, the life blood of the insurance industry. By not providing coverage for the billion dollar industry of alternative treatments, insurance companies are keeping the cost of the premiums down but at the same time not allowing their customers to use complementary treatments such as chiropractic to prevent or cure illness. The more rigid and restrictive the policy provisos, the more assurance for the companies that they will maximize their bottom lines. Therefore, patients of alternative therapies as well as doctors must show that such unconventional treatment provides r ...

... have unpleasant or painful experiences they would rather forget, nor is it claiming that children often experience both wonderful and brutal things for which they have no conceptual or linguistic framework and hence are incapable of understanding them, much less relating it to others. It is questionable because this model maintains that because (a) one is having problems of functioning as a healthy human being and (b) one remembers being abused as a child that therefore (A) one was abused as a child and (B) the childhood abuse is the cause of one's adulthood problems. There is no evidence that supports the claim that we remember everything th ...

... Solutes are usually solid substances, and they are not limited to only being solids, for example another liquid can be the solute. Some liquids can dissolve in each other in any proportion; others have limits. If a solute added to a solution above a certain amount will not dissolve, the solution is called saturated. For most substances, solubility increases with increasing temperature of the solvent. In general, molecules that are structurally similar to the molecules of the solvent have the highest solubility. When a solute is added to a solvent, several physical properties of the solvent change. Its boiling point rises and its freezing point lowers with i ...

... followed by low mood or depression. The number of manic and depressive episodes varies greatly from person to person and most individuals experience "normal" periods between their manic and depressive episodes. Manic depression can send a person plunging from a high state, where one may believe one has superhuman energy and abilities, into a pit of despair, where it may seem as if the only way out is suicide. There are two types of bipolar, bipolar 1 and bipolar 2. Bipolar 1 is diagnosed differently than bipolar 2. Bipolar I is diagnosed when person has a manic episode and has had no depressive episodes in the past. However, after the first manic episode occ ...

... is the site where the synthesis of a new complementary strand will be formed. Because of the DNA “unzipping”, there will be two single strands of DNA. Hence, because there is two single strands of DNA, there will be two new daughter strands synthesized. However, each of these daughter cells is synthesized in different ways. The first strand of DNA is built by simply adding nucleotides to its end. This strand grows inward towards the replication fork as the DNA molecule unzips. This strand ends with a hydroxide (OH) group and is called the 3` prime or 3`end. The enzyme that catalyzes this process is called DNA polymerase. The second strand is built by having a ...



Determining The Ratio Of Circumference To Diameter Of A Circle

... the circumference of the circle by the diameter I was able to calculate the experimental ratio, and I knew that the accepted ratio was pi. Then I put both ratios in the chart. By subtracting the accepted ratio from the experimental you find the error. Error is the deviation of the experimental ratio from the accepted ratio. After I had the error I could go on to find the percentage error. The equation I used was, error divided by the accepted ratio times 100. For example, if I took the error of the experimental ratio for the paper towels, which was 0.12. I took that and divided it by the accepted ratio giving me .03821651. Then I multiplied that by 100 giving me ...
