strawberry‚ mixing the pulp with the detergent mix thoroughly‚ pour the detergent mixture into the funnel. Let the liquid from the mixture drain into the beaker then add the ethanol to the mixture. Data: Observations- The ethanol sat on top of the detergent due to its lighter density. Bubbles started rising as soon as the ethanol was added durn turning the liquid cloudy. The DNA grouped rapidly‚ taking no longer than two to three minuets total before slowing down and seeming to stop grouping.

2.12. Histological examination For histopathological examination‚three samples of ears or paws from the control and extract treated animals were taken and fixed in 10% formaldehyde solution for 1 week. Then‚ the fixed biopsies were embedded in paraffin and cut into 3–4 mm slices. The slices were mounted on glass slides and stained with hematoxylin and eosin for light microscopy analysis. The assessment was conducted by a pathologist in a blindedway. 2.13. Statistical analysis The data were expressed

Northeast Iowa Ethanol‚ LLC trusted in Drizin to assist them in additional funding for their project (Cheeseman‚ 2010‚ p. 584). Instead‚ Drizin acted carelessly and from the sound of it did what he wanted to do with their money.

Different solvents provided extracts with different colour values at varying temperatures. At 50⁰C‚ the maximum colour value was found to be in the extract obtained using ethanol as the solvent. As shown in Figure 4.5‚ it could be clearly analyzed that different colour values are obtained on extraction with different solvents. Ethanol gave the maximum colour value i.e. 308.6; chloroform gave a slightly less value of 296.6; followed by methanolic extract giving 249.3

The distillate was collected in a calibrated and numbered test tubes and the temperature was recorded as well. The group was able to acquire 22.50% of ethanol in the compound and got 22.50% of error in the simple distillation experiment. INTRODUCTION Distillation is a process of separating and purifying liquid mixtures‚ where one substance is separated from another by condensation and evaporation.

The only cells in our body that can metabolize ethanol are in our liver. In the cells NAD+ oxidizes the ethanol to acetic acid‚ which generates an excess amount of NADH‚ which gives its electrons to the ETC. Then Oxidative phosphorylation occurs without the Krebs cycle. The carbohydrates that normally enter the Krebs cycle are turned to fat because the Krebs cycle is turned off. The fat is then secreted by the liver into the blood. The ethanol enters our bloodstream through our intestines into

Ether is an anesthetic that works on the brain and puts it to sleep. The same symptoms operating patient experiences under ether are those experienced by a person drinking alcohol.intro Ethanol is commercially produced using a process called fermentation. Many other alcohols can be made this way‚ but are more likely
