Lab 1: Scientific Method Using Lifesaver Elia Ocasio Bio 121 K.L. Box Performed: August 29‚ 2013 Submitted: September 5‚ 2013 Introduction The solubility depends on the properties of a solvent that will allow interaction with a solute more strongly than do solvent particles together. Water is the universal solvent. Water‚ certainly dissolves many types of substances and in greater amounts than any other solvent. The salt is a compound consisting of various minerals‚ and is one of the most abundant

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Summative assessment is designed to measure student understanding of required learning objectives that have been taught. The results of these assessments determine a student’s overall understanding or mastery of the assessed subject. According to the Eberly Center of Teaching Excellence‚ “The goal of summative assessment is to evaluate student learning at the end of an instructional

First‚ the buffer was prepared by using the formula as follows: Figure 1: Calculation for prepare 0.1 M potassium phosphate buffer at pH 6 3.4007g of potassium phosphate was weighed and placed in 300 mL beaker. Then‚ 125 mL of water was added into the beaker that contained potassium phosphate. The mixture was dissolved using the stirring rod‚ and then the magnetic stirring bar was placed in the beaker for further dissolve when measuring the pH. The pH meter was used to measure the solution
