  A router with IP address 138.76.29.7 manages a NAT translation table for a private network. The router uses ports starting from 8000. Each time a new connection is needed, it increments by one. For example, if a host in the private network with address 10.0.0.5:5000 sends a message to 132.239.8.45:80 then the entry in the NAT table would be filled in as below. The next time the router will use 8001 as the port to establish a new connection and so on.  All connections are TCP. Complete the NAT Table for the following events:a) 10.0.0.5:5000 sends a message to 132.239.8.45:80 (already filled in)b) 10.0.0.6:5000 sends a message to 74.125.239.33:80    Private Address Private Port External Address External Port Transport Protocol a) 10.0.0.5 5000 132.76.29.7 8000 TCP b) [Privateb] [PrivatePortb] [Externalb] [ExternalPortb] TCP    

If you are using the 10x objective lens with one of the microscopes used for the virtual simulations in Lab 1, what is the total magnification of the image? Type the best answer below in the text box:

When handling body fluids, there are seven Universal Precautions that everyone should follow to keep themself safe and free from infection with bloodborne pathogens.  In the space below, describe ALL SEVEN of these universal precautions using complete sentences.

Proteins in this functional category move polar solutes or ions across the plasma membrane. Type the best answer into the text box below:

Which of the following body fluids DOES NOT require extra safety and handling precautions in the laboratory?

Learning more about enzyme function and modulation was a huge part of Lab 3, so hopefully you absorbed that information.  In the essay space below, briefly describe FOUR distinct “fun facts” or characteristics (1-2 sentences each) that apply to ALL enzymes that you learned in Lab 3 or in our Unit 1 & 2 lectures. As always, write in clear, complete sentences if you expect to earn full points.

Consider the previous problem and the same figure copied below. (All link costs in the network have strictly positive values.) Suppose the value of the link cost from Node 1 to Node 3 changes. What kind of change in the value (e.g., greater than x or less than y) would cause Node 1 to have to generate a new minimum-cost path to Node “8” in the next run of the distance vector algorithm? Answer format a) What is the change in the value of the link from node 1 to node 3 would cause a new route calculation at Node 1? The value should be greater than [Greaterthanvalue] The value should be less than [Lessthanvalue] b) How will this impact the minimum cost calculation?  Enter impact in one or two sentences: [Impact]    

In an aqueous 10% dextrose solution, _________ is the solvent.  Type the best answer below in the text box:

In Lab 2, you conducted a virtual lab simulation that used a dialysis bag that was placed into a beaker of fluid.  Remember that dialysis bags are like artificial cells, such that their membrane is selectively permeable to solutes and solvents. Imagine that you have a dialysis bag filled with a 3 M glucose solution.  That dialysis bag is placed in a beaker filled with a 2 M NaCl solution. Assume that both of these solutions are aqueous and this dialysis bag material is impermeable to both solutes, but permeable to the solvent. In the space below, briefly describe what will happen to the volume of fluid inside the dialysis bag over the next 30 minutes and explain HOW this change will happen. PRO TIP: You may want to draw this situation out on your scratch paper so you can visualize what’s going on …
