Aoife studies a culture flask of microorganisms. The culture flask has a total volume of 859 mL. Every day she takes a 6-mL sample and replaces the volume with sterile media so the total volume in the flask remains the same. After 87 days, what percent of original culture remains? When performing the math, don't forget that every sampling event counts as a dilution. Perform all calculations in a single step using Excel to avoid accumulating rounding error. Report your answer to 2 decimal places. A blood concentration of 0.065M ethyl alcohol (EtOH) is sufficient to induce a coma. At this concentration, what is the total mass of alcohol (in grams) in person whose total blood volume is 4.99L'? The molar mass of EtOH is 46.09/mol. 0 Calculate to one decimal place . Read about significant figures and rounding in the @pful Resources page! . Do not include units when reporting your answer . Use standard notation as accepted by Canvas . e.g. 0.001 What volume of water (in mL) would be added to 14.5 mL of a 0.14 M solution of sodium borate in order to get a 0.05 M solution? . Calculate answers to 3 decimal places . Read about significant figures and rounding in the Helpful Resources page! . Do not include units when reporting your answer . Use standard notation as accepted by Canvas o e.g. 0.001Here is a M EHO a data set that contains the body masses (in grams) and basal metabolic rates for 17 species of primates. Input numeric answers to four decimal places. Scientists want to know if body mass is an acceptable predictor of metabolic rate for primates. Use this information and the provided data set to answer the following questions. Which, body mass or basal metabolic rate, is the control variable? Which, body mass or basal metabolic rate, is the response variable? Using Excel, graph the data as a scatter plot, then right click the data set to add a trendline. Format the trendline so that it includes the equation and the R2 value. What is the slope of the trendline for the data? What is the y-intercept of the trendline for the data? What is the R2 value of the data set? Is the linear model a good fit for this data, yes or no? Using the Analysis ToolPac Add-In for Excel, perform a regression analysis on the data set. What is the P value for the t-test that the slope of the line is not equal to zero? 0 Report the P value in scientific notation just as you see it in Excel. 0 eg. 0000000012345 would be 1.12345E-8 0 Report your answer to four decimal places. Is the slope of the line significant, yes or no?
