EFFECT OF BIODEGRADABLE SM PLASTIC BAG IN DIFFERENT SUBSTRATE ABSTRACT The purpose of this Investigatory project is to determine the effect of different substrates on the biodegradability of SM plastic bags. The materials needed are: 6‚ 1-litre glass jars; 6‚ 7”x9” aluminums trays; 12 pcs. 3”x4” SM plastic bags; 500g loam soil; 500g compost soil; 500mL seawater; 500mL tap water; Analytical balance; Graduated cylinder; and Weighing scale. The procedure involved cutting the SM plastics bags

The hypothesis that I draw is that "" out the five carbohydrate substrates that I will use‚ Glucose will produce the highest volume of Carbon Dioxide at every five-minute interval. Null Hypothesis. The null hypothesis that I am composing is that "" the five carbohydrate substrates that I am to use will not produce any Carbon Dioxide. Scientific Research. Under anaerobic

enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic respiration while the process that does not

such as fructose. The enzyme helps a chemical reaction take place quickly so that the reaction happens properly. In order for that to happen the enzymes process by the lock and key model‚ the lock is the substrate and the enzyme is the key. The active sites are specific to a certain substrate of a molecule‚ so the enzymes only have one job to do. The shape of an enzyme is not changed or consumed during these reactions. However‚ without enzymes the reactions would take too long and would not breakdown

Effect of Substrate Choice On Growth Of Mealworms Abstract: The experiment is designed to show which substrate A or B will better nourish a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth
