Obesity Solution

The article, “Clinton: U. S. Risks ‘Collapse’ Without Obesity Solution,” was published in CNN International Online. The United States former president, Bill Clinton, was in the forefront talking about obesity as a national crisis regarding the health and well-being of over thousands of Americans all over the country. Clinton claimed there is an apparent reason why the factors contributing to obesity should be wiped out, because it endangers the future of the nation. The Centers of Disease Control and Prevention has released some figures, which reveal the overwhelming number of Americans who are obese. CDCP stated that for the total population of adults, two-thirds of them are obese, and for the total population of children, one-third of them are obese….

An overview and Presentations of Possible Solution

Ethical operation is an important issue discussed in the case. Ethical issues are brought out if it considered that social corporate responsibility is a major point of discussion. The organisation feels that it is time it paid back to the community that has for a long time played an important part in ensuring it stays operational. However, the main challenge that Kava is faced with is sustainable development. All discussions clearly show that sustainable development is lacking in Kava. The disasters, poor standards of living and a state of neglect are some of the factors that point to the fact that ensuring sustainable development is the key challenge that Kava is faced with; past practices appear to have been least…

Potato Osmolarity Lab

Purpose: The purpose of the lab is to discover the osmolarity of the potato tissue. Background Information: Osmolarity is a concept similar to concentration, except it is the total number of solute particles per liter. In this lab we can show osmolarity by using sucrose solutions and potato ores. This experiment displays hypertonic, hypotonic and isotonic solutions. A hypertonic solution is a solution with a relatively higher concentration, hypotonic cis relatively lower, and isotonic is the same. Variables: Constant = size of potato core Independent = sucrose molarity Dependent = mass percentage change Safety: Follow lab safety protocol and be careful with cork borer. Procedure: 1. With a cork borer, cut six cores from a potato. The cores should all…

Molar Mass of a Solid

Abstract: The purpose of this experiment is to determine the molar mass of an unknown solid. The freezing point of a solvent (Cyclohexane) was determined, and compare to the freezing point of Cyclohexane with the addition of two different concentration of unknown solid. The pure substance of Cyclohexane has defined physical properties. However, when a solute is added these properties are determined by the amount of solute added, also known as colligative properties. The temperature of the freezing point was lowered when the solid was added and it decreased as the concentration of the solid increased. The molality of the solute was determined, which was then used to calculate the molar mass of the solid for both trials. An average…

Conventional wisdom indicates

Many books on the market discuss the differing nature of the sexes. Conventional wisdom indicates that a man asked how to get someplace that he will give directions laced with compass points, tenths of miles, and street names. The same conventional wisdom indicates that a woman, asked for the same information, will give directions that contain landmarks, usually followed by the warning that “if you see [fill in the blank] then you’ve gone too far. ” I chose Dowd’s book due to her approach to this age-old issue. She discusses this dichotomy using sharp wit, which seemed appealing. Her work leaves many readers laughing at her observations, many of which were broad enough to be perceived as parodies. Her humor,…

Determination of Copper by Complexation

ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation, solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper is an essential mineral in everyday life, it is in necessary for the production of red blood and it also keeps the immune systems, nervous system ad hones healthy.[7] Too much copper in a diet can possible health risks. There are several different ways to determine the concentration of copper in the unknown solution such as colourimetric…

Determining the Osmolarity of a Potato

Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation, several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose weight showing that it is a hypertonic solution. Teachers can use this experiment to help teach students the concept of osmolarity and tonicity in a real time situation. Introduction Sucrose is a carbohydrate that is used for energy. Potatoes contain…

Food Dye Lab

Abstract: The purpose of this lab was to determine the food dyes present in a selected beverage, their concentration, and then replicate the solution within a 20% margin of error. The beverage we chose was Gatorade Frost Riptide Rush. A spectrometer was used to determine which food dyes were present in the sampled beverage, red 40 and blue 1 were determined to be present. The next step was to determine the concentration of the dyes, this was done by testing the absorbance of the red 40 and blue 1 dyes at varying concentrations; 100%, 80%, 60%, 40%, and 20%. The results for each dye were then plotted in a graph and a trendline was added. The slopes of the trendlines…

What is the role of 0.25M sucrose as the medium for the fractionation process?

1) What is the role of 0.25M sucrose as the medium for the fractionation process? Cold sucrose does not chemically react with cell organelles  Due to the density and size of sucrose molecules, it is able to suspend pellets for configuration while providing a solution where the centrifugation can be better balanced Sucrose offers a liquid medium in which less dense fractions can be poured off as supernatant at the end of each centrifugation step. 0.25M sucrose solution is isotonic and therefore inhibits the premature lysis of the mitochondria membranes during the fractionation process (centrifugation) 2) List the major components that are present in (a) pellet P1 and (b) Supernatant S2. Pellet P1 contains: Whole cells Cytoskeletons (i.e. plasma membrane)…

Beer’s Law Lab Report

Abstract: The Beer’s law lab was conducted to determine the optimal wavelength of Co(NO3)2·6H2O with the use of spectrometry. The results determined that the optimal wavelength to study the absorbance of this salt was 500nm. It also demonstrated how transmittance of light and absorbance of light are inversely proportional because absorbance is calculated by multiplying transmittance by a negative log. Introduction: When one is studying chemicals, there are many important factors of significance. The color of a chemical is a useful tool in its study. The light one sees produced by a chemical is the result of both reflection and absorbance of wavelengths. The wavelengths that are absorbed by a chemical are not visualized. The wavelengths that are reflected back…
