This image shows the rock cycle. The Rock Cycle. Arrows point from 1 stage to next. 1. Metamorphic Rock to point K to Magma to point V to Igneous Rock to Melting back to magma. 2. Metamorphic Rock to point K to Magma to point V to Igneous Rock to Heat and Pressure. 3. Metamorphic Rock to point K to Magma to point V to Igneous Rock to Weathering and Erosion to Sediment to Compacting and Cementing to Sedimentary Rock to Heat and Pressure to Metamorphic Rock. 4. From Sediment to Compacting and Cementing to Sedimentary Rock to Weathering and Erosion back to Sediment. 5. Metamorphic Rock to Weathering and Erosion to Sediment. Which event most likely occurs at point V?

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
