What is the name of the fluid that lines the alveoli that keeps them from collapsing?

14. (3 bonus points to exam 2) A point in a structure sees the following stresses σx = 1 ksi, σy = 2 ksi, σz = 3 ksi. What are the associated strains εx, εy, εz, knowing the modulus of elasticity is 30ksi and Poisson’s ratio is 0.3. If for a different point in the same structure with the same material, the strains are εx = 0.001, εy = 0.002, εz = 0, what are the σx, σy, σz stresses at that point?

What is medical term for fluid within the lungs?

8. (10 points) For the beam in problem 5, what is the magnitude of the transverse shear stress in Segment 1 (0 < x < 1 m) at a location on the square cross section where the I = 8∙10-10 m4, Q = 1.25∙10-7 m5, the height and width of the square cross-section are 0.01 m.  Show all your work and calculations. Upload together with other solved problems at the end of this exam. 

4. (15 points) Draw the shear diagram for the beam subjected to the loading conditions shown in the Figure below. Specify the shear value throughout the beam. If the shear value changes through a segment, call out the beginning and end values of the shear on that segment. If the shear value is zero at a point in a segment, specify the location where that occurs. Show all your work. Upload together with other solved problems at the end of this exam. 

Find below tables that you can use in solving some of the problems (Second Moment of Area and Beam Deflections). This is not an exam question – just information.

  The bacteria growing on plates containing ampicillin are replated onto agar containing ampicillin and X-gal.  Bacterial colonies will grow, however some colonies will be blue and some white.   Which bacteria represent the white colonies? [white] Which bacteria represent the blue colonies? [blue]

1. (3points) For the composite cross-section shown in the figure below, determine the location of the neutral axis relative to the x-axis. Include units in your answer. Point A shown is used for a future problem, not this one. Show all your work. Upload together with other solved problems at the end of this exam. 

Using the information in the table, complete the restriction map for pGMO by identifying the appropriate restriction enzyme for each restriction site. (10 points)   A: [siteA] B: [siteB] C: [siteC] D: [siteD] E: [siteE] For each lane in the electrophoresis gel, select the restriction enzyme that will yield the size and number of DNA fragments.   A: [digestA] B: [digestB] C: [digestC] What restriction enzyme would you use to digest the pGMO plasmid before insertion of the aroA gene? [enzyme1] The diagram below represents a section of a plant genome. The coding sequence of the aroA gene is shown by a yellow box. Locations of restriction sites for the three common restriction enzymes (EcoRI, BamHI, and KpnI) are also marked. What restriction enzyme would you use to digest the aroA gene for insertion into the pGMO plasmid? [enzyme2]  

Please mark your agreement with the following statement: I understand that the Cumulative Final Exam is an assessment of my knowledge and application of nutrition for health professionals. I will do my own work and I will not collaborate with my peers. I can think critically and synthesize nutrition information on my own, and I understand that use of AI to generate responses for this assessment is not acceptable. If I have questions about the exam, I will ask for help from the instructor or graduate teaching assistant.
