Microbiology Lab Quiz #2 Study Guide Exercise 9 -- The Gram Stain Compare and contrast simple and differential staining techniques. Simple Staining Simple staining is useful in determining the basic morphology of an organism. Simple staining involves only one reagent i.e. crystal violet‚ basic fuchsin‚ or methylene blue. Simple dyes used to stain bacteria have a positive charge cationic (+)‚ therefore‚ they are attracted to the bacteria that are usually negatively charged anionic (-) Depends

Worldview Questions and Answers – Week 2 As we begin this second week of COUN 506 we are going to concentrate on building models for integration in counseling. Our beginning point in this is to understand more specifically how OUR worldview impacts the models that we use in counseling. The way we interpret behavior has a lot to do with our worldview‚ and a lot to do with our expectations of our clients. One of the first steps in applying worldview questions to counseling is that we have to
