Please explain the following observation:
For chain-growth polymerization, the concentration of the monomers
follows a slow mono-exponential decrease. For step-growth
polymerization, the monomer concentration follows a very rapid
bi-exponential decrease.

Please explain why for 3&4
our diferent-richuring antibic Data Analysis: Tube (Broth) Dilution Test The following data were obtained for four different antibiotics (Doom, K.O., Mortum and Steril) by incubating Pseudomonas aeruginosa in a nutrient-rich medium with various concentrations of each antibiotic for 24 hours. This was followed by a subculturing step where each initial culture was used to inoculate a sterile nutrient-rich medium that contained NO antibiotic. Please use the following table to answer questions #1-4 below. (5 points...

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...
