You have discovered a new species of marine bacteria (E. favoritus) that produces an enzyme that you call petrolease (pronounced: peh-tro'-lee-aise). Petrolease breaks down hydrocarbons in crude oil; therefore, the bacteria may be useful in cleaning up crude oil spills in the ocean. The naturally occurring enzyme functions best at 25 degrees C. Below that temperature there is a continuous decline in activity until 0 degrees C when activity drops to zero. You have isolated and engineered the gene for petrolease to have greater activity at lower temperatures. You determined enzyme activity for both native and engineered petrolease over a range of temperatures from 0 to 35 degrees, repeating your tests several times. a) What is the independent variable for this study?
b) What is the dependent variable for this study?

Cultures of the lake of the ozarks water samples were grown on enrichment media for identification. however, these organisms are present to some degree in all samples. an important question from a clinical perspective is whether or not there is a significant increase in the fecal coliform populations that would put people's health at risk. if you were part of the team investigating this outbreak, how would you best enumerate the fecal coliform threat? view available hint(s) cultures of the lake of the ozarks water samples were grown on enrichment media for identification. however, these organisms are present to some degree in all samples. an important question from a clinical perspective is whether or not there is a significant increase in the fecal coliform populations that would put people's health at risk. if you were part of the team investigating this outbreak, how would you best enumerate the fecal coliform threat? direct microscopic counts filtration count culture serial dilution count culture plate count culture
