Introduction Identification and classification of bacteria is important to make easier manipulation on the bacteria for various purposes such as for medical‚ research‚ developmental‚ and biotechnicalfieldsThe cell wall is the basis for classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry

Microbiology is the branch of Biology that deals with the study of microorganisms and how they influence or work with other living organisms. (Satellite Events Enterprises Inc.‚ 1999) In this paper I will discuss the history of Microbiology and specifically the early theory of spontaneous generation. I will discuss three spontaneous generation experiments and explain why it is obsolete in today’s science. History of Microbiology Since Microbiology is the study of microorganisms‚ it is understandable

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
