Investigation Process There were several steps taken by the police in this homicide case. The main aspects of this homicide investigation process were the initial response to the crime scene‚ collection‚ documentation and preservation. Investigation Process Failure Main Factors There are three major mistakes police made in the investigation process. First of all‚ the crime scene investigation. After identifying the victims and finding 2 children remaining at the scene‚ the police officers

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

Hypothesis: the higher the concentration of hydrogen peroxide the faster the reaction will occur and the more foam will be produced. Aim: The aim of this investigation is to determine how the concentration of hydrogen peroxide effects the intensity of the reaction. Variables: Independent- The concentration of hydrogen peroxide. Dependant - The intensity of the reaction. Constants – The temperature‚ the amount of liver‚ pH level‚ test time‚ Materials: Solutions of hydrogen peroxide varying

Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

Crime scene investigation requires the handling all types of potentially hazardous material‚ from blood and other physical evidence collected at the scene to the chemicals and other materials used by technicians as they perform their jobs. Failure to follow established safety and health procedures regarding the handling and disposal of hazardous material exposes crime scene technicians and others to a variety of risks. Technicians collecting evidence at crime scene must handle a range of biological

The Method of Scientific Investigation Scientific investigation in my own words is when someone breaks down a problem to find a solution scientifically‚ but there can be more to it than just investigation a problem scientifically. Thomas Huxley explains scientific investigation in more depth in his “The Method of Scientific Investigation” essay‚ what is he trying to say in this passage? It could be many things‚ it could be nothing or it could be something‚ we’re basically trying to find out what

hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered‚ can alter the procedure of the reaction‚ such as temperature‚ pH‚ and the concentration of either the enzyme or the substrates. Enzymes are specialized class of protein
