Aim: To test the effect of decay in processed foods vs. non-processed foods Hypothesis: The processed foods will last longer than the non-processed foods because they contain more preservatives and artificial ingredients. Background Information: Preservatives are often added to food to prevent their spoilage‚ or to retain their nutritional value and/or flavor for a longer period. The basic approach is to eliminate microorganisms from the food and prevent their regrowth. This is achieved by

Determining the Production of Glucose During Changes in Temperature and pH‚ and Manipulation of Specificity and Cofactors BIOL-1406-SL8 November 16‚ 2012 Abstract Enzymes are biological catalysts. They work by lowering the activation energy needed to initiate a chemical reaction. Enzymes work within an optimal temperature and optimal pH. Enzymes are highly specific for a single substrate. The Enzyme is usually much larger in size than the substrate it binds to. In some cases‚ an enzyme requires

Why does early and forced marriage happen? The causes of early and forced marriage are complex‚ interrelated and dependent on individual circumstances and context. But the practice is driven by these main factors: gender inequality – women and girls often occupy a lower status in societies as a result of social and cultural traditions‚ attitudes‚ beliefs that deny them their rights and stifle their ability to play an equal role in their homes and communities poverty – in families on a low

Effect of Greywater Irrigation on Soil Hydraulic Properties Henry Hartono Gunawan 1 INTRODUCTION The use of Greywater for landscaping irrigations is becoming common as Western Australia is experiencing the water restriction due to the current drought condition and critically low level surface water storage. Hence‚ the reuse of Greywater can utilise the on-site resource‚ conserve the water efficiently‚ and reduce the load on wastewater disposal system. As there is still lack of information

Water pollution is a serious matter‚ and can be defined as a problem. Poor water quality is just another way of saying water pollution. Water pollution is when one or more substances build up in water to such an extent‚ that several problems for animals and humans develop. Rivers‚ lakes‚ oceans‚ and other inland waters are able to naturally clean up certain amounts of the pollution by dispersing them harmlessly. Water pollution depends on the quantities: how much of the polluting substance is released

Respiratory acidosis is the result of too much carbon dioxide and not enough oxygen in the blood. This condition can be caused by chest injury‚ chronic lung disease‚ or overuse of sedatives. ABG results will show a low pH and a high PCO2‚ according to Lab Tests Online. Respiratory Alkalosis Respiratory alkalosis can occur if a patient hyperventilates.

FERMENTATION) . In this experiment we will be testing the fermentation of yeast using a several different molecule solutions. HYPOTHESIS: The hypothesis was that the yeast glucose solution would produce the most carbon dioxide. MATERIALS: In this experiment we used 4 large test in which we placed the dry active yeast and 30ml of heated distilled water. We also used a balance to weigh and a spatula to acquire the yeast‚ 250ml beakers‚ and a 10 ml pipette to measure. Of what was measured were
