Question 8
Ans:- Genetically different cells within a clone.
A strain is a genetic variant or subtype of a microorganisms . Ex, Escherichia coli is a well studied bactrium and encompasses an enormous population of bactria that exhibit a very high degree of both genetic and phelogentic diversity, that is strain.
Question 9
Ans:- rRNA sequences
Phylogeny refers to the evolutionary relationship between organisms.phylogeny based on differences in the sequence of nucleotides in the cells ribosomal RNAs (rRNA).rRNA structure is useful because rRNA molecules throughout nature carry out the same function,their structure changes very little over time.Therefore similarity and disimilarities in rRNA nucleotide sequences are a good indication of how related or unrelated different cells and organisms are.

QUESTION 1 When transforming bacterial cells, a researcher is interested in generating bacteria that exogenously express the gene that encodes GFP (green fluorescent protein). After transformation, she finds that no bacteria colonies grew on her selective media. Which of the following best explains the results of her transformation protocol? The concentration of the antibiotics in the selection media was too low, therefore no bacteria grew. Her bacterial cells were not competent so they took up excessive amounts of...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?

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...
