[Q1] You are observing microbes with the 100x objective. What is the total magnification?
[Q2] Which organism is positive for mannitol fermentation and alpha hemolytic?
Homework Answers
Q1. Answer - 1000x
Objective lens of 100x when combind with 10x eyepiece , the total magnification = 100x * 10x =1000x
