- I know I need to plot a Lineweaver-Burk plot, but the manual way I'm trying doesn't make sense. I'm seeing elsewhere that the x-intercept is 0.8 and the slope is 0.32 but I have no idea how those are being found. Could I get a step by step walkthrough of how I plot this in order to get the line equation? Or is there a way to plot it on a graphing calculator?Why B is correct?Which one of these is correct ? And why are the rest incorrect?
- A packing plant fills bags with cement. The weight X kg of a bag of cement can be modelled by a Normal distribution with mean 50 kg and standard deviation of 2kg. a) If a bag is selected is at random, find the probability that the weight of the bag is greater than 55 kg. b) If three bags are selected at random, find the probability that 2 bags weigh more than 55 kg. c) Compute the probability in part a using RStudio.What does the graph imply?Can you please explain why D is correct?
- What is the Lineweaver-Burk plot and what does it tell us?Baker's yeast, Saccharomyces cerevisiae, is a single-celled, diploid fungus (which is, of course, a eukaryote, that is capable of both meiosis and sexual reproduction). Wild type yeast can normally grow on solid or liquid minimal medium; you isolate three mutant strains which are no longer capable of growing on minimal medium alone, however, they can grow on medium supplemented with adenine. All three yeast strains are homozygous for the underlying alleles. When you cross mutant strain 1 and mutant strain 2, the offspring cannot grow on minimal medium alone and require adenine supplementation; when you cross mutant strain 1 and mutant strain 3, the offspring can grow on minimal medium alone and do not require adenine. After crossing the F1 generation of the cross between mutant strains 1 and 3, you count and determine the phenotypes of 1,000 colonies (here a colony is equivalent to an individual): 563 colonies that can grow on minimal medium alone; 437 colonies that require adenine…Baker's yeast, Saccharomyces cerevisiae, is a single-celled, diploid fungus (which is, of course, a eukaryote, that is capable of both meiosis and sexual reproduction).

She calls this mutation quiver, qu, and determines that it is due to an autosomal recessive gene. She wants to determine whether the gene encoding quiver is linked to the recessive gene for vestigial wings, vg. She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits, and then uses the resulting F, females in a testcross. She obtains the flies from this testcross. Phenotype Number of flies vg* qu+ 230 vg qu 224 vg qut vg* qu 97 99 Test the hypothesis that the genes quiver and vestigial assort independently by calculating the chi-squared, X², for this hypothesis. Provide the X2 to one decimal place. X2 = Does the X value support the hypothesis that the quiver and vestigial genes assort independently? Why or why not? the partial table of critical values for X2 calculations to test this hypothesis.
