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.

Write the range of IP addresses that fall within the following CIDR address designations and state the number of addresses in the group:  CIDR: 74.21.112.0/21   Answer format:. Range: w1.x1.y1.z1 – w2.x2.y2.z2  (e.g,,. appropriate range within: 0.0.0.0 – 255.255.255.255) Lowest value in range is: [LowestRange] Highest value in range is: [HighestRange]

What is virtual output queuing in a network switch?  Would there ever be a need for virtual input queuing? Explain why or why not.

Show your work for the previous problem. Answer Format: For full credit, your answer must: 1. Provide the formula(s) that you are using with variables only. 2. List the values of the variables. 3. Provide the result. Examples:  Formula used: c=2*t values of the variables:  t=2  result:    c=4 Formula used: E=mc^2 values of the variables: m=2, c=4 result:  E=32    

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)

When performing a Virtual Lab simulation on Connect, you must take notes on your own paper, since there is no way to digitally take notes within the simulation itself.

When a particular concentration of protein molecules are all bound to substrate and all working at their maximum rate, we say that this population of proteins has reached a point of _________.

The following image shows the introns and exons for an mRNA.  The splice sites are labeled below the mRNA. What would be the consequence of blocking site number 3 under intron B so that the spliceosome could not find/recognize it?

Creating more of a particular enzyme through protein synthesis is also called _________. Type the best answer into the text box below:

For the virtual microscope you learned to use on Connect in Lab 1, the _________ should only be used at the lowest total magnification.
