You have discovered a new microorganism and would like to classify it as a eukaryote or a prokaryote. to investigate this question you prepare a slide with a simple stain and view it with a light microscope with a 40x objective lens and 10x ocular lens. you also prepare a control slide using saccharomyces cerevisiae (a unicellular eukaryote). you can see the cells on your control slide, but you don't see cells when you look at your unknown microorganism. what can you conclude from this experiment?

Jane is blood type a her husband is blood type b. jane is puzzled because their daughter is type o. explain how the daughter inherited a blood type that neither of her parents had explain your answer

You are studying several alleles of an e. coli helicase gene. one allele, called rsr, confers resistance to rs2014, an antibiotic that works by inhibiting helicase activity. bacteria with the rss allele are sensitive to rs2014. another allele, called ts-, produces a temperature sensitive mutation of the helicase. in bacteria with the ts- allele, helicase is inactivated at 42 °c but functions normally at 37 °c. helicase functions normally at both temperatures in bacteria with the ts allele. you obtain the following data while testing four strains of e. coli at different temperatures and doses of rs2014. each number represents the percentage of maximal dna synthesis. based on this data, assign the appropriate genotype to strains a–d in the spaces provided
