When Jill was just eight she witnessed an ice cream man steal a small child’s ice cream cone. Since then, whenever she sees the ice cream man, she runs and hides her cone. She fears he might steal it. This is an example of what kind of exposure?

Jim has wanted to change some policies at his company for a while. During a meeting with the other CEO’s, he expresses his feelings open and honestly but sacrifices someone else feelings while doing so. However, he feels he needed to say what he said to get his point across. This is an example of what interpersonal behavior or communication:

 Indicate whether each of the following statements related to cancer is likely to be true or false. Cancer cells contain mutations in the genome, but their chromosome number and structure are always normal. [1]  Even though cancer cells divide faster than normal cells, they are less dependent on other cells to provide growth factors.  [2] Because certain mutations in proto-oncogenes contribute to cancer development, cancer researchers should be attempting to design drugs that will decrease the activities of proto-oncogenes. [3] The inhibition of negative immune regulation has been used to develop anti-immune-checkpoint antibodies. These antibodies release a killer cell attack on cancer cells. This has been used for effective treatment of metastatic melanoma. [4] P53 should be classified as a potential oncogene. [5] Tumor progression involves successive rounds of randomly inherited change followed by natural selection. [6]

Indicate whether each of the following statements is likely to be true or false. Gap junctions are important structures for coupling the electrical and metabolic activities of adjacent cells. [1] Extracellular matrix has no effect on tissue formation or regeneration. [2] Tight junctions seal the plasma membrane of adjacent epithelial cells together. As a result, membrane transport across the epithelial sheet cannot occur. [3] “Adhesion belts” contain bundles of intermediate filaments connected across the epithelial cells via cadherins and associated proteins. [4]

Which of the following genetic changes will result in increased activity of the gene product of a proto-oncogene? Answer Yes or No for each case. A mutation that introduces a stop codon immediately after the start codon. [1] A mutation in the promoter of the proto-oncogene, causing the normal protein to be produced at an abnormally high level. [2] A mutation within the coding sequence that makes the protein hyperactive. [3] Loss of a chromosome that contains the proto-oncogene. [4]

You have created a strain of mutant yeast cells that divides normally at 30°C but cannot enter M phase at 37°C.  You found that M-cdk and M-cyclin are not mutated in this mutant strain.  Which of the following temperature-sensitive mutations could NOT be responsible for the behavior of this strain of yeast?

Machine X has established a VPN with Machine Y, which is a VPN server connected to the private network 10.0.20.0/24. With the VPN, a user on Machine X can now access machines on the 10.0.20.0/24 network. The user runs the following command on Machine X: “telnet 10.0.20.100”. The following figure shows the packet flow triggered by this command. Please answer the following questions: Q4345.png (a) What is the relationship between packets ① and ②? (b) What is the relationship between packets ③ and ④? (c) What is the source IP and destination IP of packets ①, ②, ③, and ④? (d) What routing entries are needed on Machine Y?       Hint: e.g., Machine Y$ sudo route add 10.0.20.45 _____                    Machine Y$ sudo route add -net ____________ eth2                    Machine Y$ sudo route add -net _________/16 ____ (e) What routing entries are needed on Machine X? (f) What routing entries are needed on Machine 10.0.20.100?
