The largest human DNA molecule is a double helix consisting of two complementary polynu- cleotide chains, each chain in turn being made up of about 250 million linked nucleotides (i.e., 250 Mbp). Given that the average molecular weight of a nucleotide is about 325 g/mol and that there are 2.2 pounds in one kilogram, show the calculation of the mass in pounds of one mole of this DNA molecule.

The molecular target, a protein that allows entry of the novel coronavirus into infected cells, has been identified. Describe in at least three paragraphs the biological function of the target of the novel coronavirus, in which types of human cells is this target found and which could be the relationship between this receptor and the mechanism of coronavirus disease. Suggest how this information could be utilized to develop a new antiviral drug against the novel coronavirus.

A sample of human brain volumes (cm3) is given below. Use the given data values to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. 1067 1075 955 1415 1075 1050 1072 1033

10. (a) The persistent organic pollutants (POPs) that transport via atmosphere into the Arctic have their unique chemical signature. Explain this statement by comparing their chemical properties with POPs that stay near the source region and appropriate examples. (b) Describe the significance of the global distillation model in understanding the long-distance transport of POPs to the arctic. (c) What are the long-term ecological and human ramifications of POPs contamination in the arctic.

Chapter 21: Helminth Parasites and Arthropod Vectors
1. What are the three major taxa for the parasitic worms we studied? 2. What are the distinguishing features of these taxa? 3. What is an exemplar of each taxon? How is it transmitted? What are potential complications? What is the geographical distribution? 4. Are there alternate hosts? If so, what are they? 5. What are the two taxa of arthropods that are involved in human/animal disease?
