Discuss how to protect yourself from body fluids‚ such as saliva and blood. o Gloves protect you whenever you touch blood‚ body fluids. The use of gloves also decreases the risk of disease transmission if you are pricked with a needle. Always wear gloves for handling items or surfaces soiled with blood or body fluids. o Wash your hands and other skin surfaces immediately after they come in contact with blood or body fluids. o Masks and protective eyewear‚ such as goggles or a face shield‚ help protect

Jell-O Lab Guiding Question: Are some laundry detergents better than others? Purpose: We intend to test if the cost of a detergent affects its quality but putting 3 drops of Jell-O into 25mL of Jell-O and examining how much of the Jell-O dissolves. Hypothesis: If the cost of the detergent increases‚ then the amount of Jell-O dissolved will increase by 0.3 cm. Materials/Equipments: * 4-1mL Pipettes * 5cm long standard drinking straw with a diameter of .6cm. * Jell-O brand

Alvaro Comino LAB REPORT 4 CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II. Introduction Apart from the bone and cartilage‚ the rest of the specialized connective tissues are divided

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

Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present

Biology Investigation: Effect of different concentrations of sucrose solutions on the mass of potatoes Research question Is the mass of potatoes going to be smaller or bigger in different sucrose concentration? Introduction Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water
