Essays on Determination

The objective of this experiment was to determine the elting point and boiling point of malic acid and ethyl acetate through the rough and accurate method, and compare them to the theoretically obtained ones. The objective was achieved seeing as the melting and boiling point of the samples were obtained, however, there were deviations from…

The idea of Indeterminate Sentencing is both worrisome and objectionable, as it allows the legislature to set the boundaries for a crime but leaves the judge with the responsibility of deciding the exact punishment for the offender. After examining this data, I strongly believe that while judges should have some discretion in sentencing, they should…

Concerns the finding of the sex glands. In mammals, finding purely chromosomal ; non influenced by the environment. Most cases- female = XX ; male= Xy Every person being has atleast one X Chromosome. Since the female has 2 X chromosomes, each of her eggs posses one X chromosome. The male posses an Ten and…

A large body of research shows that social determinants of health have significant impact on the health of Canadians and Americans. Yet, very few studies have directly compared the extent to which social factors are associated with health in the two countries, in large part due to the historical lack of comparable cross-national data. This…

Method Five sucrose solutions with changing molar concentration and one control incorporating distilled H2O were prepared and poured into trial tubing. The murphy phonograph record were dried, weighed and added to the trial tubing. The phonograph record were so weighed once more after a period of 24 hours. The per centum alteration in mass was…

Determination of presence of protein in a variety of food substances by the use of Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates, lipids, and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with…

During the first decade of the twentieth century it was established that the sex of almost all many-celled biological organisms is determined at the moment of fertilization by the combination of two kinds of microscopic entities. the X and Y chromosomes,‘ This discovery was the culmination of more than two thousand years of speculation and…

The production of reducing sugars by acid of carbohydrate cereals powder, jams (total sugar content) and jams (reducing sugar content) were performed in order to study reducing sugar production. The study involved hydrolysis carbohydrate cereals powder and jams by immersing in boiling water at environmental temperature. Acid hydrolysis was carried out through reflux boiling for…

Statistics is a mathematical science dealing with the collection, organization, analysis, interpretation, and presentation of data. It provides a more accurate way of expressing data rather than mere observation. This experiment used the different statistical concepts such as the Q test, mean, standard deviation, relative standard deviation, range, relative range, and confidence limits or confidence…

Discussion This experiment is about the effect of pH in the activities of catalyse. A cork borer is used to cut out a potato cylinder from the potato. The potato cylinder was then cut into 10 disc shape with even thickness. A test tube was filled with 5 cm? of buffer solution and the 10…
