Select all that apply. The thickness of the main sequence in the H-R diagram is due to: A. The luminosities and surface temperatures of main-sequence stars changing slightly as they convert hydrogen to helium in their cores. B. Main-sequence stars of identical mass but different metallicity having slightly different luminosities and surface temperatures.

Which of the following statements about red giant stars are true? (Select all that apply.) Red giant stars are less luminous than main sequence stars of the same temperature. Red giant stars tend to be more luminous than main sequence stars of the same temperatures because they are larger in size. Red giant stars are less luminous than main sequence stars because fusion happens more rapidly in main sequence stars. A red giant star of a given temperature is more...

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...
