Based on the text, why might the California's Division of Safety of Dams have
ordered in 2001 that the Calaveras Reservoir be kept at no more than 40%
full?
(A) to limit the potential flooding damage that could be caused if an
earthquake happens and the dam spills over
(B) to increase the potential flooding damage that could be caused if an
earthquake happens and the dam spills over
(c) to limit the amount of water being used during a ume when the state was
experiencing a drought
(D) to decrease the chances of an earthquake taking place and causing the
dam to spill over

Most animal cell membranes have proteins that pump. ions out of the cell and potassium ions into this

In which area of the neuron is an action potential initially generated?

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
