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 …

If a Ca2+ channel opens in the plasma membrane, those ions will flow out of the cell by facilitated diffusion.

If this is the sequence of DNA, what RNA would be made from it?  Be sure to label the 5′ and 3′ ends. 3′ AATCGGTAGCA 5′

Lab simulations on Connect only use a mouse to engage with the virtual lab environment; there are no keyboard shortcuts for any actions in the virtual laboratory.

Which routing algorithm, Dijkstra or Bellman-Ford, is better at responding quickly to changing connections in the network, i.e., quicky creating new routing tables when one new node is added, or when a link goes down.   Answer Format Write your choice (Bellman-Ford or Dijkstra): [RoutingAlgorithm] Provide your reason for your choice: [Reason] (one or two sentences in text)
