42) Using dead diatoms to "pump" CO2 to the seafloor is
feasible only if dead diatoms sink quickly.
Consequently, application of mineral fertilizers, such as iron,
should be most effective at times when
diatom valves
A) are thickest, and laminarin is being produced rather than
oil.
B) are thickest, and oil is being produced rather than
laminarin.
C) are thinnest, and laminarin is being produced rather than

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...
