1. Trypan blue is an azo dye that is cell membrane impermeable and therefore only enters cells with compromised membranes. Therefore the correct answer is dyes unhealthy cells blue.
2. Viable cell are cells that are alive
3. The correct answer is (D) There are more trypan blue positive cells in the experiment flask compared to the control flask. The reason is more cells have compromised membranes in the experimental flask and are stained blue as compared to the intact cells present in the control tubes.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
