1) The condenser lens concentrates light and makes illumination of image more uniform. 2) The bending of light is also known as refraction. 3) Total magnification = ocular lens magnification x objective lens magnification. 4) The total magnification of an image is 1200x and the magnification of the ocular lens is 10x. What is the magnification of the objective lens? Y = objective lens 1200x = 10x X y 1200x / 10x = y y = 120x Objective lens magnification = 120x 5) The limit of resolution

Introduction: The purpose of this lab is to use staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate
