Unit 3 Study Resource Meiosis • Process by which diploid cells create haploid cells NOT part of the cell cycle > only some cells ever undergo meiosis During meiosis I, homologous chromosomes line up to allow them to be separated into two new cells o They can become "tangled" during this phase, which leads to crossing-over (rearranging the alleles) O Result of meiosis I is two non-identical haploid cells Meiosis Il looks very similar to mitosis, in that sister chromatids...

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...
